I'm trying to switch to BBB. My levels were all wrong, and I'm pretty sure I adjusted them in the wrong order so everything got a bit high. I don't think that should have affected what I'm seeing, but maybe so....
this afternoon I added 1 gallon of 10.5% bleach (from pool store, was told it was fresh this morning). I tested with OTO kit after 30 minutes (giving it time to circulate). I had a dark yellow color. After 30 more minutes, barely a trace, and DPD said 1ppm FC, 1.5ppm CC.
This past weekend, over a 15 hour period I added 2.5 gallons 10.5% bleach, 2 pounds 73% calcium Hypochlorite, 1 lb dichlor. A couple hours later, OTO said barely detectable chlorine. How could it go away that fast? Pool is sparkling, BTW.
cya 60 (I thought hot Florida sun was baking out my chlorine, so added cya to bring it up from 30. Probably not best move.)
ch 510 (I believed pool store when they said my CH was low, and added 15 lbs CH. Definitely a bad move -- and why I bought TF100).
ta 120 (I brought it UP to 80 with baking soda before adding boric acid. Probably not best move).
borate 80 (I brought it up to 60 before adding borax to adjust PH from adding cya. Probably not best move).
ph 7.5 (brought up from 7.0 with borax and washing soda before adding cya, then more borax after cya).
all tested with a TF100 that is about a week old.
My regime over the past year was to toss in a pound of dichlor w/copper (aquachem blue) every week, which actually did a pretty good job. I'm in Florida with solar heat, so pool is open year round (though 3 or four months of that it is a bit on the chilly side!). I ordered a Stenner to feed bleach, but if I can't get chlorine to stay in the pool I don't think I can feed it fast enough (not to mention the expense).
any thoughts? Maybe if I keep pounding the chorine (ie slam) it will eventually stop?
