Tricks for growing out zoa frags

[Baldy]

water params are good. 0 nitrates, 0.03 phos, 430 clac, 8 alk, 1300 mg, 1.025sg, 79C temp. no swings in temp, pH makes a daily trip from 7.8-7.9 in the morning to 8.0 in the pm. i have chaeto in the sump on a reverse light cycle so im not sure how else to stop that from happening.

i drip acclimate for about an hour. ive just recently started using revive as well, and the 1 zoa frag ive used that on is holding ok.
