Green algae? Mustard algae?

Well you don't have the highest rates. Ours are about 0.35/kwh in Northern California if you hit over 300% of baseline. The baseline is set so low that you would have to live in a cave to meet it. It is not adjusted for large family or anything. I have energy star appliances. My new pump keeps me below the rate, but just barely so I ONLY pay 0.32/kwh!

Do you have an electric heater or a water well with a pump? Is that how you are saving on electricity? I have a gas heater (along with my solar heater) and municipal water so I can't see where a cover would save me anything but on my water bill. It would also allow us to swim much longer around here, but my pool is a large, odd shape so it would be cumbersome to use.

I have brownish algae spots every now and then in a dead area of my pool, but brushing allows the saltwater chlorinator to keep it at bay.

From what I have learned on this forum, it is safe to add bleach through the skimmer as long as you don't have a trichlor chlorine injector in use. The bleach makes a short trip through the filter and heater and is quickly followed and diluted by pool water. As long as the pump is running for a few hours after you add bleach, it shouldn't be a problem.
