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

[Animal-Chin]

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...

I completely agree with the last 2 posts. Is anything actually wrong with your tank or are you chasing numbers?

I have had a few sps rtn on me,,, probably due to too much ALK at one time...

when I wake up in the morning and the pH is 7.6,,, I start to worry...

Ya with RTN it's hard to say. I've had it happen after a crazy alk swing (doser broke) and I've also had it just hit out of the blue.

and besides when you spend well over 1k on equipment you'd expect all of them to report the pH somewhat similar..

you really need to stop trying to justify a $1000 to get a common PH reading before you go crazy. your $1000 was spent on a lot of stuff not solely a PH probe made over seas for probably 12 cents, the rest of your apex is mainly what you have paid for (disgustingly overpriced IMO) but none the less I still bought one.

you're going to go crazy chasing a mythical 'perfect' number which even if you manage to hit with buffers and any other crap you wont be able to maintain anyways.

the RTN sucks but I doubt a slightly low ( hard to say is it even low? which testing method is actually correct? are any of them correct? all the end of the day they are all cheap methods) would be the sole cause and only effect a few, I assume everyone who has kept SPS for any length of time has had an STN/RTN experience.

Success,, Previous to the installation of the CO2 scrubber,, the pH would have low swings down to 7.6 and peak out at around 8.1....

Now with the scrubber it'll drop to 7.82 at night and quickly climb to 8.2 in the day..

I have stopped adding Seachem Balance to see how the scrubber does on it own, I'm guessing it'll perform the same,, just may peak a little later..

I had a huge pH issue years ago, I solved it by getting rid of my pH probe. No issues since. Unless there is a visible problem with the tank, I wouldn't worry about it. Last time I measured pH was 2004.
