Be careful about an acid wash. Causes damage to a plaster pool (can you fill out your signature?). Only do it as a last resort.
I assume your area has very hard water?
The next step is to get the equipment all sorted out. You really can't do much to clear this until your pump and filter working. Can you remind us what is what with your equipment? I remember something about a tree falling on it.
Went to settlement last Thursday so the house is ours. There is a huge tree that fell right by the pool equipment that missed all the important stuff and only took out the PVC plumbing. Who knows if anything works but somehow the pool will be up and running for summer unless there are major issues. Seems to be holding water so hopefully no terrible cracks.
