You don't need a powerhead, but I use them and like them. In one tank I use it to move poo off the surface of the sand and into the filter's intake.

On my planted tank I use one to disturb the surface of the water.

 

thanks

 

wat powerhead would you suggest for a open 60 gallon

 

I use the ones from walmart, they are only like 21.00 and I have had mine for 7 months and they are going strong.

 

1 2 3 how many

 

I run two of them with 6" sponge filters at their base. I put them in the back corners and point them towards the front middle of the tank. You can hide them fairly well with plants or rocks.

 

nice ty but wat are sponge filters
