Kendall, did you buy this pump? I think these pumps may be for pond/freshwater use, it doesn't say anything about saltwater safe hardware or seals. I don't think there is alot of difference between their pond and saltwater safe pumps. I would find out before I purchased though.
This is from customaquatic's website about the details of sequence pumps:Buna seal with stainless steel hardware and PVC shaft SALT WATER SEALS AND HARDWARE.
Let me know what you find out about these pumps on ebay.
The pump does need to have the seals changed. He does not sell or provide them. It is definately a good deal but I am not interested in taking it apart to make it saltwater safe. I have not yet decided on what pump I am going to buy. I am still investigating.
