Hi all,
Mixed reef running at about 10.4 dKh and phosphates as measured by Hannah ULR are blinking 200. Redid test with half RODI water and results still at 200. Calcium measured high (>500 via Salifert) and I run AFR on a very low dose (not many hard corals to speak of). I have turf algae and GHA.
Decided to simply pause AFR and it dropped to 10.1 dKh over 3 days.
I am leaning towards using phosphate rx since I suspect GFO will be at capacity quite quickly (in any form) and expensive, and LaCl should help lower alk as well. I have read from @Thales it can be dosed in skimmer neck. Was considering a very conservative first dose of 5 drops, wait 24 hours, remeasure. Corals seem to growing or healthy as they have good tissue extension, and have been living with high phosphate for some time, so don't want to shock them.
Does this sound like an OK plan? Should I get a 5 micron sock just in case? My daily AFR dose is pretty low, 4 mL/day last I checked my dosing pump rate.
