We have been using Aqua Kem Blue for the past 7 years, we spend about 150 nights away each year so have used many bottles!!!
We have tried others but this comes out the best for odour, and effectiveness in braking down the contents..
We shop around the shows and buy several bottles at a time, at the moment we find GO Outdoors the cheapest supplier.

Tried them all over the years,always come back to this.More expensive but goes further,so best value for money.Most effective too.
