Thanks for the info, i don't have an overflow box and i am kinda worried about the problems with loosing power and such causing a big mess in the floor. I did go to the LFS today and i found a filstar xp3 for $113 they also had the xp4 but had none on the shelf for $120. The xp3 had 175 U.S. gal : 350 U.S. gal/hr the xp4 had 265 U.S. gal : 450 U.S. gal/hr would either of those be a choice to look at? After thinking about it i figured it would cut down on problems if i bought a canister filter. Or spend the extra for a fx5 but would rather not do that just yet
