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

well I am,

at night my ph will drop to as low as 7.68, it'll max out only to about 8.06 in the day..

I have a skimmer, MP10, MP40, and a GYRE 150 kicking up waves,,
I have an air line plumbed into the MP10 to create fine bubles for 1 minute every 30 minutes.

I have 2 window fans exhausting out and 1 window open. So 24/7 the volume of air in my suite is probably cycled out 10 times or more a day.. (guess)...

going to try the CO2 scrubber solution. as demonstrated here

I have most of the hardware.
Just sourcing out the media now.

Hopefully will have it up and running in a few weeks.
In the meantime has anyone tried this before..

Interesting, I don't like my PH to fall below 8.0. usually runs 8.2 in the day. I do use a Aquavitro product called Balance occasionally when I see day readings below 8.0. This product is unique as it converts bicarbonate into carbonate. So it isn't just a PH buffer, which I don't use. Maybe see how it works for you?

seems interesting this balance you speak of :)
 

going to try other venues before I go chemical..

my current plan with the Co2 scrubber will be just like filter/skimmer maintenance...

I already have enough things to dose :(

pretty new
 

been researching this balance stuff,,
seems pretty new,, where did you source it out ?
and does it actually raise ph without mucking with alk ??

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.

3 electric ph probes...
 

purchased another ph probe today..

apex 8
seneye 8.34
etekcity 8.11


WTF ?

Do you run a refugium?

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.

Someone else posted Seneye results recently and his reading was higher than Apex too.

Did you try putting all 3 directly into a calibration fluid with a known pH after calibration? For example they should all read a pH of 10 in a pack of pH 10 calibration fluid.
