It's a 100 gallon that was FOWLR that I've converted to reef with 4 frags (2 zoa, 1 duncan, 1 japanese nepthea).
My DI went out and started letting silica through, so it has been 1.5 weeks since my water change. I also ran out of GFO, added the carbon/GFO reactor about 2 weeks ago as well.
My shipment of new RODI stuff and GFO are arriving this evening. I'm also picking up something to address the Mag being low this evening.
Sg = 1.0265
pH = 8.2
Alk = 9
Calc = 500
Mag = 1350
PO4 = 0.03
NO3 = 0.1
I can start making more water tonight, have the 35 gallons ready by Friday night, but will be out of town and not able to perform the water change until Sunday. The issue is that the GHA is growing crazy fast. I manually removed almost all of it Sunday and it's already regrown in some areas with strands maybe 1 inch long. If I wait until Sunday I will have to manually scrub all of the rock again most likely, any there will just overall be more GHA to overcome.
My thought is that the PO4 will go back to 0 once I add the GFO and I'm not feeding hardly anything so my nutrients "should" stay manageable for 14 days, so does it make more sense to dose the fluconazole now before the GHA has a chance to regrow instead of waiting until Sunday to do a ~30% water change that will really only bring my NO3 down a little?
