Why do you ask? was it because of a show you saw yesterday? LOL
Hey Just kiddin...:tongue: I'm just playin
A frag tank should be treated the same as any other tank!! If you want to have nice looking frags the water quality needs to be the same or similar to the display or mother tank! So whatever you did to keep the tank you will be fragging from you should do to the frag tank! That includes cycling, water changes, testing params, in the same manner you should have also some sort of biological filtration i.e. LR or sand... another option is plumbing it directly to you main tank that way you don't have to worry about keeping similar parameters in different setups!
