Ok i have dosed my tank to bring up my Alk from 8 dkh to 8.6dkh. I like this range because all corals look their best to me. Now that i have accomplished that i will start dosing BRS 2 part because i also have my Calcium where i want it.

So i have been testing Alk everyday since i raised it to 8.6 to get a baseline of how much Alk my tank uses in 1 day but finding this hard to do and here is why.

Sunday- Raised Alk to 8.6. Monday Tested Alk-8.6 Tuesday Alk-8.7 Wednesday Alk 8.6 and Thursday Alk-8.7. With these readings it is virtually impossible to see what my consumption of ALK is.

When i test i use the same equipment for each test. Use a timer so i'm doing everything within the sametime. I clean everything good with RODI water when tests are complete. Not really sure how i'm going to dose without knowing what my tank uses.

I very much doubt one day miraculously their is 1 dkh more of Alk without dosing it.

How big is your tank? How many stony corals do you have in there? How large are they? You may just not used anything perceptible on the meter. Which obviously has a little plus minus range to it.

I have about 35 corals in a 120 gallon. Mix of zoas, softies, LPS and SPS. The only SPS i have is a Purple Monti Cap, Orange Setosa, Forest Fire Digita, Forest Fire Montipora, Jack o Lantern Lepto, Deep Space Psammocora and a Ponape Birdsnest

If they're just frags and your tank isn't seasoned, you might not be using much Alk at all at this point.

There are people out there that don't dose at all, and just do constant water changes.

Trust your readings and be happy you have a stable system. Keep up your water change regiment and test weekly.

If the kit is showing results that are that stable, I agree that the consumption might be minimal at this point. I'd continue testing once a week or so. The test kit might have a problem, so getting a second opinion might be useful.
