Does anything eat cyanobacteria

[Axis of Weasel]

i got this slimy black stuff growing all over my tank, on rocks, plant leaves, everything. i dont think its algae, as it doesnt fit the description of any algae

i have a couple snails in my tank as well as corys, but they dont seem too interested in the eating this gunk. are there any animals (fish or otherwise) that eats this stuff?

I've been trying to keep my tank in better condition in an attempt to get rid of the stuff -- cutting down light hours, changing water daily (25%), feeding less, etc.

if things dont improve, I might be desperate enough to try a blackout -- wrapping the sides of my tank with paper to cut all light from entering for a few days.

i wonder if scrapping it off would help? :19:

[Axis of Weasel]

well i *DID* scrape it off the rocks and decorations :hmm3grin2orange:

but it doesnt come off the plant leaves, and im worried that the growth all over the leaves is starting to hurt my plants photosynthesis ability.

plus its ugly.

couriosity, whats your tank temp?

[NickFish]

Diatoms.
Usually I sign of a new tank. It usually goes away after a while, or turns into green algae which your fish should eat. If you crank up your lighting it should turn into algae, however this will also cause a ton of algae to show up in other parts of your tank.
You could pick up some otos, they should eat diatoms. But if you wait it out, they'll likely go away. No need for a blackout, since this will not kill the diatoms and they will come right back if silicates are present.
Just wait it out, diatoms are common in new tanks and should go away soon.

note:
(If your tank is not new, and you still have diatoms, then you have a problem with your tap water, and should switch to a high quality tap water conditioner, or preferably RO water)

couriosity, whats your tank temp?

its high for some reason. i dont even have a heater but its around 80F, a little lower, maybe 78, in the mornings

maybe the light is real warm, or maybe i keep the room temp a little high.


NickFish, whats RO water? bottled water? rain water? i live in the city so even if i could get water its most likely polluted like crazy

[tropfish]

The advice given above is very good, i would follow that.

RO water is reverse osmosis water, its when all the chemicals, minerals, and impurities are stripped out of the water, leaving it at it's natural PH.

Lower the temp to around 75. That will get rid of most of it,. Then just keep anually removing it untili it goes away.
