Aquarium Advice FINatic
Hey all. This is starting to grow on my sand.... what is it? Is it caused by too little circulation?
warvillian said:I believe it to be a diatom bloom. How old is your tank?
AquaRick said:Yup looks like diatoms. It's caused by excess silicates in your tank. However, if it's on your sand and not just your rock, it's due to circulation issues on your sand. It will go away on it's own as the silicates in your tank are consumed. They usually show up in a new tank and/or a new light set up etc.
AquaRick said:How big is your tank? Yeah i've had my tank setup for a few months without any lights (just ambient light from the windows in the room etc) and never had any outbreaks. Finally finished my canopy and strung up the 8bulb t5s and got diatoms for about 3 days on all my rock.
