    Any damage from early chlorine upon replaster start up?

    We are ready to add chlorine to the pool this evening so went to fill the automatic chlorinator.... found it has trichlor tabs in it! I didn't load it, husband didn't load it, it had to be the plastering crew. So, given what was in it, perhaps 3 pucks could have been in and been dissolved, max.

    Is there any possible damage that could have been done to the pool with this?

    3 pucks in 3 days will have added almost nothing to the pool, 4 ppm CYA, 6.3 ppm FC which would be gone in sunlight pretty quick, 5 ppm salt.

    The National Plasterers Council recommends no chlorine or CYA for the first two days. After that you should ramp up slowly. However, the effects of ignoring this advice are normally quite small and rarely noticed at all.
