hmm..in a gyre tank, would a single koralia 1 be able to push enough water in a 3ft 40g?
Normally the auto answer would be no, but this is a low resistance case so no idea

I doubt it. Id go with the k4, but they are big.

well, my 40g was empty and I needed to clean it, so I filled it up and put in one koralia1. 1 didn't quite cut it, but i think 2 would. There were parts where water flow was fast, but just because of simple fluid dynamics, there were enough "dead" spots where 2 would really help elongate the water "slab"
