well i finally finished my DIY CO2 system.
i used 2x 2-liter soda bottles, silicone tubing going straight through the bottle caps (sealed and cured with silicone sealant). the tubes go through individual check valves and then to a t-connector that connects to the main line going into the tank...which ends on a glass air stone.
i have some questions for ya:
1- i understand the addition of CO2 will lower my pH - i have moderately hard water with a pH of 7.5, how long can i expect the CO2 to drop my pH? will this drop be sudden (as to harm the fish) or occur slowly?
2- is it a better idea to change both bottles every 2 weeks, or change 1 bottle every week, alternating the bottles?
3- how long before i'm supposed to notice a difference in my plants? not really worried about getting crazy growth, but rather checking that it is working!
thanks!
