Little creatures in filter !!
I jave just cleaned (rinsed and changed white pad) on both my Eheim 2217's.
Hundreds of little creatures came out of the top, white filter:
Very small, around 2 mm long,
Light tan color,
Wiggling and clearly alive,
They look like little ants, at first site,
Has anyone every seen this?
Have 100 gal planted tank with fish.
No problems except can't get rid of blue/green algae and little snails that came in with the plants.
