What do you use as a filter intake guard? How much trouble are small sponges?
I didn't think I needed a guard, but apparently I have a dumb batch of ramshorns as this was the second morning in a row that I found one with it's shell stuck to the intake and it's body sucked up into the tube.
I have an idea of using some plastic craft mesh and heat shrink tubing to make one, but am wondering if I'll be able to find mesh with openings as small as I want them to be. SS costs too much by the time I pay for shipping.
