I am going to be getting a 90 gal set up. The tank has been running for a few years. It probably contains about 150 lbs lr and cc as the substrate. It also has a wet/dry filter with the bio balls. I did not plan to take much water (just enough to cover lr, cc & bio balls). I don't know if i am going to keep the cc or go to a sand bed (not a dsb since i am not sold on them yet). Also, from reading different post I am not sure if i am going to use the bio balls. Anyway, when i set this tank back up here, what type of cycle should i expect since the cc/lr/bio balls have bacteria? Should i set it up as is and then remove the balls and slowly change the substrate, or should i set it up like i want it and go from there?
