Yes, inorganic Phosphate (orthophosphate) can be utilized by algae, bacteria, phosphate removers, etc. Inorganic cannot and cannot be tested for but can break down to form inorganic phosphate which will in turn be taken up by the above (almost as quickly as it is released). Greg

*edit:
I said inorganic twice. Meant organic the second time. Organic phosphate is bound within organisms or organic compounds and isn't free in the water column for algae, gfo, etc.

So I did a 25% WC and this brought po4 down to .08
That was yesterday. I check today and again it's back up to .16. I cleaned out my reactor full of hydroton and am preparing another WC. Why does the phosphate keep rising. I have three fish, no sand blow off rocks 2x a week and employ prodibio.

With the low bioload I'd be looking at your rock/sand. Moving the rock may have opened some new areas to increased flow which could now be purging. Prodibio might need some time to catch up.

Aquavitro fuel - their website says that it's a vitamin, amino acid, carbohydrate, vitamin and trace element supplement. This is going back to first year organic chem, but I didn't think phosphorous was a significant component of any of those molecules, they're predominantly made of H, O, C, N, and S. Though I suppose 'trace elements' leaves the door wide open for just about anything to be in there.
Unless there's something else in that product with phosphorous in it, I wouldn't suspect it would be the culprit.

Fuel has a substantial amount of cholera(bad spelling) when it breaks down and is not skimmed out would this not turn into po4
Good read on phosphates http://reefkeeping.com/issues/2006-09/rhf/
