Yes it does Aqua. The parva may not last too much longer with me. It just isn't looking like I want. I'll probably keep spreading out my AR mini as it grows. It makes a beautiful carpet and the Corys love swimming into the leaves.
Janis, Aqua, I did the tests just now and the half dose test didn't do as I expected. The actual color was about the same as the full strength normal test, but the opaqueness or intensity was just less. BTW, the NO3 is down to 15 and the PO4 is up to a solid 2.0. Got a concern though, my KH is now down to between 2 & 3. I'd really like it at 4 to 5. Would it help the plants to add a little Bicarb? or Epsom Salt? OS.
