High pH 8.78

[eldiente]

I just installed my aquacontoller III and it says my pH is 8.79. One test kit reads around 8.2 and the other that I have is 8.4. The pH probe is suppossed to be calibrated at the factory but I think I need to re-calibrate it to make sure the reading is right. Have others had a problem with their probes being off and where should I look to get the 7.0 and 10.0 test solutions to calibrate it. thanks also if my pH is really that high should I be concerned and how do you lower it in a 250 Gallon system? thanks

Definitely calibrate... yes, get a 7 and a 10 to calibrate with. Your tank would be nuked at that point if it were true.

You can buy those solutions from any e-tailer.

Old batteries will also effect the reading. You might start there first.

u could use super buffer dkh by kent marine which will buffer down the ph. i didn't touch on the whole calibrate thing cause everyone else already got it.

Thanks I ordered some off of marine depot and i'll see what it really is. The unit plugs into the wall so batteries aren't an issue. You'd think they would ship it with some stuff to calibrate it with as I'm sure the package was jostled around in shipping. Oh well, I'll wait a few days and see, thanks for the info

Don't do anything until you know for a fact what the pH actually is. Have your LFS test a water sample as well.

My LFS doesnt' test water and I only have one in town, but I will calibrate it and see what it says first, thanks for the info.

Got a hobbyist in your area that can test it with their kit or probe? It is just good to get a second opinion before you do anything to your tank. And look at the livestock, as that is more important than the numbers anyway.

All I'm saying is don't over-react.

I am totally with Mark... let the tank tell you what is best!
