Re: nitrate filters (not including plants)
There is a new product to consider called Siporax--short, hollow glass
tubes with deep fine fractures. They go into the filter system and can help
reduce nitrates. The fractures are deep enough to house anaerobic bacteria
that break down nitrates. The product is somewhat new in the American
market but has had good word of mouth from Europe.
In a planted tank, however, I would think the plants should get the
nitrates rather than the filter. Doesn't the problem with algae in discus
tanks have to do with the phosphate level?
