right...yes, I let it sit overnight, both inside and outside the house...
inside the house aerated 12-14 hours later: 8.25
outside the house aerated 12-14 hours later: 8.27
non aerated inside the house after 24 hours: 8.11
non aerated outside the house after 24 hours: 8.13
this is what's bugging me...as you can see, from both aeration and non aeration tests, the change is very minimal if even noticeable - only noticeable because of digital meters...
I know aeration fixes my pH issue...now why in the heck will it not solve it in my tank, in other words, I have more than enough flow (fish only tank), no canopy, lights are 13" ABOVE top line of tank, fans, etc, etc...tank temp is 79...and I've removed ALL sand, and ALL rock and put in new aragonite dry sand...no changes.
it's as barebones as it gets - in other words, there is nothing I can possibly pinpoint or question that might be lowering my pH....only other things I have in place are a carbon chamber/reactor, phospahte chamber/reactor, nitrate sponge chamber/reactor - and I don't see how any of these three would have an effect on pH at all....
