I read somthing that said using a relay can be bad for a pump because they are designed to allways be run, and by turning it on and off you can dammage it. Is this at all true? I think a relay would be cool, but if it is beter for my pump, i would just run it 24/7. I am getting an Ehiem 1250, if it matters which pump is used.
Thanx,
