Fiberglass hot tub — chlorine tabs? Shock

[Hyrul]

Hi all,

I live out in Medellin Colombia and have had a jacuzzi for a year. The jacuzzi is made out of fiberglass.

The manufacturer (who also does the maintenance) has always suggested I use chlorine tabs and a liquid PH raiser when needed.

I’ve noticed that the fiberglass shell has taken a beating and looks scuffed on certain locations.

I went to a local pool supply store and they said I shouldn’t be using the chlorine tabs. Instead, I should be using chlorine shock daily because it will evaporate and not damage the fiberglass shell.

I’m a bit lost at this point and hoping for some guidance.

Thanks in advance

Thank you. I don’t think they ship to me but I’ll see what alternatives there are. What do you think about the chlorine tablets in fiberglass?

Tabs melt too fast in the hot water. The add CYA and also lower PH. We use Dichlor until CYA is 30 then switch to liquid chlorine aka bleach.
