Hi all,
I purchased the blue sponge that is shown here (this a crappy camera phone shot before I bought it as my lights are off)
and this is another sponge that I am thinking of getting... (I think it is the same kind just another color)
What care is needed, what conditions are best etc...any problems having two? (My blue one is in lower light and decent, but not strong flow and seems to be doing fine)
Lastly, anyone know what these are called?
