Welcome to Castle Hot Tubs

AquaFinesse Spa Care

AquaFinesse Water Care In one simple weekly treatment our patented environmentally friendly formula gets to the root of the problem by loosening this layer of slime from the surfaces, it is then rinsed away by the action of the water and prevented from reforming. Result, a dramatic reduction in the levels of bacteria, needing only the minimal amount of sanitiser! Even calcium, the notorious destroyer of spas, is no match against the power of AquaFinesse. So there you have it! The perfect all in one hot tub & spa solution. Safe, clean and crystal clear water which protects the bathers, the environment and even the spa itself. Say yes to softer, purer water and a cleaner bathing environment. The AquaFinesse product range is vast and ranges from Spa Cleaning Tablets to Filter Cleaning Tablets.

Our Filters

We stock a wide range of hot tub filters, so understand finding what you want might not be the easiest task. That's why we have carefully labelled and organised our filters, so they can be easily found using our Filter Search Tool below.

Filter Search Tool

Use our filter search tool to search for filters based on their part numbers such as the products Darrly, Great Barrier, Unicel, Filbur, Pleatco, and OEM references. You can also search by the filter dimensions, the length and width in centimetres. Length is measured end to end and does not include the handle or screw piece, the diameter is measured across the width of the filter. [woof]
