Interesting to see that alk didn't go down the day after doing a water change. Measured ~3hours after the change so maybe insufficient mixing time? or the change stops/slows growth rate from the shock/change?
prior calculations showed the tank using about 0.75-0.8 dkh/alk a day and 1/2cup of alk solution bringing tank up roughly 1.6 dkh.
this week from Mon-Tues (12th-13th) alk dropped ~ 1.7dkh if accounting for adding 1/4 cup alk = 0.8 dkh
tues-wed alk dropped 0.7dkh with adding 1/2 cup alk =1.6 dkh
so the mon-tues drop is kinda high but maybe the alk dipping into the 7s on Tuesday and slows growth/uptake from tues-wed? gotta keep testing to get more accurate idea of alk use.
calcium/ magnesium not really dropping at fast enough rate to really worry about now. A few more weeks of dialing alk in and get it on auto dosing. Figure out Ca/Mg then
Rocks on right of tank going soon either through fellow member or LFS for credit if need be. The dry rock I picked up has been curing in a bucket for about a month now. Ready to get rid of the Paly rock for more lps growth room and pick up a soft coral with more movement in the current to fill in next to the anemone. hopefully have room to slide the anemone rock/pillar to the right too, away from the left/monti side. Anemone is almost reaching the Monti cap now.
