I removed the plywood shelf and will be mounting my main hardware to it. I will obviously be using Vortech powerheads to move water around the tank. I have two now and seriously considering a third powerhead for the right side of the tank. The acrylic structure you see in the pic was designed and built to hold my Profilux controller and dosing units. The space in between the battery backup unit and shelf will fit my Profilux wave controller perfectly. Not 100% sure I will mount it there yet? ...
