hydor coralia upgrade mod, flow blows you away
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 !!
