How can I remove the dead algae from an Intex 15' X 48"

Would I be better off getting this

And the Intex 1-1/2 adapters And another hose or the Intex plunger valve? Looks like the overall cost is going to be about the same.

This would be easier, but I don't know if it can be run partially closed.

I need to restrict the pump intake flow.

I'm not sure how the Intex valves are made; if they are slide valves, using them to throttle will work, but may damage the valve over time.

The ball valves would be much more suitable, but . . . Asian made no-name ball valves are TERRIBLE. I was a licensed master plumber for nearly 30 years, so I do know valves, and I have been totally bummed out by Asian made plumbing products sold by Lowes and HomeDepot. I'd recommend that you stay away from them, except as a purely temporary fix. Of course, that's pretty much what this is.

But, how are you going to connect them?
