430 ppm Ca would be better for that alk level.
Yeah, I should have looked at Andy's site before saying that.
I checked the Alk
this morning after adding 2 tsp of Reef Builder yesterday. It hadn't risen a bit, still at 8.2 DKH
. I believe James is correct in that the Reef Builder seems to be weak for some reason. For whatever reason, it can't seem to raise the Alk
beyond 8 DKH
So, I went ahead and used some baking soda I had on hand this morning to adjust the Alk
since the Reef Builder is not doing the job any longer. I checked the Alk
about 4 hours after the addition and it was up to 10.2 DKH
. I'll check it again tomorrow (24 hours after the dose) and see if is above 8 DKH
I'll check the Mg
level as well tomorrow to see what is going on there. Luckily, Oceanic salt has a Mg
level that is extraordinarily high. Around ~1350 out of the box. Hopefully, it is still high enough...
