Hello my name is Amo I live in walsall England, I have been keeping koi fish for about 2/3 years with not much problems really. I have moved house and build a raised pond in my new house it measures 4m x 2.4m x 1.5m in all but I have put a filter in the one end with a bottom drain and the pond itself is 2.8m x 1.8m x 1.5m it holds 1080gallon. I’m finding it difficult to keep this pond clean as the water has turned green I am useing a filter chamber system and 25w uv but doesn’t seem to clear this up? I’m I doing something wrong?

Welcome to our group! I keep green water at bay by having a lot of plants and filtering with plants. How much do you feed them?

How many fish do you have?

Hi addy1
Thanks for replying I feed them twice a day at the moment once in the morning and once in the evening. I have about 15 fish which 6 are koi and the rest are shubkins and gold fish, I build it and filled the pond about 3weeks ago then added my fish from the old house. But the water has gone green now, I’ll put up at photo of filter set up when I get home just to show you. I need to know if I’m doing the filter and uv right or have I missed something?

Ps. The pond is in full sun light so I have covered part of the pergola with closed netting to shade it.

Hi and welcome @Amjad Rafiq

I totally agree with @addy1 , more plants=less algae!, also "3weeks" is kinda new, perhaps it needs to run a bit longer to stabilize

Hello and welcome!

Sounds like your pond is new, so probably suffering from “new pond syndrome.” IOW, there aren’t enough beneficial bacteria yet to keep the ammonia and nitrate under control. The algae is there because of the excess nutrients. But no, adding beneficial bacteria won’t help. Adding plants will help. Cutting back on feeding will help.

It also sounds like you might have too many fish for that space. As a general rule, it’s recommended that 1000 gallons is OK for maybe 1 or 2 koi. Koi, especially, produce a lot of waste, and with an overstocked pond you need a lot of filtration. And, as fish grow, they will produce more waste.

Are you testing your water? If not, you might want to get a test kit and begin monitoring your ammonia, nitrites, nitrates, and pH levels.

And BTW, while we humans don’t particularly like green water, the fish like it (as long as the water quality is good). Love your pond!

Hi Mmathis thanks for ur reply, i understand what ur saying but in my last pond I had 1000gal pond and ran that with a 8000 hoselock pump and 15000 fishmate pressure filter with a 13w uv built in.it worked fine and I had no problems with the pond at all. For this pond I bought a bigger filter (see pics) But I’m not sure if its set up right I have put a 1 1/2” gravity feed bottom drain to the filter on this pond and running that through the 15000 filter aswell then the 25w uv which will go to the water fall when that’s in.
So I need more plants to get rid of nutrients and test the water regularly... ok I get that.
Have a look at my set up do you think it’s set up right? Or do I need to run it differently?

Welcome @Amjad Rafiq As others have mentioned it will probably just take time for everything to balance out the water should clear up once that happens. As far as your filter set up goes it is a lot more involved than mine so I wouldn't be able to comment. The pond looks really nice and I hope you get a lot of enjoyment out of it once it's established and clear!
