about a month ago I had a swimming pool installed at my house. It is a fibreglass pool and the installers had it filled 2/3 with water during installation to get the inside outside pressure equal.
It started raining and kept raining for about a week. When the install was completed and needless to say, the water was really awful, I asked the installer, well actually insisted that I want to clean the pool, you know......it would be my first pool clean.
First I start of getting all pH levels right and once that was done, I ran the pump for 36 hours, Friday 18:00 till Sunday at roughly 06:00.
All excited about my "supposed to be clear by now" pool, I woke up early that Sunday morning and to my utter disappointment, there I stood, starring at a dull creamy cloudy pool.
What I did next, worked like a charm......
I went and bought hth Xtreme Floc and poured half a bottle into my pool and ran the pump for about 3 hours on circulation to get it all mixed up a bit.
I left the pool standing for about 12 hour so that all the particles drop to the bottom (DO NOT switch on your automatic cleaner, it will just mix it all up again....I did and I had to wait again)
I took the inlet pipe and carefully sucked up the thick layer of "coffee" on the bottom of the pool to waste. I continued to about where the water was 2cm above the weir.
I then topped up my water to the correct amount....I think, 2cm under the top of the weir and ran the pump for 6 hours. By this time it was already much better, BUT I HAD THAT PARTICLES YOU ASKED ABOUT!!!!
I then added a floc block in the weir and ran the pump like normal (it makes the sand in the filter sticky, thus catching almost all those particles floating around)
Lastly, someone told me to put a thick sock on the outlets to catch the real fine ones and I must say, that helped a lot.
I am no expert, but this worked for me.
