I'll keep all my opinions to myself. It's obvious from the evidence provided here thar nitrite is a toxic substance. I'll let the chemists decide how much hurts which thing or not. All my tanks have been exclusively on large high flow algea scrubbers. Algea directly process ammonia and bypass almost all the cycling issue. I realize I'm a dinosaur in this age but I do know what works. Like or not. I really just want that ki d of discussion. It's poison but it's not. That's what today proved. I resent being talked down to. I think most people do. I feel the chemical make up and it's reaction with other items discussed in links makes my point though. My stance simply was it's a contributor to stress. I stand by that. The proof is in this forum. No link or google. Just a fact. Enough of that. Have a nice evening. No proof required.This is a chemistry forum. The reason for its existence is to discuss reef tank chemistry. If a claim is made, asking for actual evidence is not an affront, it's a necessity.
