Review: Fits Hayward 36 sq Ft DE filters - cheaper than your local pool store! - My filter grids developed tears after 8 years of use and I needed to buy new grids. Leslie's wanted $447 for the exact same manufacturer and model number grids as these and were sold out for at least 14 days. I ordered these and they arrived in 3 days with prime and fit perfectly. The water showed immediate improvement for clarity after the initial 10# DE load. I then vacuumed up the excess filter media from my pool bottom and within 30minutes the pools was nearly crystal clear. Will respond back on durability after the summer season. I rated the ease of install solely on the fact these grids fit perfectly in the filter housing - putting the filter back together is always a little challenging...lol Definitely worth the money especially at 1/3 the price of your local pool store! Review: Working great... price seems to good to be true - Just installed these today in a Pentair FNS 36sqft filter. The old ones were 6 years old and one of the grids had developed a few tears that were allowing the DE to flow back into the pool. Last year I had disassembled the filter and cleaned the grids and didn't notice the hole. I never seemed to get the flow through the old grids that I was expecting. Well I discovered today the reason why was because the grids were caked with calcium deposits which restrict water flow. Anyway, these inexpensive grids are working great, actually too good as I had to reprogram my multi speed pump to prime at a lower speed because the flow was now so high that the fountains looked more like a volcano exploding. I might grab another set at this price and put them in the shed. I figure if they last 3 years they will still be 1/3rd the price of the Pentair grids yet last half as long... so they're a good deal. ## Features - ☑️Direct DE Grid Filter Replacement for: FS-2003, FC-9530.
