Hydor Koralia Powerhead 240gph...Any Good??

Looking for some flow in my 20 gal long. Is this any good? Any benefits over a conventional powerhead?

Absolutely.

You're getting turbulent flow with a Koralia submersible propeller vs. laminar flow in a conventional powerhead. Propeller pumps tend to cost a little bit more, but are also more energy efficient.

I'm guessing that the 240gph koralia is the newer nano one...if so, i wouldnt use that in a 20. I'd go with at least a #1, possibly a 2. I've got a #1 that started off in a 10 and was perfect, and now its in a 16g bowfront and is still great. The nano one would just be too small for a 20g tank IMO, specially a long one. They really disperse the flow, so it wont seem strong at all, which is why i suggest getting the bigger one(s).

2 of the #1's in a 20g long would be great IMO. I'm a big fan of LOTS of flow

Yeah, I agree that the Koralia pumps are very nice, and I also agree that the 240 gph version is probably too small for your tank. the #2 might be a better choice, but it does depend on your rock structure quite a bit. I have a similiar pump, a Tunze 6045, rated at 1189 gph, in my 29 gallon Aquapod, and it's definitely not too much flow.
