I think I have a tough one here.... I have a 75 gallon Hex (6 even sides) that I want to plant, and do right. It is 25 across (from each flat side to the opposite) and 30" high. It sits on a rock "ledge" on my fireplace. A set of stairs (log home) go behind the tank. So basically, you can walk around all but one side of the tank. The side you cant walk around is the stone chimney. I can stand on the rock ledge and get over the tank to plant it and take care of it. I have a Eheim canister w/built in heater. I ordered a CO2 system and a tall driftwood and some plants from Florida Driftwood. As far as lighting goes, the type of tank came with a strip, and I have added another thing to hold a 2nd light bulb. I don't think the wattage is high enough. 30 watts total. Can anyone recommend a light bulb to go in this fixture that would be better? Any recommendations on planting arrangements, keeping in mind that you can walk around this tank? Thanks for your help!
