How many gallons of water does your pond hold?
This is the first thing you should put down on your list when you want to identify those factors that will play an active role in the choice you will make. You will notice that most manufacturers will not hesitate to say what water capacity their UV sterilizers can deal with. This is your starting point
Do you own a 2,000-gallon pond? Then a model with a UV light bulb of 15 to 20 watts may be the right choice, provided that you have a moderate amount of fish living in there. In case your pond is more crowded, and there is quite a lot of waste produced by fish and plants, for the same water quantity, you should get a 40 to 45-watt model.
There are models powerful enough to purify ponds with up to 8,000 gallons of water. While the wattage of the light bulb matters, don’t forget that you should look at other things, too, such as the flow rate.
The efficiency of the light bulb must meet the capacity of the product to ensure a proper water flow rate. The higher the flow rate, the better the chances to eliminate more waste and bacteria from the water. Remember that this tool serves for purifying the water in your pond, and it needs to be as efficient as possible.
You should aim for high-efficiency bulbs
UV lights can be damaged during transportation. It all depends on the manufacturer’s care on packaging the model they will ship to you, and if they don’t bother to make sure that the unit you ordered gets in one piece at your doorstep, you might not be pleased with the quality of their product, either.
Read the reviews of UV pond sterilizers written by other users, to see if there are such issues. Once you have this aspect clarified, you can take a closer look at what kind of light bulbs are provided. It is preferable to go for high-efficiency bulbs that can work for an entire year, without fail and without needing a replacement.
The good news is that you can easily find replacements for broken or expired bulbs. Today you can find online all sorts of items, from a glass funnel to lab equipment and items you can use for your pond. So, there will be no issue with finding a bulb you can use when the one delivered with your purchase no longer works.
