I found this forum last year. I've got a lot of help just from lurking and reading the Pool School articles.
Some things I've done based on the information here: Started using TFTestkit, deep cleaned the sand filter, replaced the motor on my pump, converted to SWG pool. Thanks for all the help so far.
Dealing with a green swamp since we opened the pool (9 days ago). Hoping to get clear water soon.
