    So guys, as requested here are a few more pictures from the tank I had in Germany.

    In August 2003 I filled this 5.500 litre reef aquarium. The whole system included filter, etc. had a volume of 7.500 litre.
    The tank was made of reinforced concrete, the glass thickness was 31 mm. The size of the front screen was 3,1 m x 1,0m. The tank size was 3,2 m x 1,2 m.
    The depth on the left side was 1,0 m and on the right 1,8 m. 2 pumps were pumping in total 48.000 litre per hour through the system.
    I used 220 kg sea salt. 3 Aqua Medic metal halides with each 1000 W and 8 blue T8 58 W tubes were used for lighting.
    I brought around 1000 kg dry reef rocks and a few hundred litre coral sand into the tank. It took me almost 3 years to finish the project. Why I left this beautiful tank behind me, is another story.
    This picture was taken in March 2004, when the tank was a half year old. The visible size of this picture is around 3,0 m x 1,0 m.

    Mixing the salt became a challenge. We set up a swimming pool in the garage, 5 metre in diameter, to mix 220 kg salt with tapwater. Tapwater in Germany is better than RO water, because it contains already 120mg calcium per litre. As a master plumber with his own business, I always could get the latest water analysis from the supplier. They check the water daily, so I had on paper, what is going to be in my tank.

    Two Aqua Medic skimmer with each two oceanrunners. Sams got the same skimmer running in his shop.

    LOL! Sorry man. I missed the 2 AquaMedic skimmers you have there. I cannot believe that I did not see that pic! WOW! Ah ok - so, you ONLY had dried out "live rock" (dry reek rock).

    No "bio rock" (man made) at all?

    Marcel - I have a few questions:
    - how did you clean the inside glass of the tank?
    - how many fish did you have?
    - how often and how much water did you change?

    I used a aqua medic glass blade and extended the handle to 1.5 metre. Standing above the tank, which means in the roof, and cleaning the glass was an acrobatic act.
    We did not have these strong magnets that time back. I had to pull all the lamps to the ceiling.

    I think I had roughly 50 fish in this tank.
    Will post some more pictures of fish and corals.
    I only had this tank for around one and a half years. After my divorce I had to empty this tank. More painful than the divorce itself. It is much easier to get rid of your wife, than of your tank.

    I did every 3 months only 10 percent water change. I always had activated carbon in use, was running the skimmers with 100mg ozone and I had a 95 litre DIY nitrate reactor running with controller. And a 95 litre DIY calcium reactor with controller.

    All the pictures were taken in the first half year, so yo can see I still had lots of unwanted algae in there. But they disappeared after a while.[​IMG]

    WOW! You had some really beautiful fish in there! I see you had some really big'ish coral pieces for a substrate....... did you not have any issues with hidden detritus in the substrate?

    It seems like they were spawning in the last pic? Amazing!

    The base of the six running metre reef was made from kenia rock. I cut every rock flat with an angle grinder, so they were laying flat on the pvc sheets. The gaps in between these rocks, I filled up with coralsand. Same like the gravel. Behind the base, I was running a closed loops with a few thousand litres per hour. The whole base was working as a filter. I actually dumped my nitrate test kit. Each test was without reading. If you have bali polyps in your tank and the tentacles getting shorter, your nitrate is building up. They were always very long.

    My favourite fish were the three heniochus, similar to the moorish idol and the sohal tang. Was a bit tricky with all these tangs.
    I think I had 5 or 6 yellow tangs, 1 purple tang, 1 naso, 4 regals, 1 sailfin and 1 sohal.
    I introduced them all at the same time, so the fight stop after the first day.
    Never ever I had a fight between my tangs again.

    Yep, every week. I always introduce mandarins after 3 weeks to my tanks. The last ones here in SA, I introduced after the second week.
    And they always spawn a few weeks later on a weekly basis.
    I had in the big tank 6 or 7 scooter blennies. Interesting guys and very fast swimmer.[​IMG]

    Good question, I actually like them and I always had plenty of them, but it wasnt that bad. After a while I had still plenty, but they never took over.
    I always kept my alkalinity around 11.
