Woa, Dan's thinkin! We bemoan not having affordable prop pumps and they are more readily available to those in Singapore.

I have seen pics of the koi hotel a couple years ago. Do you have any PBnJ?

Prop pump can move alot of water and that may be your only chance to overcome the friction losses caused by a spay bar type device. -Dan

I'm thinking of using such a pump

Turbelle® stream 6200

The flow is near 20,000l per hours at zero head, and the current is not 'pointed', so I believed even if the fish swim infront of it, it will not be 'injured' by the 'pointed' current.
