The fake wood decoration in my tank seems to be growing, some sort of algae and it’s spread spreading to my sponge and changing the colour of the wood the two first pictures are before and the last two is it currently i’m wondering if it’s just normal algae or if I should be worried about I’m dealing with biofilm problems because of new plants adjusting so just ignore that but the neon green also worries me cause that’s def not algae I’m wondering if maybe it’s leaching paint into the water? Water parameters are perfect so I’m just not sure what’s going on any advice would be amazing
