Need advice regarding new spa jets

[bizzle]

I currently have 10 jets in my in-ground spa. There are six along the wall and two at calf height and two at the feet pointing straight up.

They look like this:

Should I just clean these up and put them back or are there better ones that would pair with my 3HP VS pump?

Also, if my light is not working and the inside of the socket has evidence of corrosion/lime (with no water inside the fixture) then does that indicate the fixture is leaking from the back and needs to be replaced entirely?

You are kinda stuck with the nozzles that fit your jets although kinda weird you have two different nozzles. If you have a little electrical experience you can find where the light junctions and undo the power source from the light cord. Using a decent meter ck the ohm readings between line(black) and ground on the light cord and white and ground. You should have no resistance.

I was hoping I could get different size holes to change the flow or double ended threaded nipples to extend the threading and put some eyeballs on or something like that. The different lengths I have are due to where they are located: the size longer ones in the walls and the four shorter ones in the floor and seat. In any case, I need one of the long ones because it's missing. Do you have any idea where I'd find them?

I found these: Venturi Tees | Replacement Spa Hot Tub Parts | Yardandpool.com

They look different but similar. My current venturi tees have 7/16" holes. But now I only have one pump, a 3HP Intelliflo, with 10 jets I'm thinking I should go down to 1/4" holes?

Where would I buy these other than online? Also, where do I find the eyeballs or whatever go in the hole other than the venturi tees? I'd like something to direct the flow.
