Helsinki Low Iron Reef - 910 liters

The Cardinal

Swede living in Finland
Greetings from Helsinki Finland :wavehand:!

BACKGROUND:

After living as a kid in Miami in 1985-1986 I was amazed with the coral reefs at Pennekamp and the tropical environment so different from my earlier childhood in Sweden. I dreamt that one day it would be possible to have corals and marine fish in an aquarium; my own slice of the tropical ocean when the winter storms raged outside my window to lighten up the darkness of the North.

In 2004 I stumbled upon Reefcentral and saw the TOTM and was thrilled to see the amazing results that technology and the knowledge could produce.


MY FORMER REEF TANKS:

In 2005 I therefore started my first reef; a 375L reef without a sump converted from my fresh water aquarium:

I also started a smaller 275L cube aquarium in 2008 where I kept seahorses and my captive bred Banggai Cardinals:

In 2009 I had to stop with the hobby due to changes in my family situation.
 
MY CURRENT 910L/240G PROJECT

I knew I would get back to the hobby when I had a chance so I saved much of the equipment from my previous reefs. About a year ago I started planning the new aquarium and as most people I wanted to go bigger :spin3:.

PHILOSOPHY:

The display would be a central part of our apartment and fit in aesthetically with the rest of the interior. I wanted to make the aquarium as safe and quiet as possible and at the same time hide all technique from view. The biological aspects would be the primary focus so I wanted to incorporate a refuge as well that would be viewable from the side and add interest/filtration and biological variety to the display.

THE PLAN ON PAPER:

Central placement in apartment:

The inlet hole to the refuge is now close to the bottom and not the top as shown below:

The stand (some modifications were made to the design)

SUMPLESS:

I again choose to go without a sump in order to use less pumps/heat/ noise and money to transfer the water vertically and also lessen the complexity and the risk of leaks and possible fire. I had a flood due to an external skimmer in my old tank so I decided that the skimmer must also be placed inside the aquarium to further minimise the risks. I simply chose a larger aquarium than I had originally planned.

REEF CERAMICS:

In order to hide and remove all equipment from the main display I hid the technique compartment with a wall of reef ceramics customized from Germany:

REFUGE:

To the right of the technique compartment I made a space for the refuge measuring 12cm or ca 55L in total. The refuge is viewable from the right side and will function as a biological filtration using live rock, sand and chaetomorpha. It will also provide live food from the micro fauna produced here. The refuge is fed with a pump based in the technique compartment and the water exits through gravity back into the display. It will be a fun challenge to make the refuge an interesting part of the viewing experience and not have it hidden from view.
 
UNDER CONSTRUCTION!

With help from a good friend and drawings from RC we built the stand.

There is a sturdy wooden sheet attached to the back side of the stand that is not clear from the photo below.

AQUARIUM SAFELY IN PLACE!

After some heavy lifting three work colleagues helped me to bring the aquarium in place at the end of August. The work carried out by Eheim/MP is very good and polished. The low iron does make a big difference and worth the extra cost IMO.

AQUASCAPE:

I ordered 60kg base rock and 10kg live rock from Germany. The base rock consisted of some really nice large light weight rocks which was easy to work with.

Upon arrival:

AQUASCAPE IN PLACE:

Left side. On the left side I have tried to resemble the vertical islands seen outside Thailand for example and also try to add visual depth by placing a smaller rock in the foreground (the plan is for this rock to be covered in ricordea later for the size to remain small).:

Middle. For the middle part I have tried to make a spiral formation that moves in a circular and upward movement. This is a bit hard to see in the photos but I think it will look good with the right corals/planning/trimming. :

Right side. The wall of reef ceramics creates a dramatic reef wall going up to the surface of the tank. From the right side I have then made the other parts progressively smaller towards the left side and I will have this in mind when the corals grow.

To add interest and improve circulation and hiding spots for the inhabitants I have chiseled out several kg of rock to make caves that run through the rocks. This also adds visual depth to the scene and a three dimensional feel to it. I have also added shelves to some of the rocks but these will likely be removed later when the corals have grown to avoid a cramped impression. I will try to keep the sand free of corals to keep the open spaces ... open :D.

The lighting in these photos are only from the T5 in the back so apologies if they are a bit dark.
 
Thank you very much guys, appreciate the comments and glad you like it! Many of your creations, not least yours Ching, have been a source of great inspiration and admiration for years :wave:

Hi Adddo, nice to see you here as well :)! I believe you have seen the pictures in saltvattensguiden. My user name there is Clownen. I hope I am not doing something wrong when uploading the photos??


FIRST CORALS & CLAM ORDERED:

After around 7 weeks with water in the system and stable water parameters I have now added the first LPS corals and clam Tridacna Derasa:

Hi. It looks like you are off to a great start. Just a couple of questions:

Your initial drawings show the space above the tank to be enclosed. Will you continue with this plan, or will you just leave it open?

I can't help but notice there are no fish. Usually people have some fish to create a bio-load and get the bacterial filter going. Will you be adding fish?

Thx,

Dave.M
 
Thank you Bello and Dave!

Dave: I am still building the top of the tank according to the drawing and it will be more or less finished next week. I had enough die off from the live rock not to use fish and I have been feeding the worms and micro-fauna that already live in the tank/refuge. I have collected sand from three sources to add bacterial variety. The first fishes will come next Wednesday and will probably appreciate the cycled tank :).
