Thanks.
I wanted to make sure it has enough cover, yet enough room to stretch its fins. I also used the wood to create eddies, direct flow, calm spots and light flow spots. That way it can pic what it likes. I might add some more large rocks to the right corner below the powerhead(800gph). I also have a hob ac50? Or ac70?(can't recall) pointing into that corner. That way there are different angles to the current to get more swirling and also directional flow along the front panel. Once it can go into the 180gal it will have more directional flow, with a couple eddies. So I want it be used to that so it don't stress once it gets moved.
