A UV is not the total answer to your green water. feeding, sunlight,
water changes, bio load, plants in water etc all have a diverse part
on algae. Take away phosphates or nitrogen or sunlight and the stuff
dies, so the main item you want to lock up is phosphate.......si the
single celled algae can not use what it needs to bloom and grow and
winds up dying. Algaecides are ot a good idea either. as it reduces o2
content or can kill a biological filter in the process.

Take a wad of regular old polyester batting and shove it in the
filter, and keep check onit as its capable of removing the algae
cells. Water changes are a definate help.

UV will clean up green water, but most folks fail to keep up regular
needed water maintenance and soon the UV gets overwhelmed further down
the road. The best place with prices for decent filters and UV's is AZ
Ponds........and most prices also include free shipping.
Bear in mind the UV bulb needs tobe replaced every year or they do not
work right, and some of the bulbs can be pretty pricey......Years
back UV's in thjis region used to be a big time thing, now they are
rarely seen in use.

Provide shade for your pond unless its at least 60% covered with water
lilys or other aquatic plants. Cheap feeds add to the green water
problem as does over feeding. Wrong filter media does little to remove
cells......and nutrient rich water helps the stuff grow almost over
night.

Hi! We just purchased and moved into our first home, and it came with a
pond. We have 2 big Koi and several smaller goldfish. About a week
after being here, our water became very green and we can't see the fish
anymore. Earl May came out here and told me we needed to use some "Algae
Fix" on it and also think about getting a UV light. He said they run
200-300 but after looking on the internet I don't believe him--maybe
they are higher in the store?

Our pond is roughly 1500 gallons. I do not know how many gph it does
but the guy from Earl May said it was a good pump and skimmer. I belive
it's made by Easy Pro.

So, can someone refer me to a good, affordable UV light for our pond? I
can answer any add'l info you need maybe, we don't know a lot about this
pond!
