The Issue:
Some of my sps (mostly montipora) has been turning white in random places. My Monti cap is turning white on the middle and around the edges. The other branching monti's have been turning white on the tips and bases. My Birdnest colony is turing white on the base and growing much slower than it was before. Coral growth has slowed since the move about a month and a half ago. There is also brown growing on the dead tips of the stated corals. Like is was burnt. I haven't really changed anything since i saw this happening. Other sps, Lps, and Zoas are still doing well and growing. The three clams also seem to be doing very well.
Parameters:
1.025
Cal 400-420
PH 8.0-8.2
Mag 1300
Phos 0 (API test kit, hard to tell)
Nitrate 0
Alk 5.3(tested at advanced Aqutics)
Up until 3 days ago, i was dosing B-Ionic.
30ml Alk and 30ml of Cal every other day. Since my Alk was so low, i switched to dosing 50ml of alk and 30ml cal every morning to raise the ALk.
My Lighting:
switched lights from 6x39 t5 4 a month ago.
36" Prestige LED, only keep two t5s on for 4 hours
(started at peak of 30% and slowly ramped them up to 45-50%)
9am 15% avg.
10am 25% avg.
1130am 35% avg.
1230 45% avg. t5s on
730pm 30% avg
830pm 20%
9pm 5%
930pm moonlights 1% all night
Here is before and after pic of monti cap. and other effected corals.
