Blue Wave Large Floating Chlorine Dispenser for Pools, 2 pack

from PugsRFun

Larger than I thought, holds several 3" tablets of chlorine. Cover easy to twist off, easy to open/close the vents. Just fill, cover, set vents & put in pool. You're done.

I have had this in my pool for a few days now, and the chlorine output is perfect, and can be adjusted. it helps to conserve the chlorine tablets, saving me money. This product works so much better than adding the tablets to the pump.

I have two of these in my 20x50 pool using 3 inch tabs and it keeps the chlorine content at the right level even if I don't have the filter running. The dispenser is inexpensive and effective.

I had bought a different style that they sold in Walmart.I returned it to buy this one and am very happy I did.It's easy to use.Very easy to get the lid off,unlike the one I returned.Would recommend it to everyone.
