Please Help Me With A Clorine Problem

[fedup321]

I am new to the forum. As a pool owner for 24 years, I have run into a problem that I have never had before! After opening the pool, I took a water sample to my local pool supply company - at that time they said that I was good to go - add three packs of shock and I needed nothing else! Water, as usual this year, was green and dark and dirty. Next day I took a sample - no clorine reading. In the past, I have been told to add at least ten packs of shock, which I did! The next morning - no clorine reading! I used all of the 25 lbs. of shock = still no clorine reading. Took another sample today to the pool dealer. This time they told me that I needed 27 lbs. of alkilinty and for me to put 25 lbs. of shock when I got home and 25 more pounds the next day. That I had to cross that plato of getting a clorine reading. After $190 so far, and by what they said - I am going to be spending another $160. for shock as they suggest. Today I was reading the forum and noticed that something I have never done before, by adding 6% bleach instead of shock. I have a 20x40 foot inground pool, holding 30 gallons with a vinyl liner. Can someone please give me info of how many gallons of clorox that I would have to add to equal to 25 lbs. of powder shock so that I can save money?

Before you start going crazy with the chlorine why don't you post a full set of test results. It is obvious that you are fighting some sort of algae bloom. I also suspect that your CYA is very high. I also suspect that you have been chlorinating your pool with trichlor tabs. This chart explains the chlorine/CYA relationship and it is by the man who first put this info out for us, Ben Powel of PoolSoluitions and PoolForum.

Thanks each and everyone for your response.After calulating I added 10 gals of bleach 6% and this morning I finally has a reading on my otc tester. It is reading at the top level same shade of yellow. now I can get to work on other chemicals to start the clearing process. Savings? $17 dollars for the bleach abd shock would have been 160.00 If I had went by my dealer recommendations 50 lbs of shock. Thanks again

next step is to get yourself a Taylor K-2006 test kit if you don't have one.
