Hello Everyone! I just joined today and have some concerns about a green pool. Yesterday Oct, 10 2009 I checked out a customers green pool. I am still very new at this, so please bare with me.
The chlorine level was 0, ph 8.0, TA:90;Calcium 170; and cya 60ppm. This was using the Taylor Complete DPD Test Kit K-2005.
First I cleaned the filters, and then I brushed the walls and steps. I then proceed to add 8gallons of chlorine(Probably too much), 1g of Muriatic acid(Definitely Too Much), and 8ozs of dropout(recommends 4oz per 10,000g). The pool is approximately 20,000g.
I then let the 3/4hp pump circulate the water for 18hours. I went back today and tested the water. There is no FC and the ph is 7.0. The water is not as green but still present. So does that mean that the algae consumed the 8gallons of chlorine with a 10% chlorine percentage? Based on the size of the pool, should I add 3 more gallons to help kill the rest of the algae, and have it circulate for only 7hours based on Pentairs Energy website? And if and when I add more chlorine and cycle the pump again, will the dropout that is in the pool do its job after another cycle?
Thank you for any insight on this.
