Tunze 6065 running in reverse

[downbeach]

Hello Roger,

I have two 6065's that we corrected this problem once before. I had the black propellers that broke the tips off and you replaced them with the new "blue" propellers, and they have been working good for the past 8 months. The new "blue" propellers have also lost the ends and are no longer able to start normally. I have them connected to a digital timer that alternates them for four hour periods, so they are turned off and on every four hours and once again at feeding time. Is the about the life expectancy of these units?

Thank you.

No, they should last much longer. Are you using the protective grids, 6080.200? Is there any chance a snail or hermit crab could be entering the pump?

Yes I have been using the protective grids since I installed the units, so no problem with any of my cuc getting in the pump.

I don't have an answer, it is odd though, that will be the first blue props I have heard of going out. I can send a couple spares, I just need your address.

I received the new prop's today, and the units are working great. Thanks again for your timely response and great service.
