I agree, maintaining a pool is super easy. My assumption with the splash pad is that there must be some complication introduced because of the aeration of the water, and maybe the cycle time. Aside from raising the PH, maybe it makes it tough to keep the chlorine levels up even with CYA. I wonder if it would be feasible to build a splash loop that had an intermediate tank which could maintain better control over chlorine levels for a predictable amount of time that would make sanitizing reliable.

Maintaining a pool gets less easy as the amount of gunk added increases in proportion to the volume of water. A lightly used swimming pool? Not so bad. A lightly used swimming pool with an attached spa with spillover? Barely any harder, unless you care about maintaining a nonzero chlorine residual in the hot tub. Residential hot tub that doesn't spill into a pool and gets any amount of serious use? Utterly gross without real effort. And all of this assumes that you're just not concerned about cryptosporidium. The chlorine levels in a pool do not reliably kill cryptosporidium! So you need something like UV, which will kill it as it goes through the UV chamber. A splash pad has huge load of junk and a small water volume. The one nice property is that almost all the exposure is to water that is fresh out of the pump and associated filters, which makes UV quite attractive.

  Agreed, eliminating crypto in a typical residential pool is basically impossible. If I were sure I had a pool infected with it, I'd probably drain, disinfect as much as possible, refill, and then SLAM the pool hard with no CYA for a while. What a PITA. And that assumes the pool is the type that can be drained. The most reliable solution, of course, is to screen the people who are going to use your pool and don't allow anyone who has even a hint of crypto symptoms to get in. I hope that most public pools invest in a UV system. It's hard to prevent some dumbass with diarrhea from deciding today was a good day to swim anyway. Lots of those types of people in the world.
