what size powerhead should i get for my tank

[johnatbhs]

i was thinking of getting a koriala 3 or 4

the 3 is 850 gph

the 4 is 1200 gph

in a 55 short which would be better. (36x18x18in)

 

[special lighting]

3 would bee good but for 5 or 10 $ more you could get even more water turnover with the 4

it's a short tank, but you'd be better off IMO getting 2 pumps instead of just 1 large one
