Can't seem to get my Alk up?

[rtoris288]

I'm mid cycling (nitrites near zero, nitrates coming down) any only have my clean up crew and a few frags in the tank. Live sand/chaeto in the sump with a skimmer running. Just did a 10% water change over the weekend with Red Sea Coral Pro that helped but started dropping again. Been dosing 2 part as well (18ml Alk) daily in my reefer 250. Any tips?

For 65ish gallons of water I consider 48 mL of each part (or 93 of sodium bicarb if you don't use soda ash) to be a moderate daily maintenance dose, with more if you are trying to raise it. Assuming you aren't precipitating anywhere add more.

Just curious as to why you’re dosing a tank that’s mid cycle? I would also recommend no water changes until you’re zero nitrItes and ammonia. Once your solid with NitrAtes, you can start doing water changes.
