I had to turn off the air pump to get the shot I did. All tanks/tubs/containers have a airstone for water movement. A few have filters/sponges. Not all are lit as I need more lights. I still have 2 more tanks to move over to this location. My 20 gallon shrimp farm and a ten full of endlers. Not in the pic is a 75 and a 10 I set-up as a micro farm. So I guess I have MTS real bad:hihi:is every "tank" lit? i might just be blind but i don't see any lighting sources for some of them. but using the plastic tubs and organizers for this purpose seems like a good cost cutting approach. how are they filtered, if at all?
