it is! LolLol think this is the 4th post this week on this stuff, it's just a type of bacteria realeased from the wood, it's quite common, sick it from the wood with a syphon, hoover up any other bits and after a couple of times it should go away. My 100litre has like 10 bits of wood in and I got it a few times, nothing to worry about.
Haha sorry i should really forum search before asking questions.
Thankyou anyway![]()
