Go check out my 28g thread for phone numbers you can contact. Make sure you ask for the silicone grease you need to change out the seal, they don't send it, and its a huge pain to try and find locally if you don't have certain contacts.

After reading this thread this morning I decided to e-mail them regarding my pump as it has salt creep around the shaft as well.

Someone has already contacted me for my mailing address, great service! (so far, LOL)

It is an easy swap for the seals.

Reeflo says use a Gasgacinch product which I don't have, so posted on RC what to use. Seemed lots just use silicone on the seal and housing don't put anything on the seal face).

Yes...just dismantle the pump as completely as I could and clean it out. Aside from being a bit grungy, there were quite a few small snail shells stuck in the impeller vanes.

But as I mentioned, I could not get the impeller off in order to access the seals...even though I knew one of them needs replacing.

The impeller on mine was way more than hand tight. Just used water pump pliers (protected the impeller with a couple of wraps of electrical tape from the pliers teeth) and a screw driver on the end of the motor shaft.
