Hey All,

 

I have a 6500L pond that has a shade sail over it so it only gets morning sun for about an hour (at the moment) and part sun (10%-15%) until about 2pm. I only have 4 (15-20cm) koi in there, fed 2-3 time a week and there is a small grow bed as well as 2 filter boxes (1 is 50L the other is 10L) there is also a 12w uv sterilizer. The water turn over is about once an hour (6500L/Hr). I was wondering if i could just some bristle nose it to help eat it up or there is a good fish that eat it and wont attack the koi?

 

thanks for any help!

Mollies eat algae and your koi will keep their numbers down, you will probably have to remove bristlenose in winter.

 

Cheers Terry

Phyto or bent his algae?
<br />
<br />If phyto chuck in some hay (dried grass), ~handfull every month or so, to provide a carbon source to change the nutrient cycle pathways.

Stop feeding the koi. They will eat some algae but not if they are well fed. If you stop feeding it will also reduce the level of nutrients for the algae to grow.

I spent a few years working at a commercial koi farm, i really like outdoor ponds :)

You can add in heaps more koi! They are uber good algae eaters and you can significantly reduce feeding, Morning sun is a good one for growing algae fast, great for lillys but not so great for algae control...

Put lots of plants in that will reduce the nuitrients for the algae to grow

Elbow grease - remove as much as you can by hand and large regular water changes

Unlikely,,,,,, but if you get a large terracota pot turned upside down with a little arch broken out of the rim so bristle nose can enter.
Stick a smallest size aquarium heater inside with a protector guard over it so fish can't sit on it and get burned.
The heater won't turn of for most of winter, so power bill may go up $10-$15 per bill.
The pot should hold enough residual heat for the little guys to have a winter lifeline.

Different micro climates in people's ponds are all different, some get super cold, some not so bad.
The ones not to bad are out in sun, but temp flucuations begin happening.

I found they slowed down and died off at around 16 degress. At 18 they were fairly lethargic, 20 they seemed reasonably happy and bred at this temp. They lasted almost a full year but died off in the very coldest month of winter. I suspect that they were getting some warmth from the internal pump, so what Buccal has suggested may work. It's worth a try, i suggest you give it a shot

Yeah intresting. I might monitor my water over this winter and see the temps. Its a missive concrete pond that about 4m x 3m and close to 1m deep so it hold temp pretty well and gets all morn8ng and early avo sun

Middle end of winter she will get cold, no doubts.
Larger and more stable yes,, hold heat better yes,, but once finally it gets to cold, then it will remain stable cold and hard to regain heat.
