I was particularly impressed by the foam-filled construction, which provides a level of buoyancy that standard plastic holders just can't match. The walls are 40% thicker than the competition and feature UV resistance, meaning you won't be replacing a brittle, sun-damaged unit by mid-summer. It holds up to five large tablets, which significantly cuts down on the hassle of constant refills. Plus, the twist-lock cap is a total lifesaver for preventing those dreaded chlorine stains caused by tablets accidentally escaping the device during a heavy splash.

They are incredibly versatile, functioning perfectly in saltwater systems, skimmer baskets, or floating dispensers. While these tabs do the heavy lifting of killing organisms, you should still pair them with regular testing to maintain that ideal 1 to 4 ppm chlorine range for the best results.
