HI! I have a Hagen CO2 unit in my tank and need to do a water change. What do I do with it during the water change? I need to make a 50% change and then an 80% change in another day or so. (I am doing water changes because my tank is cycled, wooo hoooo, finally and I need to get rid of the high nitrates)

I couldn't find any information in the instructions that came with it on what to do during a water change. I didn't know if it was okay to just leave the diffuser hanging on the side and just change water like normal or if I needed to take it out or????

Thanks for any help!
