Welcome to the Forum!

That's a Hayward Pro-Grid DE filter (looks like a 4800, which would mean it takes 6 lbs of DE when fully clean and only 5 when you use the backwash function) (as you are new to using a DE filter, you might want to take the time to read the first stickie in the Pool Equipment & Operations section here


It would probably be worth a couple hundred dollars to have someone come out and open your pool and go over how to run the pool with you. I'd advise scheduling it so that you will be there and can see what they do and ask any questions you have.

This is not to say that we can't talk you through it but I feel that if you see what they do and ask your questions while they are there, you'll get a better understanding of what's going on and will be able to do it yourself in the coming years

Please feel free to ask of us any questions you have about your pool. (thank you ! for the pic, if you ever need to replace parts, I'll know the specific part # for you to replace )
