my parents have a pond installed last year that was built and setup by a semi-local landscaping company and i have a feeling that it is under filtered.

it is about 1100 gallons and is home to seven koi that range in size from roughly 13" to 17". in addition to my assumption that it is under filtered it has a problem with algae and is starting to develop green water do to the more intense summer sun.

for ease of use and portability i was thinking of getting them an FX5 and then building a outdoor shelter near the pond that we could set it in.

another reason i was leaning towards a FX5 is that i was hoping to get a good recommendation for a UV filter that i could hook up to the outlet of the FX5 to avoid having to purchase a separate pump to run the UV filter

so to sum it up,

1. Would you think a FX5 would be suffiencient to suppliment the current filter system

2. Do you think it would be a good idea to run a large UV filter off of the FX5 to help with algae or should i just get a seperate pump.

3. or insert a different suggestion here.

what is the the current filtration?

it currently has the basic pond skimmer that pumps the water up to a waterfall box that has two pre-filter pads and up through three mesh bags of bio-balls. im not exactly sure of the gph the pump has but it looks/feels pretty decent size.

and i know the FX5 wouldnt be ideal but i figured the additional filtration would be beneficial and it would be one more pump that i wouldnt have to buy in order to run a large UV filter. plus i am planning on wintering the koi in my parents heated garage in a big stock tank and i figured the portability of the FX5 would allow me to move the filter inside to filter the fish over the winter.
 
NEver use aquarium filters for ponds.

Besides, 1100 gallons with a 600 gph filter? Not at all.

Get the specs of the pump and take some pictures so we can see what the pond and filtration looks like.

Green water does not mean its under filtered. When there is high nitrates and phosphates, this will happen. The only way to control green water is using a lot of plants or a UV-C on the original pump, you do not need an additional pump. If you went with the Fx5, you would be adding an additional pump which is what you said you did not want to do. All the UV does is clump the algae spores together so it can either settle to the bottom or get caught by the filtration.

Green water is common because who wants to change 500 gallons of water weekly, bi-weekly or monthly? Have a balanced eco system is the best way and that is to use a ton of plants

In a pond you have tons of area for bio filtration and the skimmer box plus the water fall box will provide enough mechanical filtration.

You can buy a bigger pump, no big deal with that at all.
