Has anyone had any experience with nitrate reductors? I see Aqua Medic do a Nitratereductor 400 which uses deniballs and a Sulphur Reactor which uses sulphur beads. Can someone comment on whether they are any good and which type is better?
However I'm sure they work ok, it's only adding a band aid to the problem you have. Need to find the source of the no3 and cure the problem rather than just patching it up for a temp fix. List your set up and lets see what we can do to help out.
