We just bought a house with a pool and did a water test and the FC and CYA were low (FC .5 and CYA 30). I added two chlorine tablets, one to each of the empty chlorinators, (I believe they had just run out). I also added one more tablet to one of the skimmer baskets per recommendation from local pool supply store. The sellers were having the pool maintained but I don't know exactly when they stopped servicing it before we closed on the home.
The pool does have some Algae along the steps (green and darker) and some on the tiles and in a crack along the pool sides. My question is: as long as we get the chemical levels to normal ranges, is the pool safe to swim in even if some algae is still present along steps/sides? If so, I plan on shocking the pool after our first swim. If not, I'll just plan on shocking it first and waiting before we swim. Lady at pool supply store said it should be fine within a few hours as long as the levels are normal when the water is retested, but I'd rather get some TFP opinions.
This is an old, in ground gunite that is original to the house (house was built in 1964). Eventually, we plan on fixing the cracks, replastering, adding a second drain, and redoing the tile, coping and decking which are all in need of some TLC, but our kids (7, 5, 2 and 9 months) are anxious to swim it, but I just want to make sure it's safe before doing so.
Thanks in advance,
