I back wash the filter ( DE starite ) and the pressure drops to 12 - 15. It stays like that for approximately 1-2 hrs., then it gose up to 30 - 35, and it stops sucking water into skimmer and push water out of jets. I back wash it and it dose the same thing over again, I am running out of D E.
Filter keeps loosing pressure

What does the water look like?
The behavior you describe is completely normal if you have algae, or are in the process of cleaning up dead algae.

Yes the pool was green, and I'm in the process of cleaning it, do I have to keep back washing the filter and adding DE to it.
Yes, and you should backwash when the filter pressure increases 25% above clean filter pressure.
What brand of filter are you using? What you're describing is a great testimonial to its efficiency!
If your filter has a rotary multiport valve, you might want to set it to recirculate if you leave the pump running and you won't be around to keep an eye on the pressure rise.
And when the pool is all clean and sparkling, you probably will want to do a full teardown and cleaning. Instructions.

I agree, if you can set to recirculate while you SLAM (see Pool School) you won't have to worry about the pressure rise. The dead algae should sink to the bottom then you can vacuum to waste... if you don't have a multiport valve, the process a bit more tricky....
