To be honest, that's where this idea came from. We was doing the same thing. The problem was that it took forever to get every last bit of detritus sucked up with such a small outlet. Solved that issue with the MJV :)
Yeah - it is kinda cool having it spread out like a vacuum attachment. I may order one to try it out and compare. Still doesn’t solve the problem of the MJ impeller getting clogged, but short of getting a larger pump I don’t know of a solution for that.

The MJV will fit the end of any MJ Pump (Marineland or Cobalt), as well as any hose with an outer diameter of 3/4in
The main problem with this setup is that it needs to be totally primed ahead of time. I just leave a 3” section of tubing on mine all the time and while it works fine, it definitely has a bit more trouble priming/restarting if there’s any air.

I just got mine a few days ago and used it in my sump. Worked like a charm. I had a lot of Marine pure dust/crap and it’s nice and clean now.

I'm so glad y'all posted in this thread today! I'd seen the tube clips on their website a while back after looking at the vacuum attachment and have been driving myself crazy trying to find where I'd seen them!!!

I have a couple MJ1200's laying around, this will be useful!
I think just about ever reefer has at least one or two MJs or other equivalent utility pump in their stash of old parts. Now we can make use of it - LOL
