Good morning! I need some guidance with my pool. It was filled yesterday, 20000 gallons by a water hauler and the rest from my garden hose. The pool is 21x 43 AG oval. Supposed to hold 28,000 ? Anyway it is filled, pump is running and I can't seem to download the info I need to get started. It is using a cartridge filter, and supposed to have a copper secondary filter which isn't installed yet. I only have test strips at this time and they are telling me that the PH is 6.8, free chlorine is .05 alkalinity is 40 and culturing acid is30-50. Where do I start with this? Any help will be greatly appreciated.- Melinda
