Been working diligently on getting my PO4 in check. Got a new skimmer pump, removed all the sandbed, sucked out all the detritus in the sump, etc. Also started biopellets and VSV again. I have been reading about lanthanum chloride dosing and PO4 reduction. It really works. I'm amazed.
Tested my PO4 this am after my 2nd dose of LaCl3 and it is now .03. That's after 2 diluted doses of LaCl3 at 2.5 ml / L for 150 gallons. I'm still quite impressed. In 3 days it brought my PO4 down to .03 from .49 after 2 doses. I'll keep an eye on it, because I'm sure I'll have some PO4 leaching from my LR, but I don't mind another dose or two. The biopellets and GFO should help as well.
I am about finished with my LED fixture. I re-did the lights and added 4 LED spot lights (2 PAR38 and 2 PAR30). I'll post some updated pictures once I get the rest of the parts to complete the fixture.
I have been adding zoas and LPS again now that my PO4 is going down. I'll order a box of SPS in a few weeks after the holidays.
