burgermeister,
I appreciate your thoughtful input. I'll be interested to see how long the system will run on a daily basis. I'm going to go out on a limb here and suggest that 8-10 hours of aeration is 8-10 times better than no aeration at all. I think I'll get more than that however. Plus, I'm using nature's energy, which beats paying the electric company more than I already do.
As for the cost of the system, you're absolutey right. If I were to do it myself I'd save some money. The same could be said for changing the oil in your car or building a deck, etc.
However, people make a living by performing services for others. Sometimes it's wiser and more cost effective to let someone else do the work for you. In this instance, that's how I feel. I don't have the experience in this matter.
I don't want to rely on a stranger's plans that may or may not be functional. I don't have the time to fix costly mistakes that would surely occur.
Again, I do appreciate your input. I just see it differently.
