Yes, anytime your pressure increases on your filter, it will cut back on the flow you feel at the return. But, if you have little to no flow, then your pressure is too high and you need to backwash.
You may be adding too much DE. You only want enough to raise the pressure by 1 or 2 psi. Backwash your filter and note the clean filter pressure. Then, add a very small amount of DE. You may not see an immediate rise in pressure. I usually don't. Wait a half hour and if you still don't see the 1-2 psi rise, add a little more.
Good luck with getting your pool cleared up. I wish we would have been able to help you more.![]()
