Water getting slighty cloudy, any ideas

[Watermom]

I wouldn't use the HTH tablets at all. We don't recommend any type of algaecide except 60% Polyquat and even then, most pools don't need it. I never use it in my pool.

The other trichlor tabs that you have --- check the ingredients and make sure they don't contain copper. If they don't, you can use them but you can't shock a pool with trichlor tabs. To shock the pool, you can just use bleach. What is your volume?

Really? I have a hug tub of the HTH tablets and rather not dump them.

Volume ~14000 gal

How much bleach do I need to shock with?

[Watermom]

In a 14K gallon pool, each quart of 8.25% bleach will add 1.5ppm of chlorine and each of the 121-oz jugs will add about 5.5ppm. Shock level is based on your CYA reading so with a CYA of 30, you'll want to add enough bleach to take your chlorine level up to 15ppm.

Should I use a stabilizer also? Can I use Diclor instead of bleach?

[Watermom]

You can use dichlor instead of bleach to shock with but just be aware that most dichlor that is sold these days has unwanted stuff blended into it. Two that we know of that are safe to use are listed on the following page. http://pool9.net/ssr/

If you use trichlor or dichlor, you won't want to add the stabilizer since both of those products have stabilizer (CYA) in them already.

Hi there,

I picked up some bleach to shock with. I do have a gallon of Poolbasics Stabilizer, Cyanuric acid 25% Inert Ingredients 75%.

Should I add the stabilizer with the bleach, or before, then add bleach?

thanks

Also When you say "to take your chlorine level up to 15ppm" do you mean FC or CC?

thanks again

I have never seen stabilizer sold that was only 25% cyanuric acid. Not sure about it. Let me ask Ben about this. And, take chlorine up to 15ppm FC. You certainly would not want CC that high! Ideally, CC is 0.
