so happi, what do you suggest for a sump or a high flow filter?? I wanna use one@work but the mist is killing me..i run the line into the return pump right now and I only get but so much diffusion. Thanks!
i don't know much about sump, but, i do know that it will take out lot of co2. with the high flow filter you must use 20" or higher housing and use a sponge inside it, this will help the co2 from escaping and you also get better diffusing this way.
