Lwalgren Posted October 28, 2020 Share Posted October 28, 2020 (edited) Does anyone know what this is? it’s like a light brown and is almost dust like. it’s all in my filters and just keeps coming back. It’s always clearer to see it on my jar and this isn’t the best picture of it but i don’t have another one yet. I also want to make sure it’s safe for my betta fish to be in there with it. Thank you Edited October 28, 2020 by Lwalgren Link to comment Share on other sites More sharing options...
