Hi Razz;

You could drain it, but you probably want to have a plan in place, and the tools (kit, chems) ready before you do.

It's not too hard to run an Intex pool, but with their tiny filters they are unforgiving of neglect or errors.

On your next run to Walmart, get 10 gallons of plain 6% household bleach, 4 boxes of borax, a 2# (approx) container of stablizer, a cheap OTO / phenol red testkit (you'll use this AND your Taylor), and a container of pH-Down (several pounds). You'll have to order a quart of polyquat and -- if you are filling from a well with metals -- a quart of "Jacks Magic" "Pink Stuff" online.

Also, you'll probably need 3" tabs and a floater. You can use the Walmart blended tabs -- just watch out for copper! -- but it would be better to have plain unmixed tabs, if you end up going that route.

With that stuff, and a Taylor kit, you should be fairly well positioned to either clean up your pool or start a refill. If your pool is not cloudy, I'd recommend staying with the water you've got. Test your pH and chlorine today, and post the results. But, we'll probably tell you to add a gallon of bleach late this evening -- within 2 hours of sunset, so it can work without being destroyed by sunlight.
