Bought these bulbs to replace existing one as they recommend you replace them on a regular basis in order to keep the algae at bay, had to wait to see how effective they were before I could write this review. I have to say I'm really impressed, and they seem to be doing their job as intended the pond has remained crystal clear since. I could recommend them and will probably use the same supplier again. Excellent product.
