Sump for 50g
 

what is the smallest size of tank you could use effectively for a 50g tank I'm limited in my space under my stand

Your old 20.

:mrgreen:


.

Thats what i was thinking Alan but with my space under the tank. The 20 doesn't leave alot of room for a pump unless i go with a submersible

whats wrong with a submersible?

thry tend to add heat to the aquarium
