yest water that comes into RO unit to see if Phos is high.
You can reduce with either chemiPure elite pouch in the sump or addition of Granular ferris oxide (GFO) in a nylon pouch into the sump- just use a couple of teaspoons as GFO is strong
Daily 2 gallon water changes for 10-14 days should also offer reduction as well as rinsing frozen foods and if using Reef Roids for coral- Feed them mysis and stop the roids which raises po4 levels
