Can anyone tell me what this is please, in the first two pictures.
Ive recently rescaped my tank and this has started growing on my wood and a small amount on plants.
Also, If you can, let me know whats happening with my swords. This happened within a week. There are shrimp and snails in the tank but they haven't bothered them before.
Its a 275litre tank
I have two Fluval aquaskys, running at around 80% output for 8hrs a day
I E.I dose 35ml Macro/Micro on alternate days
And 5ml Liquid CO2 every day
