Silicone is good, but may contain fungicides. Aquarium stuff is going to be fine, while cheap bathroom sealant isn't even silicone. Though might be a blend, unsuitable for constant immersion.

Shame we can't see it. These get a lot of use. Your local wholesaler will ask about 50p each, but be sure they are watertight ones, or you won't get the rubber washers

Use rubber grommets. You shouldn't need any sealants in a properly built system. I did use silicone on a manifold but that was just one time.
