| the algae is the reason why the water is crystal clear. it pulls all the nutient out so that small algae cells will not be able to live there making the water turbid looking.
harvest the string algae- before you do anything. that way you remove some of the nutrient.
if you kill it off the nutrient will make its way back to the water.
your best way is actually to prevent the nutrient building up to that level next time. in doing so it will clean itself up all free of stringed algae and so indicate when you have it right.
you cant take away the water, well you could change some water out but the problem will only manifest itself again later unless the root casue is fixed. maybe you can take away some light but really its the nutrient thats the problem.
look at your filtration vs the amount of food going in. |
