today I have noticed fluffy white stuff like cotton candy growing on my black gravel,it more around the edge of the gravel near the deco wood, just been planted in low tec. any ideas?
It'll be a fungus of some sort; usually harmless; just syphon it out, but do check it's not rotten food; that would be sign you need to cut back on the feeding a bit.
How often do you feed?
