I also recently visited this tank and have to agree it is a stunner.
Transparent to anyone entering the abode is any semblance of work. To the uninitiated it looks like fish in a bowl - and beautiful fish at that.
All the real hard work lies beneath where a large sump, big chiller, huge skimmer, and a calcium reactor that has to be seen to believed does the work. Well not quite all the work. There is water flow to be compared with a tidal wave at work in the main tank.
What I particularly enjoyed was the employment of caulerpa in the refugium. Nothing against the zeovites out there but just to show that you can achieve great success either way with nutrient dissipation.
I took loads of pics for myself but none, and I guess this is just something 2D cameras can't do, really show the depth of the system. From the front the tank is wide - 2M or so; but the depth is equally impressive at another 1M giving so much extra room demanded of the large fish that adorn the display.
Yes - Mr Puttputt is truly an advocate of SPS and specimens outreach (literally) the tank. The colours are vibrant and the water is crystal clear.
From a personal perspective I was intrigued to see that all this was achieved with the use of NSW. I don’t want to start the debate again – it’s long harangued now, but it does confirm to me that with proper care you can sustain life with either ASW or NSW.
What is still quite amazing to me is the timeframe that has elapsed to get the tank into this form. As a marine aquarist of nearly 20 years I would not have thought it possible to get a system running quite so well in such a short period of time as this – some 10 months to date since set up.
I was privileged to be allowed to see this for myself first hand. Hope you guys get the chance too.
