Hi everyone, this is my first post on an aquatic forums but I've been fishkeeping for the past 8 years. Hopefully someone here can help me. I have decided that I'd like to use an external Co2 reactor since I feel that my Red Sea cyclone reactor stinks and seems to expel the Co2 to the survace before dissolving it at my current bubble rate of 2 per second. I didn't want to place another unit inline after my UV sterilizer to further impede the function of my Fluval 304, so I was wondering, has anyone thought of tapping a hole into a UV sterilizer and directing Co2 through that in a counter-current flow, much like the AquaMedic Reactor 1000? I currently use a Current Gamma 25w, which is a long tube and may do a very good job at this, if I tapped a line into its PVC housing. What do you all think? I just ordered an Aquamedic through e-bay but trying to mate up Fluval 304 ribbed lines to the 1/2" barbs on the aqua medic will be a chore. I'm very interested as to feedback for my idea, or for someone's idea as to how I could mate my 3/4 inch hosing to the aqua medic. Could I drill out the current barbs and replace with new ones from Home Depot? Reducers seem like that will add a lot of connections. Thanks to anyone that can help.
