I decided to try adding some DE to my sand filter to try and improve my clarity a bit more. I should have added it more gradually but I eyeballed it. After a few minutes I checked filter pressure and it was up just a bit more than 1psi (19psi->20.5) so I thought I was golden. I just checked 3 hours later and pressure is up about 4-5psi (24psi). Any risk in damaging my pump or filter system with that much pressure rise?
