Yes. Move that one that's up in the air to the other side of the one that's down. Then remove the other one completely, or at least move it closer and lower it some. 1" from the bottom and 1" away should be good.
So, trying to explain this better- first partition sits on tank bottom, second is moved to 1" off the bottom, and 1" away from 1st, and 3rd either is not used, or can be sitting 1" away from that one, and on the bottom.
