Hi i am new to the forum, and was curious if anybody could help me.
Last year i took over a pool route that my parents had run for about 20 years. The first summer was very stressfull, constantly fighting algae despite very high levels of chlorine. My parents only suggestion was to keep using more chlorine and alaecide's and clean the filters, however this is very expensive ( some pools i am adding 8 3 in tri-chlor tabs a week plus di-chlor and algaecides). So i have been trying to do some research on pool chemistry to make the business less stressfull and more profitable. I believe that the problem i am having is that in almost all my pools the CYA is very very high,(my test tube only goes to 100 but it is well above that). It appears that the only solution to the problem is to switch to liquid chlorine, however i dont know how practical this is because how bulky liquid jugs are, and the fact that i only go to a pool once a week. I do not know very much about liquid chlorine, so if anybody has any advice about switching from tri-chlor to liquid ( or perhaps a hybrid) i would appreciate it very much. By the way i run about 50 pools a week, in a very very hot summer climate.
