Dilema - Need Help

[Nemain]

I just did all the cursed water tests; of course nitrates were a little high, amonia was a little high not sure why, but again, just slightly raised), what worrys me is that the PH is at 7.5ish from its normal 8.2 =(

Could it be that raising the temp in my house to help keeping the heat in all the buckets added that much CO2 into my air and dropped the PH? Or is there something else that could be causing it?

Any help would be appreciated.

I would rather try to figure out the problem before I start dosing anything.

Thanks again,

Beth
