Hi...first this might be long so I apologize.I had a pool installed in 2005 here in Southwest Fl.I was never quite sure how many gallons it held.I had thought 13000 but now I think it's between 8500 and 9000 gal.
Anyway the first summer everything went great.2nd summer I had some algae issues.Pool store gal had me using yellow out and yellow treat.There was some success but I always had to keep on top of it.
Last year aroung early march I began to get the streaking spotches of yellowish,brownish and black....all over the pool floor.Pool lady had me buy a case of dichlor granual ilb packages.I added this and pool becaome cloudy and murky.Then she said more chlorine.None of this worked.I decided on my own that this must be a black algae and not mustard...so I got a copper algaecide.....and thast seemed to clear things up.
I came across bbb here so I decided to try it.withing a day after adding 4 boxes off 20 muleteam borax...the water is crystal clear( this is end of last season)The water sparkled....but my chlorine was unreadably high....my ph was holding steady at 8.4.Still had faint streaking stains on the floor.
It's a spraycrete pool with pebbletech plaster....and it remained this way.
I ran pool pump several hours a day during winter and occassionaly added a jug of chlorine.It stayed clear all winter.
This spring the water reach 78 early....1st week of march.So I got my teast kit out and my free and combined chlorine was still off the chart high....the color was dark amber.
I just went to a pool shop that had a computer testing....found out my cya was 100....I know it was way higher because of all the dichlor and I use trichlor pucks in a floater.I had dumped a gal of muriatic acid in the night before and it did bring ph down to 7....and my calcium hardness was 480.
So i rented a sump pumpand drained about half the water and refilled yesterday.While the water was low I got in there with a ss wire brush and tried to brush the streaks of the floor.some of them did brush away but there is still a lot.
Anyway.....I added 2.5 gal of liquid chlorine last night....I put 1 gal of muriatic in this morning about 1 hour after adding a box of borax.
I waiting a few hours before retesting.
Am I on the right track here? I was so amazed at how clear the water was even though the chemistry of chlorine and ph were off.So I decided tostart out fresh doing bbb.
Should I add cyanuric....or continue with the pucks....or do away with the pucks entirely?
Thanks for any advice you can give me.
