Dark aglae that my Otto's won't eat

[wes.crockett]

Hey all, I'm getting this smooth, and deep green, algae on some plants and on some substrate as well as on the motor housing of my HOB filter. I'm not sure if it's dangerous or not or if i should simply cut it out of the plants.

I should also say, I haven't had nearly any plant growth in the tank in the 3 months that it's been live... plants are still green, just not growing. I'll add a photo of them tomorrow (kid is asleep in the room with the tank.)

Any ideas?

Looks like cyanobacteria honestly.

Yup. I looked it up and that seems to be exactly what it is... Looks like I need to do a deep clean and reduce light.

I use Fritz Maracyn (antibiotic medication) to get rid of blue-green algae. I have even dosed it at half the recommended dose and still got good results (1 packet in a 20 gallon aquarium). It doesn’t go away immediately, but you’ll see pieces flake off and then gradually disappear over the course of a couple days. Then you just do a big water change to remove the antibiotics and boom, no more Cyanobacteria.

I have never used that one. Sorry, I should have been more specific. You are looking for the active ingredient Erythromycin. I buy mine from Aquarium Co-Op. https://www.aquariumcoop.com/products/mardel-maracyn

If you cannot find the Maracyn brand one, you can also get the API Erythromycin. https://www.petsmart.com/fish/food-and-care/disease-treatment/api-e.m.-erythromycin-fish-bacterial-infection-treatment-5113625.html

I saw the Aquarium Coop one this morning and ordered it. Thanks so much, again.

 best of luck.  Steenfott aquatics has a video on it, he had a pretty bad outbreak in one of his tanks. Manual removal, siphon, treatment, etc.
