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.
I went from 5 ppm to 15 ppm in roughly 10 days. I've tried less feedings
(every other day) I've also tried more frequent partials and still the
nitrates climb.

I'm not sure there is anything wrong with that. I don't even know how you
could test so accurately. I think if you have any fish and you are feeding
them you're going to have some nitrates. I was told to do my changes at 20
ppm.
Are you feeding your invertebrates separate from you fish?
