kinda wondering the same thing. looks exactly like the pic in the book I have and it is labeled as immature so I am just going by that info. have not seen another since it was here 2 days ago. Found this pic online showing the first winter of the youngster. This is what I saw. Probably would be getting more color this summer would be my guess.
If you have a sump that constantly cycles I'd go with a setup like Awarrior. I'd also have 2 deep cycle batteries to lessen the chance of needing the water driven pump. Because of the frequency of startups I can see the pump failing as well. That would probably have me changing out the pump as routine maintenance.
