So the heat has taken off the last couple of weeks here in Texas and the water temp has shot from around 84º to over 91º. Recalling how last summer was and how the water ceased to be refreshing at severl points, I was wondering if there is any reason a PVC pipe framework with aluminum foil wrapped about it would not help prevent the temp from rising so much during the day (sections of chopped pool noodle slipped on the PVC would provide buoyancy). My main conern is whether or not there will be a reaction between the chlorinated water and the foil and ultimately winding up with metal in my water (I presume that would be considered bad since copper and other metals are treated as such).
Since I am not the sharpest tool in the shed, I would imagine that someone else has likely had a similar idea, but maybe not enough people live anywhere that it is hot enough to both doing anything beyond running the pump longer at night and or water works to cool everything. I was thinking something that would be easy to toss in the pool and almost just as easy to remove, but that would limit the amount of sunlight allowed into the pool during the day (think the solar rings they seel as a non-solid pool cover, but completely reflective).
