Let me see whati can do for pics Catherine.
Tony: I have used the salifert and the api both getting the same. I know i was a little skeptical as we'll but i think the 8 inches of sand is finally doing its part.
The po4 i don't have one of the "fancy smansy test things like you
So us regular folks just have to use salifert...lol
So no i don't trust it as i had that issue with the RO/Di not working properly and had the algae bloom form you know where as my tds was anywhere from 40-80. So i have a feeling the po4 is leaching out of my sand and rock

I am using reefpur phosure for removal. Although i have tried every brand out there and none of them seem to really work which is where the sand and rock leaching it i think comes in.
I don't know what the answer is. If its the phosphate what do i do now? As i don't want to lose the corals but the only other tank i have to put them in has the same issues with the water so that isn't going to help.
