Lol, the more bioload to the tank = more cleaning to do = more bucks expenses at the LFS. They're bright heh?
Some good cleaning crew are shrimps and snails, but the big of the job (cleaning glass) is the aquarist job's. There's no magic here.
Pond snails were doing great job before I introduced assasin snails inadvertly. Hitchhicking eggs on new plants... So now I don't have anymore pond snails -.-
