For what it’s worth, UV lights in ponds do what they’re supposed to: keep the pond clear of algae. But, it’s only in certain conditions.
“Uhp, well I guess we didn’t meet these conditions then,” Bobby points out.
The algae has to flow in front of the UV lights for them to work. This means you’ll either need a lot of lights or more than one type of filtration.
You pond also has to have the right speed of water flow. If it’s too fast the pond UV lights won’t work. Getting it to the right speed may increase the cost of a pond.
Clear is clean, right? Ponds have more issues than just murky water. They also have dead organic matter like leaves and muck filling it up that can make it dirty. UV lights don’t purify the water either so it may be unbalanced and harmful to any fish and plants.
“So that’s why our pond hasn’t completely cleared,” Dawn realizes.
*Pond UV lights can also be a pain to clean and hard to know when to replace.
“Well, what can we do then?” Bobby asks.
