lara3 Posted October 1, 2012 Report Share Posted October 1, 2012 What can i use thanks? i have a good filter with uv light inside (steriliser). Was just wondering what i can use if anything to get rid of the green? In summertime i could probably empty it weekly (i was last year) but feel this is a bit much sarah Quote Link to comment Share on other sites More sharing options...

Godly3vil Posted October 1, 2012 Report Share Posted October 1, 2012 I think you need to replace it quite often. Quote Link to comment Share on other sites More sharing options...

F15hguy Posted October 1, 2012 Report Share Posted October 1, 2012 best way to keep a pond clear is provide heaps of water movement Quote Link to comment Share on other sites More sharing options...
repto Posted October 1, 2012 Report Share Posted October 1, 2012 uv sterilizer of the correct size should do it?work out the volume of your pond and get the appropriate size uv .Bulbs have a limited life span and need to be changed yearly,that reminds me mine must be due for a new one.

lara3 Posted October 1, 2012 Author Report Share Posted October 1, 2012 Yeah thats what i thought. I changed the bulb 3 months ago. Pretty sure i have the right filter its a hozelock bioforce UV. I brought news sponges and uv bulb for it 3 months ago. A friend of mine says a uv light wont kill algae just the spores. I brought the filter as i was told by a few people that the uv light helps to keep the water clean and that it kills algae thanks sarah Quote Link to comment Share on other sites More sharing options...
lara3 Posted October 1, 2012 Author Report Share Posted October 1, 2012 Its a hozelock bioforce uv filter and titan pump. Keeps the water moving when its on sarah Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted October 1, 2012 Report Share Posted October 1, 2012 Best to leave the kahika where they are as they are pretty endangered and generally die when removed. The ones in the shops are pinched from the wild. Quote Link to comment Share on other sites More sharing options...
repto Posted October 2, 2012 Report Share Posted October 2, 2012 there is a formula to go by.the pump must be big enough to shift the volume of the pond over a given period.The uv does kill the algae and alot of other things ,bacteria etc.As the light intensity and daylight hours grow longer you can`t afford to turn it off at all,maybe at night when its dark?

Insect Direct Posted October 2, 2012 Report Share Posted October 2, 2012 could also grow some juncus pallidus (or any fast growing pond plant) down one end of the pond. it forms a good mat you can just thin out as it grows out over the pond. https://www.google.co.nz/search?q=juncu ... 00&bih=785 cyperus also grows well in conjunction with the above. adding duckweed and or azolla to the pond as often as possible also helps. red ears will eat it too. plants suck up some of the excesss nutrients and cut out light = less to feed algae. longnecks love making tracks all through the juncus too :smln: Quote Link to comment Share on other sites More sharing options...
