I set up a new tank about a month ago and can't for the life of me figure out why it's consuming so much alkalinity.
The tank is 150g with a 35g sump. I previously had a 55g and the rock and corals from that went into this tank. I added 120lbs of new sand and a lot of new rock as well. None of the corals are big enough to explain the alkalinity consumption.
Alk is 8.15, calc is 420, mag is 1350, phosphates are .06, nitrates 5-10, and pH is around 8.
Without dosing, the tank is consuming about .45dkh per day. I'm dosing 120ml of soda ash at 1.5cups/gal to keep it from dropping.
What's going on here and how can I fix it?
