I got some assistance in battling the algae. The GKM has been running for 3 days now and honestly it's looking much much better. I also finished dosing H₂O₂, at the rate of 1ml/10G for a period of 5 days.
My softies look stressed out and some of them arent opening well. The Zoas and Rhodactis arent opening fully and the Euphyllia is still pretty much fully retracted. That said, I did notice this last night:
It would appear the Euphyllia is splitting from 2 heads in to 4 heads. I'm not sure if that's what is stressing it out as well or otherwise caused it to drop polyps but combined with the dinos covering it, the H₂O₂ dosing and the filefish nibbling on it 2 weeks ago, I think it's safe to say it's going through a rough time. I hope the coral additives and food can give it the strength it needs to pull through. You can also see the sand bed and the rock is looking much better and most of the dinos are almost gone. Thanks a lot to everyone who reached out to me with tips and advice on how to battle them!
On a sidenote, I tested water again, mid-week this time, and a full cycle:
I'm upping my All for Reef daily dosage as it appears my alk, calc and mag are getting consumed faster than I'm currently dosing for. That Kamoer X1 came just at the right time.
I'll wait a little bit with the NitroPhos Minus until the algae problem is completely sorted.
