Eric and Jarred talk about different types of pool covers. When it comes to winter safety covers, each type needs different chemistry considerations like dilution and CO2 off-gassing.
00:00 - Intro
02:35 - Jarred is wearing a Slytherin shirt. He's more of a Ravenclaw, TBH.
04:12 - Type of pool cover impacts your winterization chemistry (dilution, pH rise)
06:51 - Other types of pool covers that are not for winterizing: thermal and solar blankets. They are not safety covers and are not appropriate for winterization.
08:40 - Safety covers are designed to support a lot of weight to keep animals and people (and cars) out of pools.
10:54 - Mesh covers allow transfer of water and gas through it. This means dilution, and pH rise.
16:21 - Don't be afraid of high levels of calcium going into the winter (500+ ppm)
17:31 - Solid covers don't allow dilution and CO2 off-gassing
17:50 - Automatic covers can complicate things if your pool is heated a few times during the winter to swim, because the LSI goes from one extreme to the other. Surfaces can get destroyed because the water cannot correct itself.
22:08 - Solid safety covered pools do not need quite as much calcium as a mesh cover (400+ ppm), because it won't get diluted.
25:14 - Adjust chemicals at least a day before putting a solid cover on. Let the pH naturally rise up before covering the pool. If not, you need more alkalinity.
26:19 - Thanks for listening!
