You should check to see what the pH is at the house. A lab test is not done on-site and the pH goes up in the time taken to transport the sample to the lab + how long it takes before it is tested. Check with a local water treatment company for information on water in your area> the hardness is low< your alkalinity will probably be low, and the ph is likely low. Have the lab do a Langlier Index on your water with the sample taken and transported in an approved container with no air and tested immediately on receipt. If they are not local, try a swim pool or spa dealer in the area.
