What Is The Best Position For A Filter To Be In?????

Question

Hi,

I have a RENA filtration system on a 30 litre tank and I was wondering where the best place for the filter would be, whether it is best at the top, middle or bottom of the tank and whether it makes any difference to the fish.

Thanks in advance for any assistance

Answer 1

you can try in the left hand top corner. then cover the filter with plants and other decor.

Answer 2

the link is not working,fix that.bottom is better

Answer 3

Top.  You want to circulate the surface of the water as much as possible to encourage oxygen to be absorbed.
