Pet Forum / Aquaria / Goldfish / September 2005Black Algae ?
I have a problem with a black algae in my tank. Its 180 lite tank with 10 small to medium sized goldfish... Using a eheim pro filter. I change the water ...top up 1/4 to 1/3 every two to four weeks. I have a number of varieties of cold water plants. I have noticed originally that the black algae was minimal and was restricted to certain plants...smothering the small leaves. Now its got worse and the black algae is on all the plants and the algae has progressed to being a furry black algae. Does anyone know what it is and how to treat it. I have tried to remove the plants and clean them individually....to no avail. On closer inspection to the gravel its growing there too. Suggestions ?

Anyway, go to www.algone.com and try their product. I believe it is only available on line and through them directly. Also, try PURIGEN from SEACHEM to remove pollutants from the water. The pouch is expensive, but you will see a difference right away. You can get Purigen through PetSmart. Lots of on-line stores also sell it. Good luck. n > Sounds like your tank is overstocked. > [quoted text clipped - 6 lines] > pouch is expensive, but you will see a difference right away. You can > get Purigen through PetSmart. Lots of on-line stores also sell it. Black algae is like herpes. Once you get it, it seems you have it for life. It's very persistent, and I've read that algae treatment products can often make black algae worse by only killing off the competing strains of algae that help to limit it. If Algone doesn't do the trick, then you might want to try taking out your plants and gravel and pouring hydrogen peroxide over the affected areas. That will definitely kill off the algae, though it's a radical treatment that might hurt the plants somewhat as well, but you may have little choice. - Logic316 "A democracy is when three wolves and one sheep vote on what to have for dinner." Read this article: http://www.thekrib.com/Plants/Algae/red-algae.html Although that algae can appear black, it's really considered a red algae. Unless you are willing to provide for live plants, and it's not an insignificant effort, then plastic may be the way to go. TW |
