Peat Moss Filtration

In my attempt to find ways to keep certain types of tetras that like soften and acidic water I came across a simple and effective solution. Peat moss can be added to the substrate or in the filter to take the calcium out of the water as well as making it more acidic. The peat moss will absorb calcium ions from the water as well as releasing small amounts of acid. This is a cheap and effective solution for those looking at keeping or breeding less hardy tetras or other fish. A word of warning though make sure there is no fertilizer in the peat moss as this will be almost sure to create an algae bloom. I will not be using this unless the fish appear to be suffering in the current water, mainly because I will be running the tank near its maximum capacity (although my Cascade 200 filter will cycle the water completely 6 times every hour) and the added moss will slightly obstruct filtration and I may need all of it to keep so many fish safely.
