Update - 9/3.
I'm at a loss here. Really starting to get discouraged. I can't find an answer what's causing this.
8/20 - Started running filter socks changed out twice per day. Had an accident with the return pump - dropped salinity to 34 PPT (1.026).
8/24 - Noticed the "Emmett's Blue Polyp Purple Tort was losing it's flesh. Took the tweezers and superglue to as many of the snail tubes as I could see and get too.
8/25 - Alk 9.2, Ca 430, Mg 1360
8/26 - The tort just got worse and worse. Stopped all 2 part dosing (was at 125 ml of 2 part)
8/29 - Down to 9 hours of total photoperiod with a ramp up of 2 hours (instead of 4) and a ramp down of 2 hours (instead of 4)
8/30 - Switched salts from IO Reef Crystals to normal red sea sea salt (for lower alk). Performed a 50 gallon water change with 36 PPT (1.028) water. Salinity in the tank back to 35.5 PPT or 1.027
8/31 - testing: 6.4 Alk, 430 PPM Ca, 1280 Mg. Started the dosers back up. Instead of dosing Alk at Night and Ca in the day, I re-programed the apex to dose Alk on every hour, Ca 15 minutes into the hour, and Mg 30 minutes into the hour. It takes 10 minutes for the dose to disperse throughout the sump (I can see the delay on my pH probe). Dosing 100 Ml of Alk and Ca. Dosing 25 ml of Mg.
9/2 Testing: 6.7 Alk, 460 PPM Ca, 1320 Mg.
I still see snail tubes and mucus nets in my tank. I also see several aiptasia that really annoy me. Nothing close to corals yet though.
Emmett's Blue Polyp Purple Tort is pretty much gone. There's a bit still left
The red dragon's damage is getting worse
The ultimate purple monster is also showing signs of sloughing
The undata appears as if its coming back
