Many bags of pool sand later, pretty much ready for fish have my spare return pump in the sump now with some old heaters warming the water. Also added two tunez wave makers tank should roughly have 7500gph turn over after head loss on the pumps. Relocating the fish in 48hours along with media and return pump going to be a hectic day. Moving house has taken priority over finishing the tank off. Still want to make sure all the cable management is tidy new air manifold and clean piping for the air pump and then insulated box and cabinet will come together.
