If I wanted an internal wave pump I know there are a lot of good options out there. I buy the Vortech's because of the small footprint and the motor housing being on the outside of the tank. To my knowledge their arent any other pumps on the market that offer this advantage. Until someone offers a solution that is a direct competitor to Vortechs I guess I will be checking my wetsides as part of my normal maintenance routing.Sounds like you all should look at Tunze as a solution for your problems....just saying I have pumps that are 15 years old and not cracked or rusted. Do you want a Porsche or a Yugo...your choice.
