    WOW! I was ready to give up this hobby completely! My once beautiful reef tank was a scene from the wreck of the Titanic! Dirty, Ugly. Dying! After using two weeks worth of Algone my tank is once again a thing of beauty. The local marine store is still trying to figure out how I have zero nitrates, when before I was in the danger zone! Thanks Algone-here is a reorder for twice as much! (Need to share with friends!).

  2. David H


    Since I have been using your product my tank has improved 1000%. My fish are healthy, I use less filters and have too clean far less often. Great product.

  3. Richard AS


    I have today placed my third or fourth order for Algone. I find that the product does everything that it advertises. I have no more ammonia! I have no more nitrite! And I have only a very acceptably low reading (less then 5 ppm) for non-toxic nitrate! Equally important to me, is that I have NO MORE CLOUDY WATER in my tanks! Your web site is book marked as one of my favorites. Many thanks for your courteous personnel, your customer service and prompt shipments always.

    P.S. My 30 fish thank you, too!

    Within 2 weeks of putting Algone in our tank, the water was crystal clear and is so now. It was very cloudy and we worked on it for a month to clear it up. Thanks so much.

  5. Dana Glenn P


    Thought you’d be interested to hear that in the space of one week my tank has gone from not working to completely clear! I’m amazed! You can have an aquarium in a south facing solar window.

  6. Phillip T


    I have a 135 gallons aquarium and I have been using Algone for more than 2 years now and the aquarium is great, water is clear and nitrate is less than 10 …. thanks to Algone.

  7. Peter P


    I added a note in the comment box when I placed my first online order of Algone for my 72-gallon aquarium. I said that I’m going to trust you on this. I took a Nitrite test one week after I placed Algone in my Fluval 404 filter and the result…my high Nitrite level is completely gone! The water is also sparkling clean and the fish are very happy and active. My goal was to look for an all-in-one product that would solve my water chemistry problems and do away with the individual products I’ve been buying in the past. Yours is the solution.

  8. Tyler J


    I had used Algone for about seven months and did not notice anything special … until I stopped using it. Within a month nitrates and cloudy water were out of control. Algone is kind of like a good pair of shocks on your car, you don’t notice it until you don’t have it.

  9. Bob B


    Your product Algone is something else. We (my girlfriend Danette and I) had done everything the local pet stores had suggested but just couldn’t get the nitrite level down and were really worried about our fish as success in the past was not the best. But alas, a search on the internet, a decision to call you, and then order the product based on the feeling you really knew what you were talking about has been the best decision we could have made for our fish. Within one week nitrite levels began to come down, second week they were perfect and the water was crystal clear. I enjoy dealing with people who care about their customers, and you guys certainly do.
    Thanks again and stay in touch.

    I’ve been very happy with Algone, both the product and the company itself. I ordered Algone, and within two days, there it was in my mailbox. I put it to work immediately, and Nitrate levels of 60 PPM were reduced to 10 PPM in about 2 days (this in a 55 gallon tank). It’s incredibly easy to use–I just pop a packet in my canister filter, and that’s all there is to it.
    My fish and I are hooked.

  11. Ray B


    I love Algone, it’s just what the Fish- Doctor ordered. It takes the headaches out of maintaining my aquariums- Thank-You.

    My first Saltwater tank was set up in 1968. Fish only at the time. I’m in the reef tank hobby for 3 years now. I keep fish and reef critters in a 40 gallon and in a 30 gallon tank. Snails are great, but Algone is a FANTASTIC help. I just love your Product. Glass is crystal clear,( except for snail eggs) Water is clear and almost Nitrate free. Your web side is fine. I can’t think of any reason to change your layout. You can use my Comments on your side if you wish.

    I have a 3 year old 37 gal reef aquarium, two months ago I developed a “nasty mucky” take-over. Despite my many water changes and skimming of the tank it seemed only to get worse. Finally, the last straw, it killed two of my brains }:-\ I’d read all the feedback about Algone, and it was truly last ditch effort. I used two pouches the first week, and by the second week I could tell that the tank was clearing up. By the middle of the third week, I had “NO TRACE” of cloudy water. It truly saved my aquarium, THANK YOU ALGONE.

