Mike-my pond is just under an acre. The brand of the Top Water Splasher is Kasco. From what i read here and from my sources once you buy one and run it 1/2 time it will last 15-20 years. I went and put a 230 Volt 2 horse in as it is cheaper to run 230. I don't think you can buy one(2 horse) at 110. Look under my post in Q and A on trout and the systems are explained well. If you buy a 2 horse that will be plenty for up to a 5 acre lake. If you do a search on the Internet you will find the suppliers. Let me know what you decide and how it is going. One other thing that i learned this year is i was losing a minimal amount of Trout this spring. I called my consultant and he asked if they were females and they were. They looked drawn up and stressed. What he said was once they hit 1 or 2 years the females will re absorb the eggs as they cannot spawn in a pond. During the second year some of them die when trying to spawn and this is natual. I lost three out of probbly 80 females. I am intrested if anyone knows the scientific reason for this occurance. Have a good summer.
