The pH levels of my tank fluctuate pretty heavily between day and night. I've read several websites and books which say that this is normal in tanks but I also understand that in general it's best to keep pH level (as well as other params) as stable as possible.
One method I read was to have a fuge lit at hours opposite to when the main tank is lit. I do have a fuge which contains chaeto, well lit and grows pretty well. So far my attempts to have this lit only at night are still in the trial and error phases, but since it's a pretty small fuge, I don't get the sense that this alone would control the fluctuation.
Just for ideas, I'd like to know other methods that people use to stabilize the pH level of their tank between day and night. Anybody willing to share?
