This was one of the cheapest uv bulbs I could find but has actually worked better than any of the others I have used.
As recommended, I change my uv bulb in my pond filter every year or so. I have usually bought bulbs from local garden centres costing £12- £20, but the last 2 summers my pond has never been completely clear. I put this down to the fish having grown quite large and perhaps stirring up the muck at the bottom whilst feeding.
This year I bought a cheap bulb from Amazon and it made the water crystal clear! I can see the bottom easily. Not sure why the other bulbs weren't as effective but I will certainly be buying cheap from this supplier in future. It isn't often that a cheaper product actually works better than a more expensive branded one.
