Got rid of the algae now cloudy

Postby Brian87gt » Thu 04 Jun, 2009 21:24

Got rid of the algae, now the water is very cloudy. It is a 10,000 gallon above ground with a sand filter. How long should it take for the sand filter to get the pool clear again? Would it be quicker to floc it? Here are the test reading from yesterday,
FC 1.4
TC 2.7
CC 1.3
PH 7.4
Hardness 0
ALK 81
CYA 30
I shocked it after I got the readings.

Keep the pool at shock level, which with a CYA of 30 ppm is 12 ppm FC, and MAINTAIN that chlorine level by adding more chlorine as needed. Brush and filter clean/backwash. A pool will usually clear within a week, often 3-4 days, if circulation is good. See this post as an example. However, if you have a weak pump or an above-ground pool with no floor drain, then it can take a long time to clear and the use of a flocculant with vacuum to waste can be used to clear the pool more quickly. With a pool with decent circulation, the flocculant is not necessary.
