Reviews
What hot tub owners say
“I was sceptical at first how Aquasure could make that much difference but I was truly surprised, the water felt softer and silkier. It almost felt as if it had less resistance against you.”
“Really like the product, it makes maintaining the hot tub easy & less effort. The water quality is much better. The service was really good from ordering to receiving with updates at each step. Would recommend.”
“I have used Aquasure in my hot tub for 2-3 months and have noticed a difference in water clarity. No build up of oil/scum as sometimes used to happen with a lot of use. The spa does feel cleaner.”
“I've only given my hot tub two doses of aquasure so far and I can feel an improvement in the water quality, and it is staying clear so far. The water quality in my area is terrible so to date I am pleasantly surprised.”
“Received this product couple of weeks ago and I can definitely see the improvement of clearness in water. Instructions easy to follow - just what I need - and so easy to use.”
“Product is excellent, delivery is excellent. We received our new hot tub in December 2024, it's now June 2025 and it's the same water. Have only changed and cleaned the filters and water chemistry is perfect.”
“This company are always available to support whether you pop into store or contact via phone or email. Their experience is invaluable to hot tub owners/users.”
“This is the best I have ever kept my hot tub water quality with the minimum of work. I would strongly recommend.”
“Worth every penny. Thanks for your support, it really makes a difference to the hot tub experience.”
