We are in the UK and have an indoor in ground pool - 70,000 litres.
I opened it last weekend.
Shocked it and got the PH right. Added some chlorine.
The PH and chlorine are good, but the water was slightly cloudy.
I had a bottle of clarifier which contained this POLY ALUMINIUM CHLORIDE PWD 10-30%
The instructions said 3l for 50,000 litres. I put in 3l ( for 70,000 litres) as it was not that cloudy).
The cloudiness has got worse and is not really showing any sign of clearing.
The filter is clean backwashed and has run 24/7 for the last 4 days.
I suspect that the clarifiyer has caused the issue - either too much of it or a reaction with something else.
The question is what now!
I assume I will now need to add another chemical (flocculant? ) to try and solve this, but until I get some decent advice don't want to do anything!
The pool has no history of water problems - it is normally clear. I used a different brand of clarifier once when the pool got dirty following extensive cleaning of the surround. This just cleared it up. The amount used however was much less ( say 0.5 of a litre - but it was a different brand).
Any help appreciated
