hello. I tried researching my specific question but to no avail. I've been using the site to get my pool in good shape, and have had great success. I try to do things as economically tight as possible. We'll be heading up to the San Jose area for a year, and I'm trying to add 6% chlorine automatically. I've come up with a simple outdoor 120V timer, and a small submersible fountain pump, (~1gal/min). I know heat and sun and time degrades chlorine. I'm thinking of putting the storage container inside a larger container and packing with dirt/soil in the space between the two containers, and periodically wetting the soil. i want to put this setup in a shaded area all in an attempt to keep the chlorine as cool as possible outdoors. I'd like to be able to go 30 days between refills at ~ 1/2 gal every other day. (7.5 gal/month) so my questions are: does sun degrade chlorine more than heat? will making the container opaque and standalone do just as fine? does diluting the chlorine with tap water make it last longer? will 6% chlorine damage the sub pump? (metal 4" cylindrical outdoor fountain pump).
thanks for any and all detailed input. And lay it all on me. I was an engineer in a past life. I can hack it, lol.