  14. Stephen L


    I’ve now got coralline coming out of my ears. Sure beats that aweful stuff I used to have. Thanks Algone.

  15. Todd D


    I must say I wasn’t sure if this stuff would work. Nothing else I tried would get rid of my cloudy water problem and a very high rise of nitrite and nitrate in another tank. I found out what the nitrite/nitrate problem was but was having a hard time getting the levels down. Water changes were just taking too long. After one week with Algone all my problems vanished. This is the most amazing product I have seen for aquariums ever. What is so great is it works for more than one thing. I tried chemicals and nitrite absorbing packs and none of them ever worked. I’ve told everybody about Algone and will continue doing so. This stuff is amazing!!!!!!!!!!!

  16. Tsafrir L


    Amazing! In just a week, my aquarium’s nitrate levels dropped from 160ppm and more to less than 10ppm! I’m going to use it again and again.

  17. Angela D


    I am writing to let you know how much success I have had with your product Algone. I have been using Algone in my filter for about four weeks. I initially bought it to try to get rid of the cloudy water and the ammonia that was building up in my new 72 gallon tank. I have done a water test and for the first time EVER I am showing a reading of 0 ammonia. The cloudy water is gone as well! I am so relieved that I don’t have to worry about the ammonia anymore. Thank you for such an incredible product!! I will tell my local aquarium store about your product. When I asked them what to do about my problems, they of course said the usual water change for the ammonia, and the cloudy water would eventually go away. Well they will have a new answer for people now! “Algone!”
    Thanks again.

  18. Bob C


    I use Algone in 4 of the 5 aquariums at the house. I also use it in all my aquarium maintenance service aquariums. There has been no problem with cloudy water, ammonia or nitrite in any of these freshwater tanks. The nitrate level runs between 0-5ppm. Keeping these tanks sparking clean is good for business and I am proud to say that Algone has helped make my job a lot easier.

  19. Sam O


    Algone is a great product. I had no nitrate in my tank, and I took the pad out for too or three days just to see and guess what? My nitrate started to rise, I put a new pad in and within a day or two my Nitrate dropped back to zero! Thanks for everything.

  20. Dave L


    I received Algone, installed it in a tank which had 30ppm nitrates yesterday…Today it has 15ppm…I’m impressed.

  21. Emma B


    Just wanted to let you know MY GREEN WATER IS GONE !! It’s almost to good to be true. I have fought that green water and run away nitrates since last summer, and now they are gone. I am just thrilled. I have one more packet of Algone for next week and you can bet I will be ordering more. Thanks again.

  22. Kim D


    After my 50 gallon tank cycled I could not get rid of the cloudy water until I used Algone. I use two packs, one in each biofilter, and my aquarium is beautiful. I have little to no problems with maintenance and have five beautiful aggressive cichlids.

    Hi. Just wanted to say how helpful your site has been. I just found it a little too late. I bought a 29 gal. tank for my husband for Christmas. Lost all the fish this weekend in 2 days. We bought everything at a local department chain, I won’t mention the name. We got some bad advice and not knowing anything ourselves we followed the advice of the salesperson. Did all the wrong things. After finding your site today I think we are on the way to getting the problem fixed. Too bad they would not refund anything. I spent approximately 400$$.It was an expensive lesson to learn but your site has given me hope and has lessened the frustration and discouragement, Thanks.

  24. Bernard K


    Terrific Product…It works like magic.

  25. Andy F


    Great product!

  26. Jon F


    What a wonderful product!!! Takes the guess work out of aquarium start-up! Thank you so much for your product, my fish & I just love it.

  27. John L


    Works great…Will purchase again & again…Thanks for such a great product.

  28. Teo S


    I am impressed by the service and quality of your product.

  29. Connie B


    Great Stuff!! I don’t know how we could run the tank without it.

  30. Wayne R


    It works, period.

  31. Richard R


    Your product has solved my problems. it saved me from getting rid of the aquarium I enjoy so much.
    Thanks again.

