Hi all, I'm new to the forum but not new to reefing (almost 10 years in the hobby). So I have a 25g IM Lagoon in my living room. This is also the room where we hang out in most of the day. My issue is that I can't seem to get my pH any higher than 8 sometimes 7.9 on most days. Given the small size of the tank it greatly varies based on amount of people in the house if I open windows or if we're away from home for a few days. I know about all the tricks in trying to keep windows open (winter here) or airline tubing outside to skimmer (unable to do that) but was wondering on other methods. Kalk dosing? So currently i'm using the triton method. Have about 8-9 acros in there and some lps. Alk is around 8. My problem is that every time i have these pH swings the alk follows as the corals aren't using they loose color or get some tissue. Usually i'm able to get them back with everyday testing and adjustment of the doser. Also my growth rates are almost non existent because i'm constantly having this ups and downs with maintaining steady alk and ph levels (all other parameters are ok). Would kalk dosing help to buffer ph a bit better? maybe a bit every morning? I used to run a kalk stirrer on my old 75g dominant tank with good results but that talk was also in the basement where people weren't all the time. Anyway any ideas are greatly appreciated.
