Hey guys Here is my tank. It is a 110 litre tank, with an Oase Biomaster 350 and CO2 in line diffusor. It has been running for about 8 months. Over the past month, I have been losing the battle against what appears to be some form of red algae. It has attached itself to every plant, even the stems: Nothing I've attempted so far has helped - upping the light, reducing the light, upping or reducing flow or CO2. Dosing directly with carbon kills that specific area but it comes back bigger. Any suggestions will be very welcome.
