Thanks redswi and SparKy697!
It was a thought but I think I will go for something like a Pentair. PetSmart has a decent price on them IF
they have em in stock here. Hate to drive all the way over there to find out, but their staff will tell you they have Great White Sharks in stock if you ask for em over the phone.
I'm thinking the 1200 series will do. I know that manufacturers pad their head stats somewhat. It's rated at 250gph at 2 feet. I should get atleast 200 or better. I just hope it will be enough to diffuse 12 liters of DIY Co2
! The 2200 is a bit out of my budget at the time being.
