I am currently using the stock Fluval 88G CO2 system and observe a good portion of the bubbles reaching the surface (uses a ceramic disk). I have looked at several other methods of diffusing CO2 and am curious what other people have found to work best in terms of efficiency.
The method must be...
less than $50
aesthetic
no ceramic disks or ladders
I am considering...
power head
co2 reactor (not too sure whats involved with this?)
placing the co2 output near my HOB filter intake?
Any advice or suggestions is greatly appreciated. Thanks for reading!
