Alright so a year ago I decided an attempt at sps corals . I've been reefing for about nine years. I have stuck with l p s and softies most of the time but now I set up an awesome 40 breeder and started trying SPS. The tank is approximately a year-and-a-half old and I've had SPS and there 4 about 9 months. The problems I'm running into is 4 of my sps stn from the base I couldn't tell if it was due to my flow (I accidentally set it for on/off every 6 minutes but I corrected it) or some other reason.
Everything has always been stable I test alk ph cal and mag every 3 days.
Alk 7.7-8.0
Cal 415-425
Ph 8.3-8.5
Mag- 1270-1400.
I run an ecotech at 20k for mid day 65 percent with 2 t5 for supplement
It's a bean animal overflow to a 29g sump. In the sump I run a reef octopus rodc 2500 for a return , cheats in fuge , and a skimz skimmer. According to my apex I haven't had any temp swings 79.7-80.5
I dip the corals before the go in with coral rx and inspect for pests periodically. To this date nothing. Please help me figure this out. Was it the flow that I fixed , is it my lighting or is it something else
