Wondering if I can get some guidance. For some reason I can seem to keep fish alive in my tank no matter what, yet inverts like featherdusters, blue leg crabs, astrea snails, copepods and amphipods all do good.
Tank was cycled and has been up for a couple months.
I thought perhaps the oxygen level is low but how do I test for this?
I've tested Ammonia, Nitrites, Nitrates, pH, SG
and everything checks out good. Running some carbon, Purigen and PhosGuard, so that should eliminate silicates and phosphates.
My tank is a 75 Gal
and I have 100lbs of live rock (nicely cured, covered in coralline) Filter is a fluval C4 (running media) Remora skimmer and 2 850GPH Aqueon powerheads. Lighting is a quad T5 fixture.
Appreciate any help!
