My nitrates run normally 10 - 15 ppm. I do 1/3 partial water changes
roughly every 25 - 30 days. Today I checked my levels and I'm at 20 ppm.
This is just after i did my Partial WC
Other then water changes how can I reduce my nitrates. I've tried in the
past adding macro algae, but the bristle star fish also found it and made
a meal out of it, so that didn't work. My tank: 75 gal FOWLR 4" DSB 85
lbs LR Canister filtration, Protein skimmer.
Thanks

I've got the same setup with my 45 gal tank.

On recommendation from someone in this group I added LR to my 45 gal. (There
must be at least 140 lbs of LR) The results have been good. I'd say I'm
changing my water now about half of what I was changing it. About 5 gal a
week. If my nitrates are elevated I'll skip feeding my fish for a night and
check it again in the morning. Usually the nitrates will be lower. The LR
seems to be doing the trick.
