hydor koralia pumps

[Charlie Davidson]

I have 3/4" acrylic tank.. will the magnets hold?

[Jeremy B.]

They will, but it's not going to be a strong "fit" really. I think I would personally look at doing something different.

I'd have to agree with that, i have 1/2" glass and they dont hold strong so 3/4" will be weak imo.

[Charlie Davidson]

Agreed! On waiting list for MJ's
I am also calling about skimmer parts needed ASAP!!!

The K4's I got (2 of them) would not reliably hold on my 1/2" glass tank. If you didnt really press hard and form a suction they would fall right down. Hydor sent me two new magnets and they we slightly better but I still feel your getting more holding power from the suction than the magnets.
