Is the Mermaid something like the Frog?
It is suppose to fit into your skimmer but it is too big to fit inside my skimmer so I placed it right next to filter intake where that is the second best place to put it according to the instructions. It came with 2 suction cups that you put on the back of it and you just stick on the side of the tub. I don’t like floaters either that is why I went with the mermaid.The main reason why I went with the Brilliance bromine is because it is 100 % chlorine free. I have been having issues with my skin like itching and red marks. I made posts about it over the winter and every one thought is was because of dry skin, now it is summer and I still am having the same skin problem so I wanted to try something with out chlorine to see if that is what is causing my problem.Keep your fingers crossed.Capmorgan
