hello all
This one is new form me , it shows up on the glass like a foil fim ,
It's on the sand it basically covers the sand , and it is hard to remove, even by vacuuming the sand
Looks like cyano. Yes, knowledge concerning Cyano is reef basics, but sometimes the simple answer is the right one. Be mindful if your aquarium does or does not have a good bacterial balance; this is something often seen in many new aquariums. Brightwell Aquatics MB7 can help create that bacterial balance and remove that new tank syndrome.
