Looking for information on water testing methods preferred by most and information on Natural Chemistry's Pool Foundation the pool store was trying to sell me claiming I will spend less on all my chemicals. I have issues testing my water. We bought our house 3 years ago and the 1st year I used a test kit with the drops for bromine, pH and alkalinity. I liked that, but sometimes had difficulty decided what the water color matched on the readings. Then the following year the pool store sold me test strips. I hated them. They were worse to get a true color reading on the strip to match the colors on the bottle. Then last year they sold me the accucheck machine. Thought it would solve all my guess work. Well I can test the same sample of water and get a swing in the pH of a whole point! So now I drive myself crazy doing all 3 tests and still guessing. I take a sample to the pool store once in awhile to verify.

Took water to LiteHouse pools yesterday and they were trying to sell me Natural Chemistry's Pool Foundation and was wondering if anyone had experience with this. They were claiming how great their pools were and using less chemicals.

I have a 25,000 gallon inground pool with DE filter, bromine and gas heater.
