    RW15's placement?

    Hi I wonder if anyone can help with ideas. My tank is 1500x500x448. Have 28kg of LR in and 20kg washed play sand as substrate. My problem is that after adding the two RW 15's the create massive barespots in the tank bottom and shifts that sand all over the tank. Is there any placement I can do...
