The water hose going from the seacock to the strainer is getting hard growth built up inside it. It necessitates removal, lots of banging, and rinsing. I used standard reinforced water hose. Is this the wrong product?

I did the clr, it helped a bit. cleaned my new bilge pump with it too. got that minor scale gone quick.
