thanks guys
Did you add all together on a reactor or separated? I do not think you can mix these products together in one system. I suspect maybe you triggered a chemical reaction that added an element to your system that bothered coral. Gfo, al99, rowphos alk sr chemical products that works through a certain chemical reaction to do the function...

If that's what happen you need frequent wc to reduce whatever that is added to your system..
Also did you rinse these products before you used them?

Another data point here, since colors are fading it might be an indication of quick po4 reduction, maybe even down to zero in short time.
You might need to aid coral with some nutrient and reduce reactor flow a bit but carefully so not to increase no3 po4 too quick

I can not really see it from the upload water test results a couple of pages back but you have mention that the Al level is high already. I would expect the reason from the Al based absorber you have used. Under different circumstances and within a for saltwater aquarium common PH range they can leach Al. I can not say much about the product as I never used it but if that is the issue, some additional water changes might help if the affected corals are not damaged to much already.

Alex, are you aware of any po4 absorber that is not al based or does not leach? Just wondering if you are aware of a product...

I have not really worked with PO4 absorbers but there are basically two different types available, iron based and Al based. What I have said was referring to the Al based absorbers which can be problematic if directly used in saltwater but this might differ from product to product, who knows

That make perfect sense. Regular gfo are iron based and I believe the rowphos which the user used is al based.
Very helpful Alex thank you..always we learn from you

i think rowa is iron based, al99 is al based. Al99 must be use in a small water flow to make sure they don't move. I have done some water change recently, see if things can get better or not.

Thanks guys<3

Not really, stabile parameters are important now and all changes should be done very slow.
