Hi bros,
Currently running a 522 with OHF housing 1 aro & 3 TFB.
Just added another tier and was wondering would it be best to add Bact House in the second tier. or maybe last tier?
First tier consists of wool+jap mat.
Second tier: None atm.
Third tier consists of CR.
Reason is : Gonna house a pair of rays soon.

Any help/advice is greatly appreciated.
