Should I find another way to diffuse my co2. I have a aqueon hob filter for my 10 gallon tank. I use it diffuse my co2.

Moving a drop checker around various locations in your tank is the best way to tell.

The Aqueon HOB which came with my 29g wasn't big enough to diffuse the CO2 throughout the tank. Even moving up to a 250 GPH hasn't completely solved the problem. Setup is an Atomic diffuser placed just above the substrate directly underneath the HOB outflow.

If you have nothing else it's better than nothing. I have been using mine for years, but it's on a 55 rated for 175.
