I have, in the past, had problems with my mj mod sucking up anemones that like to roam.
I have a 110g that is 72 x 18 x 18 approx.
Are there sponge covers that could work? I tried one sponge and it didn't allow enough water flow.
Any suggestions?
Some coarse sponge covers work , or you can just buy some filter material that comes in sheets or rolls. Cut to size and use rubber bands to hold the material to the power head intake .
