Need Help With My Remora Pro Please

[Mister_Palmer]

The last 2-3 weeks my PS really hasn't been doing a lot.
The foaminess is almost non-existent, and not a single drop in the collection cup.
The foam/water isn't even going up the collection cup shoot.

So, today I unplugged it, rinsed everything out, cleaned the pump slits (Maxi-Jet 1200), etc.

BUT, the thing that I think is causing the issue is beneath this little plastic screw. The pump is connected, and then this tube right here goes up and is stopped by the plastic screw.

Problem is, I can't get the plastic screw cap off. All it does is break apart and fall apart, so now it's stripped. But I think I need to get down there and use the brush and clean that area out.

Any suggestions on how to get it off, and if I do, will I be able to find a replacement to cap it back up? It really seems like a bad design to make it out of plastic IMO

It's the only area that I didn't address, so I can't think of what else could be making it not skim.

Here's the screw and the action that the PS is producing.

The Screw In Question:

thats the intake screw. never liked those skimmers. They work for a while then they don't.

It probably has carbonate build up on the needle underneath blocking the flow resulting in your lack of bubble production. I'd say get some needlenose pliers and try and pinch an edge then lift while unscrewing. It will need to be replaced if it's stripped. It may not be stripped though because from what I remember, if you srew them in too deep they will fall below the threads on the 90 and are hard to get back out. NEEDLE NOSE PLIERS!

Then call Aqua C (remora) to see if there is a replacement screw

Better yet, buy an Aquamaxx HOB or octo BH100

These skimmers use spray injection nozzles, with a special nozzle shape that disperses the spray some. Underneath that screw is the nozzle, and yes that's where you need to get in order to clean. Or, just take the skimmer out of your sump and soak the whole thing in vinegar water for a few hours (making sure that part in particular is submerged) then rinse it good.

These are okay skimmers - not prone to causing floods, but they do have to be cleaned periodically (best is with vinegar).
