Hi i'm new to the site I have a 40gal tank and will be changing over to a 30gal. I have a aquaclear 110 right now. I was wondering if this was too stong water flow even on bypass setting. I was wondering if I go with a Rena filstar Xp2 and run a co2 reactor like dr fosters sells and run it from the output back to the tank? I am going to a 30gal cause no one seems to sell a40gal 36*15*16 like I have now.It used to be a saltwater set up but I wanted to try a planted tank,I've been doing saltwater for over 15years Any help would be greatly appricated!
