This is an amazing build!
Best I've seen in quite some time! Congrat., and do keep up the great work your doing!!!!!
I disagree/agree with NYfireman concerning the algea. I would wait, and see how it grows! You may, or may not like it.
I've seen some tanks with that type of algea growing in it, and they look very nice/natural. Of course I'm sure they are trimmed in order to keep it in check.
I'm going to repeat myself here; you will more then likely hate the house thermostat being so close to the tank. The temp given off by your lights (especially VHO & MH) are going to make your thermostat get false readings making for a chilly home.;-)
Well I have to say I have thought about this problem and I will be relocating the thermostat by next winter. This winter is almost over and we will not have the lights we need for the tank by the end of the winter so I have all summer to move it. We are doing a kitchen remodel in a short time and I will move it then. This is the only place I was able to put the tank so I will have to deal with it.
By the way, you are certainly making it very hard for me to shut my tanks down.
