low pH ? - chilax they say, don't worry they say..

[Myka]

Yeah that's a really big swing. It's not that either number is bad but the swing isn't ideal. Are you actually seeing any issues stemming from this?

Before you bother with a co2 scrubber, do the co2 test described here when the pH is 7.68 and see if it really is co2 that is causing the problem.

Definitely a WTF! Assuming they are all calibrated correctly, you may be chasing a phantom number. J & L sells balance. Jeff recommended it to me as it works differently from a PH buffer.

do they still carry ??? can't find it on their website.

Are you ph swings effecting things? I never test my ph as I dose alk that keeps it pretty constant but if there is one thing I've found during this hobby, if it aint broke don't try and fix it. Even my recent carbon dosing experiment was a bad experience. If your coral are dying or something due to PH issues that's one thing but if you're just trying to hit a number for numbers sake I'd not bother.

Just my 2 cents.

I don't recall the last time I checked pH or worried about it.... my critters are fine. The less instrumentation in my tank, the better I like it. If something is horribly off, I can usually tell by a visual of how the living things in my tank are behaving. The only thing I check regularly is salinity, when I do water changes. I used to check Alk & it was always chronically low (according to the test kit), but I don't do that any more either & fish look good, coral is growing...
