ok so what about which one, if I want to use it on my 30 GAL and i already have the Eclipse 3 filteration, and I want to upgrade to a 55 probably in like 5 months, do you think the XP2 wil lbe fine? that will come to about 70 shipped. But the XP3 is only gonna be about 10$ more with tax so that is smarter, will the water current be too much with an XP3?
