What is this gooey stuff?

[REEFONE]

I've had this stuff for a while. It grows on any dead piece of coral and keeps my corals from growing over it. I have to use a turkey baster a couple times a week to get it off. I do 20% water changes weekly. I'm thinking it is a possible phosphate problem due to a bad batch of water from my RO/DI. I need to order new filters. I've been using RO/DI water from another source in the mean time. My tank parameters are below:

S.G. - 1.026
Temp. - 77-79
NO3 - 0
NH4 - 0
pH - 8.05-8.12
PO4 - ?

I ordered a phosphate reactor and rowaphos to hopefully solve the problem. Just was wondering if someone could identify this stuff for me and let me know the possible causes. Thanks.

Most likely chrysophytes as detailed in this thread.

Looks like cyano to me. You are going to probably have to reduce your lighting for a couple of weeks to get rid of it, if you haven't already.
