I am first time pooler owner, 18k gallon chlorine pool. Purchase a home last summer with a pool, was not happy with the maintenance people that we had maintaining the pool. Tried a new company to open for us this year and we did not like them either, they treated us as if we could not ask questions to understand pool care; so needless to say we got rid of them also, so we are going to give a go and maintain it ourselves. I have seen a lot of references regarding this group, hoping to learn a lot. Thank you.
