You can almost certainly switch without draining.

As a rule, draining is only necessary if you've used PHMB (Baquacil, Softswim, Revacil, etc) or a copper/silver system. And even then, it's not always necessary so much as just easier, when working with small above ground pools like yours.

But, you'll almost certainly need the Taylor K-2006 sold by Amazon if you don't already have one. And if you want to 'get it all' now, you'll also eventually need refills for the CYA test: 16 oz bottle of R-0013 and Disposable plastic lab funnels. Try to order from Amazon rather than a 3rd party selling on Amazon: Amazon handles shipping and warranties MUCH better.
