Hi
I was wondering if anyone has these strange columns in their tank.
Towers are built out of sand/crushed coral and a white filament comes out of the top of the column. I have had several of these in my tank for over a year but cannot find out anything about them. They do not appear to be having any detrimental effect to the tank but I am just curious as to what they are.
