Very nice, I have a 125g planted tank too. Do you have anymore pics from behind the scenes, that include the lighting etc?
you got it.
the green tape is holding black foam core board up. it's starting to droop, so a more permanent solution is being considered.
the light is a 6' led fixture from buildmyled.com
the sump is a ~40g display tank from a petco that came predrilled. though, i am only using one hole. I need to redo the baffles i put in, as 1/4" thick acrylic deflects WAY more than i thought it would. it's useless! and peeled off away from the silicone. I have 1/2" thick from a friend (for freeee) that is way thicker than I need, but it won't budge. in the center you see plants, i'll eventually have that lit. it has flora-max in there now.
sadly, i have to stop the tank and redo at least two of the baffles, but that requires draining it and getting out all the substrate. I may work on that this weekend... or i'll just let it go as is and see how things end up.
the plywood to the right, of the bottom picture, will have a shelf eventually to hold the LED driver and anything else i need to put there.
still need to move the CO2 system from my 20g to this along with getting a new power strip w/ timer.
eventually a raspberry pi will make it's way into the mix and control timing, heaters on/off, reporting, feeding, dosing ferts.
