Hi, can anyone tell me why I've got problems with blue green slime algae

and

black hair algae?. the blue green algae's got so bad that after only three
days it has recovered eight square inch's of the gravel in my tank and has
grown back in every place and more on my plants!. I no that I have not

been

over feeding or over stocked the tank with fish. the nitrite and ammonia
levels are at zero. the nitrate never gets higher than 5 mg/l and the
phosphate is around 0.25 mg/l. I guess that the
ph number is high and also the gh level because of the local water coming
from reservoirs on chalk/lime hills near my home, but I have not tested

for

those. the tank is out of direct
sunlight and has the standard juwel lighting and reflectors that come with
there tanks. I've been thinking about replacing a few of the plants with

the

fastest growing ones that I can find, but I think that unless there is a
treatment for blue green algae that will kill it off completely it will

just

start to cover the new plants, and I will be forced to remove all of them.

oh, and I change 25% of the water in my tank once a week, and I also clean
the gravel once a week with a power gravel cleaner. and my tapwater reads
zero for nitrite ammonia and nitrate and 0.25 mg/l of phosphate. thanks





I've had that, when the tank was still new. How long's the tank been
going? what size is it? How many fish/what size, and how densely
planted is it? How long are the lights on for?

I managed to eradicate mine by hoovering up as much as I could daily,
and doing a black-out over the weekend for several weeks, allowing the
plants (and hoovering the BGA) between stints.

That and upping the filtration/current flow seem to have worked a treat.
