Very good mate, that's a serious set up! Done really smart and professionally.
If I can ask how much did this build ran you?
I'm looking at an upgrade from my 8x3 and considering whether something like this is more worthwhile than a pond with a window lol
That depends a lot of where you put it, if its in your house its far easier,
my garage had no drains, no water and no electric, It also needed fully insulating and boarding. So some of the largest bills were for simply getting it ready before I had even started building the tanks. Also I wouldn't go so overkill on the heating system, its turned off 90% of the time, the room generates enough heat from the pumps to maintain the temp at 30 all year round, I attribute that down to the insulation.
the biggest bill is glass, because of the dimensions it was 19mm and £500 a piece I believe fitted (I didn't have the suction tools to fit glass that size), I cant stress enough that this varies greatly, I fitting the pond window 6 months later which is only a third of the size at 19mm and that cost the same price! you can also save money by altering your dimensions, if I reduced the height slightly I could have had thinner glass and saved considerably, I was big headed though and wanted the biggest I could possibly fit even if it meant saving for longer.
the filbre glass is probably second most expensive but again its the best I have seen and required no sanding afterward, which is something I know other people with ponds have had to do before filling.
