New pool new problems -- algae and iron!

[rebber4]

You are right. I meant to say calcium hypo. I will order the add-on tester tonight. Thanks so much for your responses and help. My pool is 20x40 so around 35k gallons. Im sure ill be asking more questions. Im tired of being so dependent on the store.

We'll be here!

Ok so I got home and added 3 lbs of 78% calc hypo and before my eyes the water is turning green. How can that happen? I retested every thing first. Chlorine 0 , ph 7.2 , alk 120, calc 210, cya tested below 30.

Water turning green when chlorine is added usually means there are metals in the water. Did you ever add that copper algaecide that you said you had earlier in the thread? (If not, don't!)

Well dang. Thats what I've spent soooo much money trying to get rid of. I didnt add the copper stuff. I did add some poly stuff( from pool store) no copper Sunday night and some mustard algae stuff Saturday. The water turned back bluish a few minutes after It had turned.

What was the mustard algae stuff?

[rebber4]

Im not sure because I threw the bottle away. It was store branded mustard algae treatment. I put in 3 lbs of calcium hypo last nght. waited 1 hr and put in 242oz of 8% bleach and added 11 pucks to chlorinator and skimmer. This morning my pool it very green. Test results 7 am today FC=1, tc=1.5, cc=.5, ph 7.2, alk=120, calc 220, cya <30. also i can tell that the liner is turning brown again, presumably the same staining that i have been fighting for 5 weeks, and it wont brush off. If it will help I can walk thru everystep, procedure, and chemical i have used along with what i was told st the pool store and post the test results from pool store throughout this grueling process.
