Has anyone had an issue with their pH because of the house? I had a leak a few months ago and started to see alot of water marks around the house. After trying multiple different things to keep pH from dropping I've came to the realization I must add balance by aquavitro every other day. I've tried air pumps and running chaeto with no luck. Alk stays between 10-12dkh cal 440. It's a 21G cube reef with inverts and coral. I'm hoping this post either helps others dealing with moisture problems or maybe someone has an answer to my problem. Thanks reefers!!
