Is it possible and how ... ?
I have 4 low tech planted 10 gallon shrimp tanks. All are sitting on a large 2 tier table. The plants are doing and growing alright even though it's on a slow grow side.
I'd like to add DIY CO2 for them but I don't want to have 4 different set up of a bunch of plastic soda bottles sitting all over the place, specially out in the open.
Is it possible to build 1 large set up of DIY Co2, then distribute them evenly to all 4 tanks?
If yes, please show me how. If no, would you tell me why.
I searched the forum to see it anyone had any idea how this done to no avail.
Thanks in advance.