  32. Thomas S


    Just wanted to let you know, I’ve had aquariums for the better part of the past ten years. During this time I set up my share of tanks and thought I had it down to a science on how to avoid problems with new tanks before they occurred. Then I found your site, figured I’d try your product during the cycling of a new tank I was about to set up. I was skeptical, but let me tell you the tank has been running for over a year now and I’ve never had a more carefree aquarium in all that time.
    Excellent Product! Thank you.

  33. Rachel N


    I really enjoyed your website. I love aquariums, fish, live plants, and most of all to read about them. The only thing I would have to say that I disagree with is the Nov. 14, 2000 fish quiz: the question was about a hospital tank and what it is used for. The answer was for sick fish. In my opinion, especially in marine tanks, hospital tanks are used for any new fish that might bring a disease into the aquarium. You treat the tank with medicine that would kill any bacteria/organism that may be carried on the new fish. Well, I thank you for your time and great website.

  34. Mark C


    Just wanted to thank you for your fast processing of my order.. I live in Ontario, Canada and seriously thought it would take weeks to receive your product.. But, to my surprise, it came in the mail in 1 week!! I’ve wasted no time either, put the pouch in the water filter within minutes of opening the box..
    Is there a Canadian Dist. that would be easier for me to purchase Algone? Don’t get me wrong, it was dead easy to order online.. but it would also be nice to purchase it right from a local store..
    Thanks again for the quick service.

  35. Jo C


    I must thank you for your return reply. I cannot tell you how much your knowledge and information has helped me. I have been going nuts trying to find out about this algae etc. I made an error. My tank is 55 gal. If you think I need to order more please go ahead and order for me what you have recommended in this note. I appreciate you waiving the shipping charges as well. Looks like because of you Algone have made me a bonafide lifetime customer. Thanks again for your help.

  36. Chris T


    I purchased your product 3 weeks ago as a last resort to solve an ongoing 2 month problem of extreme cloudiness in my aquarium. After numerous water changes and tests all coming out with satisfactory levels, I was going crazy trying to clear up the water. I had no idea what to do. I ran in to your site after searching the internet for advice. I figured I had tried everything else, so why not give this a shot. I am very happy to say that 2 1/2 weeks after your product arrived (which only took 3 days) I am now looking at the clearest water I have ever seen in anyone’s setup. The water test levels are now not only satisfactory, but PERFECT. I am so happy with your product, I even gave away 8 packets so far to show my fellow aquarium owners how great your product is. They are all now experiencing the same results and have thanked me over and over. Being relatively new to this hobby, I have found your site to be MORE than helpful and informative. In just two weeks, you have gained a lifelong customer in me – and possibly four of my friends! Thanks again for such an innovative product and I will be ordering again soon.

Add a review “Algone Aquarium Water Clarifier & Nitrate Remover”


Clear Cloudy Aquarium Water

Algone purifies water by utilizing enzymes that break down waste into insoluble complex structures.

Biopolymers polish the water and remove dissolved organic and inorganic pollutants. The result is always crystal clear water.

Often due to overfeeding, harmful substances like organic and inorganic pollutants will accumulate resulting in soft water, low oxygen levels and a crashing pH in consequence. Sudden redox changes will promote algae growth.

Pollutants can not be avoided, but can be removed and inhibited as part of aquarium maintenance with Algone.

Remove Nitrate, Toxins & Pollutants

Algone safely removes and retains nitrates, nitrites, and ammonia. Microorganisms incorporate nitrogen into their cellular mass, while polyelectrolytes assimilate nitrogen directly from the water column.

This greatly benefits all aquarium inhabitants. Ammonia is highly toxic and lethal at any level. Rising and persistent nitrate levels cause issues with sensitive organisms and species, fish, plants, corals, invertebrates, etc.

Algone not only removes but also prevents nitrates and ammonia from negatively impacting the aquarium.

Maintain & Balance

Algone creates and maintains a balanced aquarium, providing a healthy environment for fish and other tank inhabitants.

Most diseases are the result of deteriorating water quality which causes stress on the fish. Stress weakens the immune system and thins the protective slime coat of fish. Both cause an increase in the fish’s vulnerability toward disease that could have otherwise easily been averted.

Reducing nitrates, pollutants, dissolved organics, and other harmful substances with Algone is an organic approach eliminating the need for chemicals.
