We've all had problems with it but how many of us have had a close up look at exactly what Algae is.
Basically algae are single celled plants, they come in two differnt forms the first we'll look at makes or composes that we commenly know as hair algae though others know it as string Algae.
This form is the easiest of the two to control and there are various ways of getting it out the easiest way is to buy a special brush that is designed to capture the strands and by rotating the brush the algae is snagged and can thus be removed.
The second form however is when the single celled free floating algae blooms which many describe as a soup where your koi totally disapear.
During the day the algae bloom is the same as any other plant in that it makes Oxygen and consumes carbon dioxide but at night its a different matter as the bloom now goes into reverse consuming Oxygen and producing carbon dioxide which we all know bodes ill for our charges.
What else does algae do well for one like all plants it will consume nitrates which we dont really want in our ponds. Now Here comes that classic catch 22 moment it needs nitrates to grow thus becoming a bloom which we dont really want so what do you do , have high nitrates in the pond and green water or do regular maintenance water changes etc and keep algae down so good husbandry is an absulute must !!!.....
Well for one we dont really want either in our pond so regular tests need to be done if your going to keep it down.
If however you do end up with that classic pea souper of a pond there are ways both natural and chemical to remove it .
How do we set about removing the algea ?
Barley straw bales or barley straw extract, we can also use hydra-Cyrstal to remove green water these are the more natural ways of doing things and should we get it this is what we would use.
We wont go into them but there are many other products on the market NTLabs make one of the better ones, as do other well known companies but mostly however they are chemical, which we dont really want as mistakes can be made.
So as you can see its always best to research your chosen way of removing algae you dont want any nasty suprises whilst treating the pond for it do you
Natural is the best way forwards in our eyes here is a link to Hydra-crystal :-http://www2.hydra-int.com/Videos/Hyd...o/CRYSTAL.html
I hope this helps
