Start by cleaning the entire filter. Disassemble and hose off the grids. Without this process you are just guessing as to what is already in the filter. Reassemble. The formula is usually on all DE bags . . . you have to know the square footage of the filter. This is usually stated on the name plate of the filter. Such as 36 sq.ft; 48 sq.ft.; With Hayward it is usually 4800;3600 etc. An easy to remember formula would be take the sq. ft, divide by 5, this answer will tell you how many cans or scoops of DE are dumped into the skimmer. Example: 48 div. by 5 = 10 rounded off. Note: if your filter is more than 1 yr old ~ your filter will have a residual of old DE left in the tank after each Back Wash ~ it never totally removes all the old DE and dirt during a B/W ~ this accumulates so that is why you clean out the filter tank. This formula will give you an even and uniform coating on all grids ~ the DE is what is doing the filtering not the cloth grids.

How do you get DE powder out of the pool water?
Firstly you find out how the DE got into the pool - must be a broken filter pad. Fix that, then vacuum the pool. No point vacuuming before you fix the filter problem, or the DE will finsih up back in the pool.
Is Salt filter better than DE filter for pool?
Salt is not a filter, it is added to pool water to allow a chlorine generator to operate.
Why would a DE pool filter pump the DE back into the pool via the water jets as soon as DE is put into the skimmers instead of adhering to the filter?
Check the grid and manifolds for holes or cracks.

How does a DE filter work on a pool?
Simply put, Diatomaceous Earth (DE) are the bones of tiny little animals that lived millions and millions of years ago, diatoms. This DE is used to coat the "grids" inside the DE filter which captures and filters particles as small as 5 microns. When the filter pressure rises, the swimming pool DE filter is backwashed in the same manner as a sand filter. A slurry of DE is put into the skimmer to "recharge" or "re-coat" the grids of these swimming pool DE filters. This type of filter is effective and efficient but a little more expensive to maintain. Some call it the "water polisher" of pool filters.
Can a pool with a salt generator be used in conjunction with a DE filter?
Yes

How much de do you need for a 18x36 inground pool filter?
The amount of DE (diatomaceous earth) needed for an 18x36 inground pool filter typically ranges from 1 to 2 pounds per square foot of the filter's surface area. To determine the exact amount, check the filter's specifications, as they often indicate the recommended DE amount. Generally, an 18x36 pool may require about 4 to 6 pounds of DE, depending on the filter model. Always consult your filter's manual for precise guidelines.
After backwashing a pool do you need to add earth back to the filter immediately?
Yes, after backwashing a pool filter you should add diatomaceous earth (DE) back to the filter immediately if you have a DE filter. If you have a sand or cartridge filter, there is no need to add anything after backwashing.
If your DE filter is bad and there is DE entering the pool can you use it without DE until the new filter you ordered arrives?
To be honest you're best off just dosing the pool will a few litres of chlorine and letting it sit. The chlorine will prevent it from going green. Without DE powder it won't filter properly and you'll find you have pressure issues with the pump and filter.

Why is my pool cloudy?
Any particles in your pool can cause cloudiness - for example, dead algae. To eliminate it, most pool stores sell a "clarifier" - the one I sell is blue - which will get the particles out of your pool, or "alum" or "floc", which will bind the particles together, making them heavier, dropping them down to the bottom of your pool. You can then vacuum them out with your filter set to waste. If you have a DE filter, and you add a white powder to your skimmer sometimes, it is possible that your filter is leaking DE back into your pool and you need to replace the grids inside it.
