Natural Co2 Entrapment (Problem??....Help Please.))
I have been rather busy of late, and only noticed an interesting new development in my aquarium this evening. My first (and only) aquarium is a 20 gallon planted Southeast Asian biotope, I am using a Hagen Canister Co2 reactor. Using my own formula, the Co2 production is sustained for 2.5 weeks-- the bubbles escape the reactor and dissipate through the surface. Now the bubbles are prevented from escaping through the surface due to the large lily pad that has taken up much space in the top of my tank. The carbon dioxide is forming a very large bubble underneath the lily pad, this has been going on for a few days, I assume. Could the enormous Co2 bubble cause unpleasant changes in p.h,? Should I move the lily pad to let the bubble escape? Is this a potential danger for my fish and plants??
