Hi,
today I added a Salarias fasciatus (Jewelled blenny) and a dozen small red hermits to the frag-tank. That should do against the algae.
jnarove,
The Vortechs look really interesting. They are known in Germany, but the usual (online-)shops do not have them

. Hmm, I'll start with the mentioned setup, maybe the flow from the return-pump is enough that way.
Nevertheless, I'll try to get that Vortech somewhere here.
laomedon,
it's a strange feeling, filling such a tank for the first time... you'll surely discover that ;-).
Sure I like to answer your questions, even more if you like ;-)...
1 - I don't like to see too big fishes in the tank. My goal was to build a system, where you have the impression of looking into a bigger part of the reef than in the "normal" sizerange.
Having larger coral and also many large fishes would IMHO result in the impression of looking into a "standard" sized system but at another scale. (4:1 instead of 1:1 or something like that).
(Hopefully I was able to describe what I mean).
So having a Naso lituratus or a Acanthurus sohal or something in that sizerange was never an option.
As the biggest ones I've chosen the Siganus magnificus, Acanthurus leucosternon, Acanthurus pyroferus.
2 - oops, I have to confess, that was misunderstandable ;-)... I cought the goby and replaced it with the other two... The Kole is still in there. Catching the goby wasn't difficult, because the Kole hold it in an upper corner.
Catching the Kole, I would try a mirror-trap, which is a acrylic box with small holes in it and a door which can be closed (dropped) by releasing a string. In this trap there would be a mirror at the side opposite the door.
3/4 - Yes, I am able to reach all places (with a small ladder), but working near the seafloor means wearing a mask if you want to see what you do ;-). A large gripper is used quite often.
That was also the reason why I did it in that size. I think this size is (for me) the largest possible size to be easily maintainable by myself without any help.
The length was defined by the size of the tech-room. Bigger wouldn't have looked harmonic from the livingroom. Hmm, and I don't like the look of a tank relatively shallow and very very long.
5 - Using only T5 (willing to loose the beauty wave-ripples HQI produces) would certainly mean using less power.
But I want to keep light-hungry SPS also on the bottom of the tank and think thats not possible with only T5 at 85cm height of tank.
Using the smallest available T5-lamps and covering the whole available surface area with them provides still not enough light for my needs.
HQI has a higher "lightdensity" i.e. more watts on the same surface area.
Therefore a combination of 400watts HQI and T5 was chosen.
The others, thanks for your kind words,
Ralf
