Thanks for feedback. Very helpful!I've been supplementing both tanks with chelated iron. Probably not necessary for this tank as you say, but I have so much of the stuff I might as well use it.
In my smaller tank I start running into iron issues immediately if I don't supplement. The floaters get pale and grow to only a fraction of the size, if they grow at all. I noticed it also helps keep my crypts looking a bit more red.
