My first question is why do you have a BTA in a HT? Their pretty much bullet proof from my understanding. Second, what kind of lighting? I would think if you were running halides or led you would need to light acclimate, maybe multiple t-5's.
As far as a zoo transplant goes, I don't think it is necessary. Only in extreme circumstances would this need to be done.
I would test po4. Tapwater usually has a lot. Not good for nem. I say get it in ur display, get the lights on it, ad let it do its thang.
