My aquarium has now been infested with Cyanobacterium algae for about half a year now
and i've tried everything under the sun, apart from this.
"Blue-green algae" is not really a true algae at all, but Cyanobacteria - a group of bacteria capable of photosynthesis. It can appear as a slimy coating in a number of different colours. It can smother plants and may release toxins harmful to fish. It can fix nitrogen and may therefore occur in tanks with zero or very low nitrates (but possibly high levels of other nutrients, particularly phosphate). It can be removed manually quite easily, as it often forms loose sheets, but it's likely to return quickly. Improving circulation/aeration in the tank sometimes causes it to decline. It can be treated with erythromycin (200mg/10 gallons) - this may however affect the filter bacteria, so it will be necessary to check for ammonia and nitrite after dosing.
Although I dont think you can get this kind of stuff in the UK, and ive seen plenty of US sites. Anybody order prescriptions etc. wanna recommend me an easy to use cheap site? I only need 370mg of the stuff per treatment, hell it might go first treatment so obviously i wont need 1000mgs of the stuff
Cheers overseas overclock3rs!
