I would certainly purify the lake water for use in flooded hydro but that’s just me.
Which I already stated.
It's not really so much that anything in there will hurt his plants as it is the fact that it will turn his ebb and flow into a slime factory from hell. That's just how lakes work. Anybody that's ever run an aquarium will tell you the same thing: it's a constant battle against nitrate, nitrite and ammonia. (These are all waste byproducts and are natural.)
The only way to fight it is by purifying the water, which of course puts him right back to square one.
