## Description

Product Description This 11W UV sterilizer has a unique design which turbulates the water through a helix design so the water does not just run through the uv but spins inside allowing the UV more exposure before the water comes back out from the outlet. Enabling increased efficiency by a more even exposure of the water to the UV. The ultra violet clarifier continues to form a key element of a clear water system. Very useful if you want to run the output to a two-fall waterfall of a waterfall and a filter. It comes with 3 for small pipes and 3 for larger pipes, stepped hosetails, one of which is translucent so that you can see that the light is working, the light also has an end port so you can see that the UV light working. This unit does not come with a plug. Set Contains: 1 x All Pond Solutions CUV-211 UV Light Steriliser Clarifier Filter, 11W

Review: Easy and highly effective. Rapid results. - I've only got a small 100 ltr pond but it was pea soup, couldn't see the bottom. After installing the steriliser (7w, 207) which was really easy (doesn't come with a plug which suited me, just wired it into the exjsting pump junction box), the pond was clearing up noticeably within, 12 hours, could see the bottom in 24 hours, and the water was crystal cleae in 36 hours. Really pleased. Will save a fortune on clear solution chemicals. One thing that i'm not sure about is the uv bulb doesnt seem to be on all the time but it definitely works. Could be a built in timer i guess or it overheats on hit weather.
Review: Genial en mi acuario - Tenia el acuario desbordado de agua verde (por exceso de nutrientes que mis plantas no asimilaban), había llegado al punto de que no se veía ni la decoración ni las plantas y apenas los peces. Lo compre he instale junto a un filtro externo y en cuestión de 24 horas el agua esta cristalina, gran rendimiento.

### ⭐⭐⭐⭐⭐ This seller has really good help via phone
*by J***D on 24 June 2015*

This seller has really good help via phone. I wanted to know if it was a direct replacement for my deceased Oase Bitron 15 uv fitment. It is an excellent fit in the existing Oase filter tank and you can even use the existing tank water deflectors to secure it to the side of the filter. Took about 5 minutes to install which is a world record for me. The filter has a transparent band around the central tube which shows the UV light to be on and working with ease and from a distance. No more waiting until after dark and peering into an awkward little widow to check if the UV is on. Brilliant product and after 5 days the green pea soup is now running clear, happy fish and happy me!
