JakeH;3891677; said:Koralia are the best powerheads for adding useable current to your tank. If you want "surfing current" for your vamp, the Koralia is exactly what you want. High flow at low pressure gives him a big gentle current to swim against without overpowering him. The AC powerheads are great for all kinds of stuff, but the hi-pressure blast output may not really be what you're looking for...
The Koralia powerhead appears to just circulate water and not filter it though and I don't want to fill the tank with filters and fans.
Maybe I will be able to make or buy an attachment for it that makes more of a surfing type current.
