First, thanks for all the help late last summer with my pool problems. With a TF-100 testing kit, some reading (ok, a TON of reading), using the BBB Method, and help from several members here, I was able to overcome an algae problem and learn the "method of madness" to pool chemistry.
Now with that said, our pool was installed May 2007 and this year will be our fifth season. Would like to know the recommendation for changing out the sand in my Hayward Pro filter?? I've read the manual and it doesn't say.
I know my grandfather, God bless his soul, NEVER changed the sand, and ran a pool filter for close to 20 years or more before getting a new pump and filter system. But I don't want to go the way of the "old school" process. (Sorry Gramps!)
