Hi all,
I have been reefing for about 8 years now. Current tank has been up and running for a little over 2 years. I had a tank crash due to a power failure last June and almost all coral died.
Tank parameters:
Tank: 110 gal (Red Sea Reefer 525 XL)
Skimmer: vertex omega 180i
Lights: 3 Radions running the AB schedule with very high blues and 20% whites
Pumps: 2 MP40’s running on reefcrest mode at 40%
Temp: 78-80
Alk: 9-10
Cal: 425-430 ppm
Mag: around 1300
Nitrates and phosphates near 0
Fish:
3 lyretail anthias
3 bartletts
1 foxface
1 Lamarck angel
1 naso tang
3 firefish
I never had too many issues growing acros in my previous tanks, but this tank seems to be giving me the most issues.
I have some sort of algae growing on my rocks which seems to be hindering sps growth. Over the past 9 months has been minimal. I think the algae might be preventing the coral from spreading.
Attaching a full tank shot.
But the strange thing is that some of the coral did t grow even half an inch over a 9 month period. Even though I am dosing 2 part at the same rate as I did earlier. I did notice a lot of spionid worms growing, will that be the culprit for alk and cal intake?
Attaching a full tank shot for reference

tried water changes and reducing photo period. Didn’t do a blackout yet, but willing to try that out as well, if required.
