I've got a couple questions regarding equipment placement in my 12G AGA. I searched through some threads but most surrounding equipment placement dealt with AIO chambers.

My plan is for a simple set up so I only have to worry about a heater and a powerhead (with the possibility of adding another if need be).

First - the heater. I've got a submersible 50W Jager and I want it as hidden as possible. as I search through the gallery most people seem to have them hidden in sumps or chambers in AOIs. I couldn't see any in AGAs so people must be doing something right! Will down at the bottom behind rock work? I haven't got my tank set up yet so pics aren't really a possibility. I guess I can probably play around with the set up when I've got everything in but I'd appreciate some tips here.

Next - powerhead. Its my understanding that this depends highly on aquascape and desired coral. As far as I know this is something I'll definitely have to play with to ensure my livestock is happy. If I do my best to keep random turbulent flow with some low flow areas for some desired types of coral I think I should be alright.

Let me know what you think. Thanks in advance!
