Attached is a very crappy drawing of my "sump" in my All In One Ecoexotic 25g tank.
For some reason the middle chamber gets flooded sometimes. water collects over the blue filter pad. As soon as i take off the filter pad air bubbles come up and the water drains through no problem. Then it wont get blocked up for a few days.
I thought there might be a blockage with the rocks below - however i moved them around and there is no blockage. and once i lift the filter pad water flows through fine.
The blue filter pad sits on a plastic base. the plastic base has holes in it.
Is it something to do with air getting to the middle chamber? that would explain the air bubbles coming up when i remove the blue filter pad.
any advice would help.
thanks
