I've been thinking about converting my 55 gallon into a heavily planted tank. I realize that I will require heavy lighting and a co2 system. My question concerns how you can control the PH level using co2.
Specifically, my tap water has a very high PH at 8.2. The KH and GH are also rather high. Its my understanding that co2 will lower the PH and that I can actually use co2 to control the PH.... by rigging up the system to maintain a 7.0 PH. Is that actually possible?
If the answer is yes... then what happens when I perform a 20% water change? Won't that create a temporary spike that will be a problem every time I do a water change?
