Need to get CL up...how?

[fireman0136]

CL 0 BR 0 PH 7.6 FC .5 CC .5 TA 110 CYA 30 CH 270

Not sure how much it rained lately since we were on vacation. But I do know it rained. I need to get the CL up. Can I use the hth shock n swim to get it back up? And if I do, how much of the 16 oz and how soon can we swim?

You def need to get your FC up or you know what's about to set up shop. For a CYA of 30 you need to keep it at 2-6 ppm.

Use bleach to raise it would be the obvious answer

You could use it, bearing in mind that that 16 oz package of 53% Cal-hypo will raise FC by 19 and CH by 13, and you're already near the upper edge of CH and you don't want that SWG element to start scaling.

If you plug your numbers into http://www.poolcalculator.com/ you'll see that about 1/4 of the bag will raise FC to just about 5 FC, which is a good number for 30 CYA. You really should learn to use http://www.poolcalculator.com/ ; having someone else tell you what to put in your pool is, frankly, how you end up pool-stored.

You can swim as soon as the stuff is mixed with the pool water. Dissolve it in a bucket, then pour it in front of a return and let it circulate. A better idea is to give one of the kids the brush and tell them to brush the walls, and when they make a full circle, they can get in.

As an aside, if you raise the CYA level, you probably won't lose so much FC to the sun, and the level will stay up better.

Richard is correct as always lol if you use bleach pour 27 ounces of 8.25% in and it will give you fc lvl of 5 also.( im a huge proponent of liquid chlorine)

In your case, I would think a little dichlor, IF YOU KEEP TRACK OF HOW MUCH YOU ADD, wouldn't hurt. A CYA of 30 is low for a SWG, and if you get it a bit higher, like Richard said, your SWG will be able to keep up better. The effects of adding chemicals section of the pool calculator will tell you how much CYA dichlor will add.

I too think your cya level is too low for a swg. See: http://www.troublefreepool.com/pool-school/water_balance_saltwater_generator With that said, make sure you don't need to kill off an algae outbreak...you would want to do that before raising the cya up to 70-80 ppm.
