The Kokido Thermo-Klor floats in your pool or spa and releases chlorine or bromine there gradually. You twist it open, put tablets in, click it shut again and let it go on the water. Tablets up to 3 inches fit inside.
On the side runs a thermometer strip with both a Celsius and a Fahrenheit scale, so you can see in passing how warm the water is standing, without fetching a separate instrument for it.
The ribbed base twists further open or further shut. That sets how much water flows past the tablets and so how quickly they dissolve - handy to adjust with the season, or with how heavily the pool is being used.
The floater is supplied in an assorted colour: blue, lime green or orange, each with a blue base. Which colour is in your parcel is not something we can fix in advance.
