Building a Recirculating Remora

[hahnmeister]

Ill post pics. BTW, the parts I use are not 'water-tight', but in my case its fine because a little drip isnt going to be a problem since the skimmer is internal.

Here, bottom of this page you can see what parts I use for the recirculating pump. The clear hose part where the air line goes in is 1" OD, 3/4" ID. Then inside of that hose, I cut up a piece of 3/4" OD, 3/8" ID hose and slide it inside. The intake on the MJ, and the plastic conduit barb hold this piece in place on either side. Then I drilled a hole through both and ran the air line through (cutting the air line at an angle that faces the MJ intake to restrict the water even more as well to form the nice venturi). The intake of the MJ is held by the hose, and the output is held in the 1/2" plastic conduit by teflon tape. I suppose it wouldnt be that hard to seal up if one wanted to...

hahnmeister,
In your photo it looks like 1/4" OD tubing. Basically you did this?

 

[hahnmeister]

oh, do you mean 'could I use the exact same setup as I have already?'... sure. You will have to find some way to fasten the MJ1200 intake with a 1/2" ID hose and the outlet as well... They are both slip fittings, no threads or barbs...but I have seen it done with hose and hose clamps. OR, you could just run the remora in a sump...

Oh, You mean like this. Attaching the maxijet to 1/2" thinwall pvc.
A shameless pic of my recirc calcium reactor.

Hey, thats pretty cool. Howdja do that?

Ahhh,
1/2" thinwall pvc, a 1/2" pvc coupler, & some boiling hot water, some pvc primer/glue. That's what fits the intake of the maxijet.

For the outlet, 1/2" cpvc pipe glued into a 1/2" pvc plug bored out to 5/8" ID. Then drill or heat the glued combo to accept a 1/2" drill/maxijet outlet.

pvc primer/glue works great on maxijet.

 

[hahnmeister]

so you glued the MJ to the PVC... its permanent then, right?

Only the impeller cover of the maxi jet is permanent. The pump body can be switched out. 400 & 600, 900 & 1200 use the same impeller covers. Gives a little flexibility.

If you were going to do this internally, like in a sump. You would not need to glue them. The connections are darn near snug enough to be leak free. But you know how salt tends to creep.
I have a kalk reactor that is in its own auto top off reservoir. It uses the same connections to the maxijet. The water tests at 0 ppm. So no kalk leaks from the connections into the reservoir.

Thats pretty cool. Usually I see external MJs with hose and clamps on the inlets and outlets...like on the PM and Geo kalk reactors.
