finally rigged a system for removing red algae but its a two man op.

tanks are staying amazingly low on nitrates.


I wish I knew how to keep the Nitrates low.. I did a partial a few days
ago and IM back to 15 ppm..

I was told 'less than or equal to 20 ppm' was low enough. Why is 15 ppm too
high? I would think, with your canister type filter, 15 ppm would be pretty
good.

Does it stay at 15ppm? Or will it climb up on it's own? Have you tried
feeding less?

My 30 gal is almost completely filled with lr including the false back. The
nitrates stay at less than 15 ppm. No canister on that one.
