Hello,
Controversial topic but I'm struggling with my SPS dominated tank.
Background:
Running for 3 years
125G with sump : 5"*2"*2"
Flow: 2 XF350 + 2 MP40 + 2 Jebao 4000gpd ( about 50-80% for all)
Water change : 10-15% weekly( upped to 30%, 4 times during the same week when multiple RTN have been observed; every parameter was kept identical)
Balling: 3 Part sodium hydroxide
Lighting: 5 Hydra 26HD +2 ATI Blue plus (roughly 700 - 400 - 250 top to bottom) since the start
Parameters: Kh8, CA 400, MG1350, NO3 5, PO4 0.08 / ICP done usually monthly/2month, nothing has mostly changed in the parameters since the start of the tank. Another ICP send yesterday (will update results)
-Running constantly UV and GAC(change every 2 weeks)
Added 2 bags of cuprisorb for 2 weeks already
-Every pump and magnet checked
-Skimmer outside intake through GAC
Recent change in the last 2 month:
-4 pound of live rock that's been in another tank for 4 month(now taken off)
-Reefmat 1200( taken off for 1 week)
-Salt from Fauna Marin to Red Sea blue bucket
-Acropower dosing daily 6ml instead of +/-20ml per week manually
-No coral/fish added
Description of the issue:
-Acropora are browning/getting lighter
-RTN/STN from base or tips
-Mostly start recessing on the encrusting then progress quickly (week or so)
-Serms to be affecting Tenuis first(1month), now going to donei and randomly
-Larger colony blasted with PAR are growing as usual, seems to be lighter than it was
-Polyp are extended as usual, affected or not by the progressing bleached area
-Parameters are and we're always kept the same, despite installing the reefmat. I did feed heavily to keep the nutrient the same.
-Dip show no flatworms at all
-Check during the night for any black bug
In the end, I've turned around the issue and i can't understand what is happening.
I've read about bacterial issue, for which I've ordered chemiclean (waiting), i also have ciproflaxin but I always take extra precautions about using any chemical in the tank.
The tank was always thriving, coral growing like crazy and colored up, i keep the method simple, balling, weekly water change, and stability.
I see most probably people will tick on the reefmat, i can agree but I can see most coral dying when showing for some, no sign of stress at all.
Time for the pictures, sorry for the really bad last quality, i don't feel brave enough to take the DSLR and face the reality.
Many thanks for anyone trying to understand and progress on that!
