Louise white Posted December 20, 2020 Share Posted December 20, 2020 could someone help me identify what I’m dealing with here. Black growing between the sand and glass. It seems to have a cyano texture when I have tried to remove it previously. The black on the edge of the tank has looked like that for months and not changed, but where the black is in the middle has grown over a couple of weeks. I am working on balancing the tank . Just not sure if this is algae or cyano bacteria as it isn’t green ? But doesn’t look very nice at the for front of everything! @Cory Thank you 😊 Link to comment Share on other sites More sharing options...
Administrators Cory Posted December 20, 2020 Administrators Share Posted December 20, 2020 I think it's anaerobic bacteria. Link to comment Share on other sites More sharing options...
Louise white Posted December 20, 2020 Author Share Posted December 20, 2020 Thank you for replying @Cory is that something I should be concerned about ? I know from your videos about Peru you mentioned the gas release you saw there and how we shouldn’t be so so concerned with it in our aquariums. Is the bacteria build up different ? Thanks again 😊 Link to comment Share on other sites More sharing options...
Administrators Cory Posted December 20, 2020 Administrators Share Posted December 20, 2020 Should be fine, just unsightly. 1 more reason I don't like fine sand. Link to comment Share on other sites More sharing options...
