Floating Swimming Pool Chemical Dispenser

It has been in the pool for a week and the chlorine tablet needs replacing but although the lid turns I can't get it off. I tried drying it so it would be less slippery, but it makes no difference.Updated to add that I persevered with trying to remove the lid and finally succeeded. The trick is to press down very hard on it - this enables the lid to turn that extra bit so that the markings line up.

supplied unit was not as pictured, pretty sure it would still have been effective but I was looking for a range of designed and the one supplied was the same as one I already had. The picture needs updating. prompt reply and rapid return and refund so credit to the seller for this.

Great item for helping to maintain your swimming pool.By simply putting chlorine tablets into the lid at the top of the dispenser, the tablets then dissolve inside the dispenser, the chlorine is then released gradually out the slots near the bottom.The dispenser is easy to use, clean and store.
