Creating a tank with fast current

[Industrial]

I bought a 40br for my small vampire tetra who needs fast current. I bought an aquaclear 20-50 gallon powerhead and I am wondering if that will provide enough current. It is either that, or an aquaclear 110 powerhead but that could be too powerful.

Does anybody with powerhead experience know how much current powerheads create and which one would be better for a fish that loves current?

I use Koralia powerhead to create current. There is no scientific evidence if fish grow faster in constant current water but I believe it's probably beneficial to replicate the environment they came from.

Go to www.loaches.com and check out the info and articles on hillstream loaches and how to make a river tank manifold for one way flow with minimum backflow.

Cheers,

I would prefer that he grows as slowly as possible without any harm. I just know that he needs the fast water or else they won't live a long life.

What I am looking for is how much current does a powerhead make compared to a filter of the same size. Also, how much current does a powerhead rated twice as large create and can it be dangerous to a fish that likes current?

Right now a 20 gallon with a baby whale. The 30 gallon filter is not nearly enough for this guy. He is going to a 40br. 36x18x16 I believe.

get the aquaclear 110 you can always adjust how strong the current needs to be

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...
