I think that is the way to go. I went out this evening and pulled the cover back just enough on the deep end and with the light on I could see the bottom. Lots of crud down there like usual in the spring but the water is pretty clear. The warm top layer only goes down about a foot or so and then the water is still cold. I did put a chlorine floater under there with some tabs but tried not to disturb it too much. I also put some more water on the winter cover so the surface water under the cover will stay cooler for a few more days. We are back in the 80's for a few more days so that should help too. Luckily June wasn't really hot, we had lots of rain and cool temps.
