Description
Pentair 59003000 Full-Size DE Filter Grid (Single), 30 in for FNS Plus 60 and Nautilus Plus 60
One full-size grid element, not a complete set.
Genuine Pentair 59003000 full-size DE filter grid element. This listing is for one (1) full-size grid only, not the complete 7-large-plus-1-partial set. Use it to replace a single torn or collapsed grid in any 60 sq ft Pentair / Pac Fab FNS, FNS Plus, Nautilus, or Nautilus Plus DE filter. If you need every grid in the tank, you want the full 59023300 grid assembly instead.

| Per Full Filter | 7 full-size grids (this part) plus 1 partial grid |
How many of these does my filter use?
A 60 sq ft FNS Plus or Nautilus Plus uses 7 of these full-size grids plus 1 partial grid. Each full grid contributes about 7.5 sq ft of filtration area. If you are doing a full grid pack replacement, order 7 of this part plus 1 of the partial grid (Pentair 59002900).
How do I know if my grids need replacing?
Pull the grid pack and inspect under good light. Replace any grid with a visible tear, hole, or collapsed plastic spine, or one that is discolored brown all the way through (sign of long-term oil saturation). DE pushing into the pool, short filter cycles, and high pressure right after a backwash are the field symptoms of a torn grid.
Can I use just one new grid alongside seven old ones?
Yes, single-grid replacement is the most common service repair. Just make sure the manifold tabs seat the new grid evenly and that the top air-bleed assembly compresses all grids uniformly. Mismatched compression is the #1 reason a new grid tears within a season.
