Oh hey, I forgot to thank you for the link and the info! THANKS!! I'm just surprised that doing half water changes on he aquarium didn't rais the ph! Like I said before the Ph coming out of the tap the tap is higher! Now I have a question about how Nitrites and Nitrates affect ph but I think I should probably post that on the Filtration & Water Quality forum! I didn't see that forum before!! duh!
