Aquarium Advice Addict
So I've decided to surrender and do a DIY Co2 system with a forced reactor. I read the article by John LeVasseur which illustrates a nice DIY system, but I need to know about the PH and the Gravel tube - His design is for a 55 gal and a 10" tube - I have a 20 g H with 16" total height -so, I obviously need a less powerful PH and smaller tube - any ideas?
