Are you saying it wouldn't consume any significant amount of nitrates, or that it's not worth doing? Do you think I'd be better off just adding Matrix to the HOB
on the tank?
The reason I want to reduce nitrates is because apparently dwarf anchor catfish need 12.5 ppm
or lower. 5-7 ppm
may not seem like much, but if my nitrates are, let's say 10 ppm
, just before a water change (10 gal
low-light planted), a 50% water change isn't going to lower nitrates much. If weekly 50% changes are only removing 2 ppm
, and >2 ppm
nitrates are produced in the tank per week, the level will creep up over time.
