can you drill the back or are you comfortable doing so? if you do let me know how it turns out.
your heat has to be comming from all the powerheads. remember you dont have alot of water volume here.
1 for the return
2 mj 1200 for the flow
1 for the skimmer..
IMO overkill!
figure out how to bump the flow up on your return. use lockline to spread out flow. take out the extra MJ's, and Ill bet ya your temp will come down some.
add a wood airstone to your skimmer and it will work like you never wanted it too.
