Swimming pools blog

A couple of questions (in-ground, gunite pool with Pebble-Sheen):
1) We have a floating chlorine dispensor that uses 3″ tablets. What
do we do with the float (or chlorine) while the solar blanket is in
place?
2) We have a attached raised spa with the pool. When the filter runs,
the spa overflows (waterfall) into the pool, which it should. But,
what do we about the solar blanket? Do we let it spill onto the
blanket, or cut a whole big enough so that the water won’t go onto the
top of the solar blanket?
