Hi Guys,
After 1 day of a 80L water change (my tank is 180L), I have seen some dusty of algae in my tank, I thought , "the fish and snails will get rid of it". (I have checked ammonia, nitrite, nitrate, all okay) I reckon it was an spike of phosphate (but how come?)

Few days later it looks like a melted plastic.
(I have taken a picture of a Christmas, moss and a moss ball and the substrate.)

Anyone would be able to explain to me What is that and how to get rid of it?

Thanks in advance guys.

Looks like cyanobacteria (blue green algae) to me...
 
... If it is its very difficult to get rid of in my experience. You've got to manually remove it if you can, it photosynthesises so if your lights are on longer than necessary or the tank's near a window try to lessen the exposure. It likes slow moving water so speed up the current if you can and don't over feed the tank
 
Yep blue green algae (Cyanobacter bacteria). It comes in a range of colours from dark blue, green, red, pink, brown, black and purple.

It loves low oxygen levels, poor water movement, dry food and red light.

Increase aeration/ water movement in the tank.
Reduce the amount of dry food going in.
If you have old fluorescent lights on the tank, replace the globes & started with new 6500K globes.
Do a 75% water change and gravel clean every day for a couple of weeks to try and physically remove it from the tank.
