I have a 13K gallon inground pool that is maintained with bleech, borax, baking soda, etc. thanks to this website and is doing great. Next summer, we are planning on going away in the RV for two to three weeks. Any suggestions for pool maintenance while we are gone? Can I just get the chemicals right, shock it good and put the cover on it with the pump circulating and go or do I need to have someone check and add chemicals daily while we are gone.
