Well, if you ask a lawyer, they will always say "oh use a heat exchanger!"  That way, if the water has heavy chlorine or sediments, there are no issues with the solar collectors and you can chase the heat exchanger supplier when things get clogged up.

But let us think about this. The manifold is copper, yes. There will be some reaction with chlorine water or salty water, just like with the copper pipes in nearly every house in America. Sure, copper will turn green and a bit of scale will lose some heat transfer efficiency--- but not as much as a heat exchanger. A heat exchanger will cost almost as much as a couple of panels. Will the manifold fail? No, no more so than the copper pipes in the house fail with the same water running through them for decades. If scaling is a problem, use a water softening agent or run some vintages through the system from time to time to clean out the calcium deposits.

If it was me, I would just run the pool water straight and go easy on the harsh pool chemicals.
