I have an intex ultra 18x52 pool with 1600 sand filter with an added salt water system. I am trying to add cyanuric acid. The instructions say to add through the skimmer. Unfortunetly on this pool there is a strainer where the hose of the skimmer attaches to the wall of the pool and all the cyanuric acid clogs up right there. Any suggestions or solutions on how to add this chemical to the pool.
