Its a totally different rating... if that makes sense... like your mj will push a hard flow in a really restricted area, and it seems to die over a short distance accross the tank...
with the koralias, you can put your hand in front of it and not feel very much current, but you look across your 48" long tank and you see sand blowing all over the place...
its just totally different...
You gotta love markaneering!
OUR PUMPS ARE FAR SUPERIOR, BUT DON'T LET YOUR EYES BE THE JUDGE. WE SAY THEY MOVE WATER MUCH MORE THAN THEY REALLY DO AND YOU NEED TO BELIEVE US BECAUSE....WE PRINTED IT ON THE PACKAGE...AND WHY WOULD WE DO THAT UNLESS IT WAS DA TRUFF...ERM...THE TRUTH...EXCUSE ME.
