You add D.E. to a pool when you do a fresh filter clean. You also add D.E. if you have to backwash your pool more than normal. When you backwash the pool it is also dumping the D.E. out so it needs to be replaced to keep the grids covered so the pool can filter properly. Hope it helped

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.
How much de powder for 17000 gallon pool?
You add diatomaceous earth (de) powder to a pool based on the size of the filter. Most pool filters have a plate on the side telling you how much de powder you need to add. If your filter does not have such a plate, the general formula is that you add 1 lb. of de powder for every 10 sq. ft. of filter area. That is, you need to measure the length, width, of your filter, taking the pleats into account, and use the formula "sq. ft. = length x width" to determine the square footage of your filter.
Do you have to add DE powder everytime you clean your DE filters?
Yes. It is important because grids inside will not get clogged by dirt, dust and other elements getting into pool and will not brake that easily. Also pool water will look better and you will have easier filter cleaning next time. Add some D.E. after backwash, too.
Can you swim in a swimming pool if DE gets into the pool?

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.
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.
How do you clean an extremely murky pool with a DE Filter without constantly having to bump and drain the filter?
