So over the past few months I’ve been trying to get into SPS corals. As of now, some do ok and others slowly die. Not really sure why. I only had one alkalinity spike a month or so ago but that is now under control and my alkalinity is stable around 8.0. The spike was up to 9.5 over a day or so. For the most part my acros very slowly encrust but no new branches. A couple of the acros, 1 in particular was growing like crazy with new branches all over which are now slowly going off starting at the tips.
my parameters are as follows
No3 - 5
Alk- 8.0
Phosphate - .04 (stable for months)
Cal - 470 (also stable for months)
Salinity - 1.025-26
no clue what I’m doing wrong. I recently adjust my lights (48” aquatic life hybrid with dual hydra 26’s). My LED’s ramp up from 10am to 2 pm and ramp down at 6pm to midnight. Longer night time for blues. T5’s are only on from 1230pm - 4pm. This is peak PAR hours which give the top half on my tank 300 and the sand-bed just under 200. Once the T5’s go out my PAR drops by half. I’ve attached a photo of my light schedule and some of the acros with issues. All LPS do well. I’ve lost a couple which I believe is from the high PAR in my tank. My space invader pectinia is also slowly dying which started right after the alkalinity spike.
My system is a 120 gallon 4x2x2 with a 36 gallon sump. I run a doser at night time for calcium and alkalinity and I add aminos and phyto manual every other night. Any tips are appreciated. Not sure what to do. I tried trimming the dying branches on the Acros but it just starts on another branch. Again it’s not all of my SPS only a few. Others are slowly coloring up and encrusting the rock work.
