Pump, filter, skimmer, vacuum.... This is a pretty fancy splash pool!!! Take a pic tomorrow and send it along.
Yes, the sun burns off chlorine. We just don't know how much protection (CYA) you have at the moment. I guess if it gets too high you can easily drain some water and dilute the CYA if need be. An advantage of the smaller pool size! Your decision about the floater. No worries!
