Brittle stars don't eat macroalgae.

Your canister filter is contributing to your
nitrates. You could convert it into a denitrier by
restricting the output.

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
