Hi aquaman
I had a group of 10 that I grew up in a 75 gal bb. My TDS is 225-8 (I also live in FL). I also aged/heated my water and also did 80% wc daily. I also fed flake, fdbw, and beef heart. I had some that didn’t grow to their full potential but I attribute it to the fact that that the females who laid eggs were the ones that stayed at the size they were when they started laying eggs. Just wondering if this may have happened in your experience. I should add that my husband occasionally calls me Captain Obvious. Ha ha
While we have a lot of things in common, I aerated to prevent micro bubbles. My pH doesn’t swing whether aerated or not. Not sure if this will help, but thought I’d throw it out there. Good luck in whatever you decide to do.
