475 gallons, how much powder "Ultra Shock" to use??????

[Shannon84]

That's what I was looking for, someone to tell me if it is simple or not to keep this pool clear by treating it. Then, I could make a more educated decision on whether to just empty it once or twice a week and refill or treat it. So far, cleaning and refilling looks like the safest way.
I certainly wasn't looking for any sciences to change their laws to suit my life (??), was just looking for answers to something that I was new at and needed guidance with, and asked a simple question about it being simple. When you're on your own with three little ones, you don't have half the day to spend on a pool, so you have to make sure you know the simplest way.
So refill, I WILL! I may try once to empty half of the water out that's in there now, add fresh water and a quarter of this bag of Ultra Shock powder. Keep it vaccumed and skimmed and add fresh water and the powder once-a-weekish. We'll see how it goes.
Thanks, Doc!

I'm glad you found something helpful here.

I find it frustrating that puddle pools are sold without any hint about how difficult it can be to keep them clean and safe!

If you limit the number of swimmers, add bleach as described, and drain and refill regularly . . . you'll be MUCH safer than otherwise. I'm not sure about the UltraShock -- so many pool chemicals now are compounded from a chemical 'voodoo soup', that know one knows what's in them, and some ingredients used can cause real problems.

I'd encourage you to use the PLAIN 6% bleach, instead of some "UltraShock" with unknown ingredients. Because of the way 'shock' is labeled, it may NOT contain ANYTHING that kills germs effectively!
