I don't know if anyone's answered your pool temp/algae question or not, but just in case they haven't...
As long as you maintain the proper level of chlorine for your CYA level, you should be OK with higher pool temps. My pool routinely stays around 86 - 90 degrees in the summer, and I never have a problem. The chlorine (which is the sanitizing agent for your water, btw) will kill off any organics in your water (algae and bacteria).
I know at first it seems like a lot of work, what with draining the water, adding bleach, brushing the walls and floor, and all the testing you'll do, but after you and the Farmer get the water chemistry right, your pool will become rather easy to maintain. You'll learn your pool's tendencies and adjust your testing schedule as necessary. Keep the faith. :-D
