When contacted, the seller ‘Denny Enterprise’ sent a very non committal, dismissive response so will definitely not be buying products from them in the future & would recommend others give them a miss too!
Lay-Z-Spa sell a 1KG tub for £19.99 which is only for 50 chlorine tablets, so for 250 tablets it would've cost me £99.95 but it only cost me £39.82 which works out at about £7.96 per 50 tablets. Absolute bargain if you ask me...
These tablets are authentic and do a great job keeping my hot tub chemical levels correct. This tub will last me a very long time as I only tend to use 2 tablets per week.
I don't understand some reviews showing incorrect contents arriving and personally must say that this is not the case for me and that what arrived is what I ordered.
I'm very satisfied with my purchase and highly recommend for hot tub users.

Everything is ok nobody has had any unwanted effects everybody’s happy.
3 years on still alive pool is ok. About 2 weeks before I am ready to put the pool up I have a large gallon container which I put 3 of these tablets in with water. Once I have filled the pool I pour in the water from the container into the pool catching the tablets and putting them in the floatation device. It really give a good head start for the pool. 😎
Well you had better make sure that the chemical levels are correct or you will either end up with instead of bottle blonde hair, green flowing locks or a terrible infection from under dosed water.
And these little sticks will keep you on the straight and narrow. Simply dip in the water daily and compare to the colour chart on the side of the storage container. A few seconds later you know what the condition of your pool is.
Unless it's already green and full of gunk, in which case best you empty and clean it... Likewise if you get up in the morning and find the area surrounding your spa covered with dead small animals and birds, you've probably been a bit heavy on the chlorine. Best you avoid the area for a bit.
Overall, simple, easy and idiot proof.
I’m guessing they have put different tablets in a clear water tub and selling as clear water. Breaking every trading standard rule going I think 🤔
Think this selling should be checked out!!
