Liquid shock, bleach, liquid chlorine?

What is the difference in the above? When ever I think I have it right I read something here that contradicts my understanding. Same thing with FC, TC, and CC. I use a Taylor kit and the chlorine reading is dark red for the FC and TC which leaves a 0 for CC, (FC-TC=CC) correct?

Thanx

Concentration. Bleach is usually 5.25% or 6% sodium hypochlorite. Shock is usually 10% or 12-12.5%.

FC+CC=TC

They are all sodium hypochlorite solution, all the same thing.

Grocery stores sell 5.25% and 6%, discount houses sell 3%:mad: and pool stores sell 6%, 10% and 12.5% but call it liquid chlorine or liquid shock.

1 gal of any concentration will add exactly that same number to 10,000 gallons of water. 1 gal of 6% adds 6ppm, 1 gal of 12.5% adds 12.5ppm.

That's what my pool builder said...he told me that there was lye in bleach, and not in pool chlorine.

Of course, he also told me that the trichlor tabs would each add the right amount of CYA for that amount of Chlorine, and I would have to keep using them to keep my CYA in the correct range.

He also told me to call him in the summer when I get the mustard algae like everyone else he knows gets, and he would put some copper stuff in my pool that would take care of it.

I got a little mustard last year, and knocked it out with the laundry bleach that will eventually ruin my liner :D

Never! They tell you that it will raise your total dissolved solids to unacceptable levels!

I hope you figured out that your PB should never again be allowed to do any maintenance on your pool.

Follow our suggested rules for maintenance and you should NEVER see mustard algae at all.

If you need copper to kill algae you've waited too long anyway--IMHO.

Actually Namco carries a revolutionary new product called "Econo-shock"... guess what it is?

I've been calling around trying to find "car boys" of chlorine here in the Denver area and someone finally told me it's against the law to sell them here. That would explain why I can't find it. I have a connection with a chemical supplier for 10% in a drum, but he says I need this fancy 4-pronged wrench to open it and it would cost as much as the bleach for the entire year. Guess I'm stuck going to WM and lugging for another summer.

You mean like this one for $8.49? http://us.st11.yimg.com/us.st.yimg.c..._1948_55874268

You can get them many places for less than $10.
