Well.... I have been having serious pH issues. The wife likes the house at a nice 72, and because of that, the doors have been shut tight for the past several weeks. I asked my wife to stop exhaling CO2, she did not like that So, I decided to pull my skimmer air from outside. Others have said that it didn't make a big difference, but we shall see. My pH had been hitting 7.6 over night... Below is a graph of my pH over the past 10 days. Can you tell what day we were out of the house all day? It hit 8.15!!! I started pulling outside air Monday night, and you can see the instant effect on pH... Also, I have not run the lights since I received several new fish yesterday... I can't wait until the lights come on today to see what the pH does then. I am hoping for at least 8.1 or even 8.2... After that, I will probably fire up my kalk reactor again...
Any other ideas besides a CO2 scrubber? Too much maintenance and the media gets expensive!
