Ok, I was up early.
Noticed this thread had no replies. Throwing out some remarks FWIW.
Many similar rated pumps may work, but is it really pumping 660 gph?
The Mag-Drive 7 pumps 700 gph. That's a hefty pump
Little Giant PES-700 does 725 gph
The Eheim 1260 pumps 634 gph
An AquaEuroUSA Apex does 656 gph
The Hydor L40 pumps 740 gph
All these pumps are priced at over $60 whereas a new Jebo AP3500 is only $32. That's one reason why I question the flow rating. The other reason is technical. A 1/2" diameter line would not be what I would use to carry 660 gph. I'd probably use 3/4" piping for that kind of flow.
If I were going to use the Jebo and the part that was missing is the 1/2" diameter threaded(?) part that connects the pump to the vinyl tubing, I'd check at a hardware store for a suitable threaded-barbed fitting.
Couldn't let this go yet
I found a video clip showing a broken Jebo pump impeller where the plastic blade assembly was no longer attached inside the magnet bore. From what I saw, I wonder if it might be fixed with gel super glue or reef safe epoxy. A quick search didn't find any replacement impellers for this pump. That tells me it's a cheap pump that's built to be trashed when the impeller goes bad!
Hopefully someone with direct experience with this CAD Lights tank or pump will jump in.
Aloha,
Mark
