Salinity & Specific Gravity
Learn more about salinity and specific gravity for saltwater and reef aquariums. Consistent and stable levels are essential for healthy saltwater fish.
Protein Skimmer for Reef Tanks
The protein skimmer is highly recommended for every saltwater and reef aquarium. A well adjusted skimmer will remove significant amounts of waste from the water.
Is the Water Change Harmful?
Without a doubt, the water change is the most important part of aquarium maintenance. But can the aquarium water change have negative effects on the fish tank?
How to Adjust the pH in Your Aquarium
Learn more about aquarium pH, what it means for aquarium fish, and how to make safe adjustments. A stable pH is very important for fish health.
Activated Carbon and Chemical Aquarium Filtration
Activated carbon is used to remove chemical impurities from the aquarium water. Not surprisingly, this is referred to as chemical filtration. But how does it work?
Nitrites and the Aquarium Nitrogen Cycle
Nitrites are a natural part of the aquarium nitrogen cycle. Nitrite is highly toxic for fish and levels must be kept undetectable at all times. Nitrite can quickly become lethal for fish.
Effects of Ammonia on Aquarium Fish
Ammonia is a toxic by-product of the aquarium nitrogen cycle. It’s the first nutrient produced by nitrifying bacteria. Ammonia should never be detectable in an established aquarium.
Kalkwasser in the Marine Aquarium
Even the most inexperienced hobbyist can easily make Kalkwasser. Kalkwasser is extremely beneficial for corals, coralline algae, and many reef inhabitants.
Chemical Aquarium Filtration
Chemical aquarium filtration sounds more complicated then it is. While the processes may be technical in nature, it is easily achieved with activated carbon.
Aquarium Cycling Without Fish
Consider cycling your aquarium without live fish. Using pure ammonia to cycle the aquarium avoids fish being exposed to harmful nutrients during the process.
Reverse Osmosis for Saltwater & Reef Aquariums
Reverse osmosis (RO) results in the purest drinking water possible. Water is pushed through a dense membrane passing only small molecular weight particles through.
