NEED HELP - Grow Out Tank = Confused
im getting a fluval 120 ltr tank, basicly for free, but its only the tank. so i need filtration.
im confused what kind of filtration i would need for this size tank. my current 25ltr tank has arround 100 jewel cichlids, 10 yellow labs and 30 peacocks. all still very small.
any tips would be much appricated
was thinking sponge filter(S)? would they do a tank of this size? many thanks
