you replied to a similar one on AC.
its just basically a small trough with a valve that mounts upside down to catch the bubbles for "maximum CO2 diffusion/absorption". If anything I think itll stink being stagnant.
Its the part that suctions to the glass. I am trying to figure something out on a large scale ceramic diffuser. Itll be a while before I can afford the valves and regulators( my hvac ones are broke) for the pressurized but have my tanks already.
What do you mean a HOB will gas off the tank, the HOB will consume/gas off the co2 before it hits the water, what doesnt get gassed off isnt enough to do anything at all.
I jsut ripped my DIY apart and had it into the AC70 directly thru the top nipple and the intake tube itself. to be honest my plants are doing fine but my java ferns I got from fort are showing signs of new growth as in new plants that will detach and the main leaves are browning and or melting away to nothing
