could anyone tell me have you or do use an aqua pro 3 external??
this filter is for a tank of 250/500 litres
there is also a aqua pro 4 400/700 litres
ive decided to get an external filter but as ive never used one before
wondered if anyone has one of these ?
my tank is 5ft it holds 260 litres or 58 gallons
wasnt sure which would be best
aqua pro 3
aqua pro 4
thought the aqua pro 4 might be to powerful??
if anyone could shed some light here much appreciated
