How much alk does your tank consume daily?

mooputingtong · Oct 28, 2020

My tank is fairly new with few frags and still no growth of coraline algae. I Dose about 3ml of red sea foundation b alk daily and that still lowers about little less than 1.0 dkh per week. So i guess i will need to raise my alk to keep it no lower than 8.0 dkh. How much dkh does ur tank consumes daily? and how much 3ml of alk do you dose daily?

ATO, saturated kalk replaces whatever evaps. I don't keep track.

Currently using Fritz RPM alkalinity part 1 and dosing 30ml a day. Currently stable at 9dkh and can't complain. I've used red seas alk and had no bad reviews on that. More bang for buck with the Fritz IMO.

Hi All
Info without system volumes is not helpful. My system at 65 gallons uses 15 to 20 ml all for reef. Running for 6 years as a mixed reef.

59.4 ml BRS on my Red Sea 350. the tank is 3 months old with corals moved from my RS 170. Bare bottom with Coraline algae entrusted. I will consider mine only a medium load only. This kept my PH @8.35 ALK 8.7 CaL 440 Mg 1400.
