Hey guys,
Just a quick question here.
My fish room is setup using sponge filters, and as such, I am battling high pH problems due to the gassing off of co2 from my water. I'm currently trying to lower it via peat, which has worked a little bit...I think...
Anyway, my question is regarding measuring pH.
I have found using the drops (specifically, API) is yielding me a wildly different reading than my pH meter.
First off, I don't like my pH meter and don't trust it (because I have to recalibrate it EVERY time) - but after recalibrating it, it SHOULD be accurate.
Using the liquid test kits, I find I have a MUCH lower pH level. I am curious if this is due to the process in which I mix (shake, invert) the reagents in that co2 is added, therefore lowering the test result.
Here are some test results I am dealing with right now:
With pH meter:
Tap water: normal pH 7.6, after gassing off: 8.1/8.2
RO w/peat: 7.2
With liquid test:
Tap water: normal pH 7.6, after gassing off: 7.4
RO w/peat: 6.4
What should I be trusting here? Or should I just invest in a high quality pH meter and forget this madness?
