So purchased a house with an AG pool, but wasn't hooked up when moved in. Just spent the day hooking up the filter and pump and filling the pool(it was half full when I took the cover off and was rather clear). I purchased a Taylor k-2006 test kit and collected all my levels:
CYA <0 (I filled the tube up but was never able to get the black dot to disappear)
Now I have just started the filtration, netting the leaves off the top and started vacuuming the pool bottom. Just wanted to know what my next step should be? I haven't added anything to the pool except water, I know the CYA should be around 30-50.
