How do you remove calcium build up on the bottom of an inground vinyl liner pool?
It is really hard to get calcium deposits off the vinyl liner my best sugguestion would be to get a brush to attach to your telascopic vac pole scrub the bottom of your pool as best you can , and then simply hook up your vaccum and go over it very well. I am in the pool bussiness and have been for a very long time and this is an effective way to remove the calcium from your liner. Another thing you may want to check is the calcium hardness level in your water if it is to high it could cause calcium build up.
