Read the manufacturer's manual on the filter. They give specific amounts of sand for each size of their sand filter configurations. I am not aware of any set formula in general. k
My Ranger manual states 18" requires 200 lbs of media.
Your filter will tell you on the side of it how much media sand to put in it.
Nothing if its a sand filter However if sand is coming into the pool from the filter then you may have to replace one ore more laterals in the sand filter as they have worn and are letting sand through to the pool,
140# of sand is required.
If you have a sand filter the laterals in it may be starting to show signs of wear these wil blow sand from the sand filter into the pool when they wear out.
For what? Building a cove for a vinyl liner. Adding sand to a sand filter. Building a sand box. For the base of a pool. ????
It could damage the internal PVC of the filter and cause sand to get in your pool.
The sand filter wont make a pool green this happens a s a result of algae.
If you are getting sand coming into the pool and have a sand filter you may have to replace worn laterals in the sand filter.
No.
Yes, it just depends on what kind of sand it is
One of the lateral returns inside of your sand filter may have snapped. When that happens, it can send sand out of your returns. Have your local pool place repair your sand filter.
You might have too much sand in the filter. I use a diatomaceous earth. When I used too much there was leakage back through the strainer.also I found my pipe cracked inside my filter bowl and sand was seeping into the pool, removed all sand and did some home pluming replacement.very simple job to do...
