Greetings,
I have been fighting a hair algae issue over the last few months and as one of the additions I have started using a phosphate removal media.
I started using a smaller dose about 2 weeks ago and saw no improvement with the HA, so last week I added the full container to the reactor (and added a small ball valve to slow flow through it, slower=better was my understanding). I have a total system volume of 400 gallons and the PhosLoc container says "treats 300 gallons", so I was still under dosage.
I noticed last night that several of my corals, particullarly a pink Millie and green Tenius, have faded in color and worse some others have bleached out in sections and some have STN'd all together.
Could the reduction of phosphates or the chemical treatment itself be the cause of this? Would it be attributed to changes in water chemistry brought about the use of thr phosphate removal media?
Other random occurances to the tank over the last week (could be contributing factors):
pH controller went out on Ca Reactor - down for 5 days (Ca level last night 370)
Added dolomite to Ca reactor to help maintain Mg levels.
Tested Mg level last night - down to 1050.
Cleaned light pendants over tank (more light = bleached/burned?)
Added algae scrubber (20 gallon with 4 inch DSB and macro).
Any help would be appreciated.
Thanks
Chris
