Have you tested your normal tap water to check for high pH? Our tap water has a terribly high pH is why I am asking. Just trying to rule out something in your tank being the cause.

what's your substrate and do you have any rocks in the tank? is it the one in your avatar? if so, what's that back ground made of?

if the avatar tank is the one you are talking about I looked at your rocks, they all look fine so I doubt it would be that.

Just about the only way the pH can go up is by carbonates dissolving from rocks or substrate. You can test them with acid to see which fizzes.

If anything with time the pH should lower some unless you have something going on. I would wait it out and keep testing the water. Not once an hour or nothing like that...

mmm no idea, just throwing this out there but could there have been some residue of a cleaner or something that could cause the ph to go up. I don't even know if soap or something would have an effect of ph.

Demon, my PH out of the tap is also extremely high - maxes out on the test strips!

Is there anything you do other than letting it sit to lower the PH.

Does a high PH inhibit you much in terms of fauna options (fish, shrimp, etc.)?
