That would depend on the filter . the best thing to do would be to contact the manufacturer of the filter.

When do you add DE to a pool?
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
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.

Intex pool with slime on the walls and floor?
I use the Intex pool startup kit. It has sanitizer, pool test strips and shock. Add Sanitize which is granular chlorine. If you have a pool brush, brush pool. I actually use a mop. If its really dirty you may have to get inside pool to mop, in which case add Sanitize after. Then run filter for 20 minutes and use test strip to check pH & alkilinity. If not right pH add another dose (booklet in kit says how much per 500 gals of water)and run filter another 20 min. Then add Shock and run filter 4-8hrs. If you don't have a filter, then you probably have to drain, clean with regular liquid bleach & mop then refill.
