Location of CO2 diffuser

I have a dilema. I have my CO2 diffuser on the left side of my tank. There is a lot of hairgass in my tank fyi. The hairgrass on the left is covered the entire left side while on the right side, the hairgass has only covered little of the substrate. Should I move the diffuser around?

Not sure if I understand. Are you afraid the hairgrass is going to grown onto the diffuser?

I think that you are wondering why the hairgrass is denser closer to the diffuser? I have no idea, but I wonder how much circulation you have in your tank, possibly you are not moving the nutrients around enough?

I've always placed my diffusers in the middle area and had no adverse problems ith more growth on one side. At least not that I noticed. Is the Co2 being diffused through some kind of pump or powerhead?

Agree. What kind of filter do you have in the tank. Maybe you could position the diffuser so that the filter outlet blows across it, thus distributing the CO2 enriched water around the tank better.

I currently use a glass diffuser and a Rena Filstar XP1. I wanted to position the spray bar on the side of the tank but my 20 gallon was no long enough so I put it towards the left-middle. Is it possible to saw the spray bar down in size so I can fit in on the side of the tank?

I would think you can shorten your spray bar, but if you do you'll probably need to make the existing holes bigger and add a few new ones too.

I cut the spray bar on my filter with no problems. Didn't add more holes and I didn't make the existing holes larger.
