hydor coralia upgrade mod, flow blows you away

[KevinK]

ok so I did a mod on my coralia 4 (put a sureflow impeller in) the flow now is stouning.

what was a nice pump for some flow became a tornado and blows water, I think at least 4x as much

I have to re configure the lay oute of some pumps so it dous not blast hings away

if you want more flow, but dont want to spend $$$, put a new impeller in and it will blast !!
