1.025 SG NSW (no change, overzealous skimmer counterbalanced lowered ATO level)
8.3 pH
25.9 C
3.0 Meq / 8.4 dKH -- adjust doser down -12.5% (8 to 7)
500 Ca ppm -- adjust doser down -10% (10 to 9)
1440 Mg ppm -- I intentionally double dosed and didn't go up. I suspect mangroves sucked it up.
0.03 ppm PO4
< 1 ppm NO3
I have been able to keep the parameters, including temp, pretty much locked in for more than a month. The growth is really noticeable. The good clean water has been bad for my green open brain (trachyphyllia geoffroyi) which perished this week after a long slow death. Nothing I did, except for failing to do water changes, ever seemed to make it happy since it started to go down hill almost a year ago. It just slowly died, bit by bit. This week the hermit crabs finished it off. Every other coral, except my one ricordia, has been giddy with delight at the water conditions and feeding regimen. This has made me wonder though if I am trying too hard to keep phosphates low. Perhaps 0.1 PO4 ppm is a sufficient goal and I should cut back on GFO and phosguard.
