Hi, This tank has been setup 30 days back. For some god forsaken reason, I added ADA's Bacter 100 to the water column to take out the Cyanobacteria ( I had read somewhere that it helps in neutralising it). Now the whole tank is filled up with a reddish brown fine dust. The dust just settles on the plants and does not attach to them. A simple wave will dislodge the dust. Even a 100% water change has not helped and the dust is back the next day. Is this a diatom bloom and any suggestions on how to tackle it. The plants are getting suffocated and am worried they may die. Have done a 100% water change with Dimineralized water. Cheers, Vijay.
