Good to know about the EXCEL.. I will certainly look into that. I will probably keep the meter though, I am an engineering guy and I love information and monitoring so im curious about the CO2 cycle in the tank. Also, I dont have enough experience with keeping live plants and having those extra kits that can tell me whats going on with my water has really helped recently. I will increase water changes though because I fell behind on them.
I already knew the light would throw the tank at least a little, Some leaves have gotten a little lighter on the anubias, so im also monitoring to make sure the new intensity isn't burning them. and reduced the light cycle to 8 hours. Are there any CO2 regulating methods that are cheaper than getting a regulator? Perhaps a guide on how to DIY rig a regulator?
Other members who dabble in CO2 will have to answer you. I have never bothered with it because I recognize the natural CO2 and it balances my light. I stay with natural or low-tech systems because the fish are primary, the plants just have to fit in.
