Hi, I am new to the forum so I am always searching for good information. Last year, we moved into a house with an in-ground pool having come from a house where we installed an above-ground. This summer will be the second season using all of the new equipment I installed last year but I will be continuing to make modifications this year. I replaced the pump, all the plumbing and the filtration system shortly after we opened the pool last summer. While everything is working well, the chemistry is quite a bit more finicky than I am interested in keeping up with. More to come....
