    Is there a sticky on chems??

    I'm starting up a new pool and am needing to do 2-3 different things to my water. I was wondering if there is somewhere on here that tells what chems you shouldn't add together. I pretty much know what I need to add, just didn't want anything to meet together in the water and not like each other

    Thanks

    I thought there was, but cannot seem to locate it.

    A safe bet would be to wait an hour with the pump running between each addition.

    Chemicals one might add to a pool:

    Chlorine
    Acid
    Baking Soda
    Borax

    Acid pretty much does not mix well with any of the other three in high concentrations so don't ever mix different chemicals in a bucket or other small volume. However, in a pool, chemicals dilute very quickly so there shouldn't be an issue adding chemicals one after another but if you really want to be safe, always add acid on the other side of the pool. But really, you should never need/want to add acid with Baking Soda or Borax (counter productive) so the only real issue is acid with chlorine.

    Thanks guys. What about calcium chloride??? My CH is very low. 80 and should be around 250 for FG pool, I think.

    To be completely safe it is best to add CH only on a day when you aren't adding anything else (except the routine chlorine dose).

    Thanks Jason. I believe FPMom told me the same thing
