Solution for hanging Vortech MP-40s

[raylinds]

I have been struggling to mount my Vortech MP-40 dry side motors to my tank to keep them from falling off. I have use 3M stick on zip ties around the cord stuck to the top of the rim, but they always lose adhesion and fall off within a day or two no matter how well I clean the rim before sticking them.

Has anybody found a better solution?

Thanks,
Ray

No, I haven't. I just replaced a dry side that bounced on the floor and went noisy.

I have 2 mp40 and 2 mp10 (separate tanks) and the only time they fall off is if I hit them. I'm not using anything but the magnets. I use the included cord mounts and have had to use a knife to pry them off when I have wanted remove them. Are you using the correct spacer? How thick is your glass?

I wasn't very clear. The dry side is not just randomly falling, only if it gets bumped, but I would feel better if they were securely mounted to the aquarium. Maybe it is the material my rim, but the adhesive won't stick. Even the lightweight ATO tube comes unstuck after a few days.

They are asking what size tank you have and what spacer you are using to keep them connected. Maybe the easy solution is to use the 1/2" spacer which is just a sticky pad and see if that resolves issue. Especially if glass is 3/4" thick

This might help. You can probably make a 3d printed one as well.

Try to the glass it will stick much better

I answered that the problem is not the dry side falling off randomly so the question is moot. I have the proper spacer. My question was about attaching the cord.

Thanks- that should do it.

If a longspine urchin sticks his spines into a Vortech and stalls the wet side the dry side will jump off the tank. The same if a snail crawls inside and gets jammed. I have watched it happen.

The tabs that came with my pumps failed when the black plastic piece you put the cable tie into pulled off the double sided foam still stuck to the rim.

A little j shaped hook that slipped over the rim and faced out to put the cord into would be ideal

Yeah it does happen, it's a loud thud of regret. mp40s are great NO WIRES IN THE TANK yay!!! But you gotta have the dry side ziptied to the glass with commercial style sticky backs or else lol

Sounds like you have all the answers to your questions so it mute. Hope it works out for you.
