This year I decided to replace our 18 year old sand filter (came with the house when it was built in '97) with a Pentair DE one. I did so after a lot of online research and just the general notion that DE cleans better than sand.
I was wondering if anyone has also gone through this process and if there are any tips or issues I should be aware of. Please keep in mind that this is my 2nd year of pool ownership so I consider myself still a beginner.
When I had sand last year, I just backwashed it every 2-3 weeks and that's about it. I'm told for DE you have to clean the filter once a week (maybe 2 depending on usage).
