HELP!!!!

[BigO]

Ok so I got it figured out, it was my water source! Question, how do I go about doing water changes now that I got my water problem solved? I would like my phosphates between .03-.05 but they are all the way on .16. Should I do a 20% water change or would that be maybe be too much of a change, and end up hurting my sps because of too big of a drop in phosphates too fast? Or should I do a 10% every 72 hours until phosphates drop to where I want them?

I find that water changes do little to reduce Phosphates.

So are you defining "source water" as the water going into your RODI system or are you detecting phosphates on the output of your RODI system?

Output, I to change out ro membrane and the rest of the filtration on my rodi, soon as I did that… bingo.

I had freshly mixed water ready to go in the aquarium and I tested for phosphates on fresh water that had not even been in the aquarium and the water had high phosphates, I then tested the water after changing everything on the rodi system and the phosphate reading was virtually 0

But how about sps dominant tanks? High level phosphates are a nono.
