Too cold to swim

It is still not warm enough to swim yet, the weather is awfull this year, so erratic. We get a couple of days of decent weather at high 30's/ low 40's, then the temperature drops back down again to low to mid 20's. Therefore it is not warm enough to get the water temerature up with the solar - as there is no heat.
We have set the temperature to max 32 degrees( lol) and the system closes down at night when it is too cold, so all is working. We just need some more warm days.
We have also closed the solar valves a little as it sounded like niagra falls outside the front of the house, as the water rushed down the pipes from the roof.
Meanwhile, testing of pool water continues, with addition of pH plus and chlorine to balance the water.
