Our pool is still under construction, but I have been using bleach to chlorinate since the project has been dragging out. Is there any downside to using bleach with a fiberglass pool? Will it affect the gelcoat? What about the seals in the pump? I just want to make sure that I am not going to void any warranties. We have a SWCG, but it is not turned on yet....won't be until the stone coping is installed and the project completed. Thanks.
