Hot tub clarity.

I have an 850 litre inflatable hot tub. I have to fill it from a well
which is a cloudy brown colour. I’ve tried a clarifier which hasn’t made much difference. Can anyone suggest something to give me crystal clear water? Thanks in advance.

looks like you need a filtration system goodness knows what is in the well water ,have you had it tested

Not yet, next on my list.

Pump the water from the well for 2 to 3 days.....should clear after.

Still will need to be checked for hygiene purposes could be full of worms
