Phosphate levels

That's not bad at all. Looks like diatoms to me. Need to make sure your DI resin is good and is packed in well so no channel is occurring. Diatoms like silicates which can come from Tap water that makes it through your RO membranes and DI if not packed in well or is exhausted.

Take a picture of your RO/DI unit. There are some funky ones out there but a majority of them are pretty universal. I get all my prefilters and DI from Bulkreef supply or Spectrapure and RO membranes from Spectrapure.

You wont know your GFO is depleted with out testing the water going into the reactor and testing the water coming out of the reactor. If they are the same then the GFO is exhausted. If the water coming out is lower then it's still working. Make sure the GFO has a nice slow rumbling on the top.

Thanks for the feedback Jason - i agree with you, i think its just simply brown aglae diatoms, however in the other picture i showed, it looks like cyano in my refugium and is taking over the cheato

Pull the chaeto out and rinse with water from a water change. I wouldn't shake it off in the refugium.
