Hi. 5000 gallon above ground pool set up with Baquacil out of the box last summer. Want to switch to chlorine.
Completely drained pool for winter. It completely filled with rainwater this winter, and I drained it and it sat dry for a few weeks. Some silt, leaves and pink growth on liner.
Filled it about 5 inches deep and added some bleach and scrubbed the liner. Drained. Rinsed. Drained. Liner is sparkly clean.
Filling with water as I type.
Do I need to change the sand in my sand filter? (Actually that crushed recycled glass medium). Or can I just backwash it really well?
Anything else I might need to be aware of if I just set the pool up with chlorine this summer?
