Can't keep chlorine in my pool

[jgfranklin]

Well bleach is going to be the cheapest option at this point. How much do you think I should put in? My pool is a 29,000 gallon white plaster gunnite(sp) pool. I just checked the chlorine after having dumped 2.5 pounds of shock (not dichlor) in and it has basically almost disappeared again after only about 2 hours. I do have algacide in the pool that I put in weekly....I guess that stuff isn't working? My pool water looks so beautiful...just no chlorine....it is rather disappointing and very frustrating!

I just used The Pool Calculator and it is saying about 7 gallons of bleach...if that sounds reasonable, let me know...I'll add it tomorrow night and then see how the rest of the week goes. It is supposed to cool down a bit anyway so we can stay out of the pool for a while. 15 ppm....man that's a lot.
