    Sealing jets and so on isn't technically "underwater". You should be fine with any quality kitchen/bath or marine silicone. I usually use GE or 3M depending on what's on the shelf.

    You could also try aquarium adhesive.
    My pool is a 10,500 gallon (420 Sq Ft ) kidney shape. A hand made sheer decent waterfeature. STA-RITE HRPB30, Sand filter 30" 98 GPM,
    1 HP Maxi-Glas 2 pump, BBB Method, Taylor K-2005 test kit, 50 Watt 12V low-voltage pond light illuminates the pool at night for a nice soft glow.
    250 gallon stand-alone hot tub. Got it FREE!

    and what is the proper way to seal it? i got a plastic gasket that comes with the jets and i dont know which side to put the gasket on. does it on the inside of the tub or the back side of it?

    The gasket goes on the inboard side. Be careful not to tighten the fitting too much or the gasket will start to squeeze itself out.
