I am 100% with you guys in that maintaining low nitrate levels is necessary in maintaining optimal health for fish and inverts. I was in no way suggesting 160 ppm
nitrate is acceptable, desirable, or in the best interest of any fish or invert (all 3 of my reef tanks are kept between 0-3 ppm
nitrate through macroalgae refugiums).
I was just questioning whether anyone can be sure that excessive nitrates are going to definately kill fish. To be quite honest with you, I don't think the triggers, groupers, and lionfish in the display tanks at the LFS
(previously mentioned) care whether the nitrates are 0 ppm
or 150 ppm
, as long as they are being fed. But I'll also admit that triggers, groupers, and lions are very hardy fish. JMHO
Thank you for your inputs.
