You should use something made for cleaning DE filter like sparkle brand filter magic so you don't damage any of the parts a little more money now can save you alot later.Good luck
No you only backwash your pool when your filter pressure on your filter is high 30psi and above on most pools. If you backwash your pool be sure to add two scoops of de to your skimmer. If the presure is still high the u need to clean the filter
There may be a part broken inside the filter allowing waste to bypass and circulate back into the pool. You should clean the filter then inspect for cracks, rips or other damage.
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
If your water is staying clean it just indicate that there is not much dirt getting into your pool.
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.
Clean it out and start again. Check and manual for the amount of DE in the filter. Too much is like throwing money literally down the drain. While your cleaning the grids check for tears.
Salt is not a filter, it is added to pool water to allow a chlorine generator to operate.
Backwashing is done to clean the filter media in sand and DE systems. Cartridge filter systems don't have a "backwash" provision. You just remove the cartridges and wash off the dirt and debris with a hose.
If you're trying to clear up a murky pool, then the only option you have is to filter, back-wash, and add more DE and filter, BW, add more DE, until the water is clear.Try to scoop out as much debris out of the water as you can, top and bottom, and keep the bottom drain clear.You may be able to do a partial drain and refill.
Check the grid and manifolds for holes or cracks.
How do you back flush a pool filter?
There is no reason to use muriatic acid to clean a DE filter. If you disassemble the filter and clean each grid thoroughly with a hose nozzle, they will be clean enough. In the case of heavy minerals in the pool water, or long periods of time since last clean, the white fabric may be somewhat discolored. Don't worry though. That's not a problem. But be sure and take the time to examine each grid for tears/breaks. Replace any damaged grids found. I'm always happy to answer pool-related questions. Contact me at anjeli-klean.com
