i think i still have my lifereef u-tube overflow. let me check this evening. i'll let you know.
i upgraded to his twin tube overflow, not exactly happy with that to tell the truth. one tube keeps slowing losing siphon (pita). i almost thought about going back to the single but my upgraded pump is too strong for a single (hence my problem above).
i think i still have the single though (if the wife didn't toss it "accidently") <_<
the good news is i do have the lifereef overflow unit. i cleaned it up and other than for some stubborn coralline still left in the corners it's fine.
now the bad news, i'm missing the little nylon wingnut & screw that connects the two chambers. i can't find the fuggin thing. also, i don't have the correct length u-tube. i had modified the original tube so it can work on my double-tube overflow (as a backup/alternate for cleaning).
so i have the setup but it's not 100% complete. i'm still looking for the screw though but the u-tube is no longer useable for this unit. let me know if you're still interested.
