What do you think has contributed most to the PE
A couple things could be possible, but I am not fore sure. Help me to figure it out.
1. Water parameters become very stable after Alkalinity correction cycle.
KH = 7.6 dkh, Ca = 410, Mg = 1410, K+ = 380, NO3 =0.25ppm, PO4 = 0.01ppm
2. I did try to kill bad crab (kill 4) hind in SPS colonies as much as I can before I leave home.
3. No hand in tank for a week!? My wife reject to do anything if she have to touch water.
4. Two old T5 tubes (out of 8) replaced.
5. I gave away my anemone to someone just before I leave home.
I would think it just naturally #1 contribute it, but maybe #5 help as well!?
PE is even longer during light off, BTW.
