Hi there,
We are new owners of an inflatable hot tub (Lazy spa Helsinki so a 6-7 person hot tub). We've never owned a hot tub before and I'm just not sure whether the chlorine levels are quite right. When I use a tester it comes out brown for chlorine (which apparently means there is too much chlorine), but the free chlorine test is a pale cream colour, indicating that there isn't enough chlorine. We are putting a few tablets in per week plus some granules. Any advice welcome.
Many thanks,
Sarah.
