I've always used the same brand GAC
, so I'm now thinking it's the Poly-Filter. I don't think a small amount of trapped CO2
(thanks for the info Steve-S) is making that big a difference in a 55gal...
Poly-Filters do mention on the package the possibility of them dropping PH

That would be great Steve, if they don't respond promptly I'll shoot them an e-mail also.

is alittle lower than normal but decent~8.1, I did a small PWC
last night. Thanks again guys.
