Swedish fish - behind the scenes rebuilding a public aquarium

[Lasse]

My wife had never left the US/Canada area so she likes to see what life is like outside of the bigger cities and tourist traps. She even likes the idea of local food until she has to eat it. ;Wideyed

Here in Gotheburg you can get all of the typical swedish food like pizza, chinese, japanese, thai, falafel, gyros, kebab - you name it Probably Swedes have embraced more foreign food than other nationalities. But if you come in the fall - we have to make a "kräftskiva" for you. Swedish crayfish party

If there is a good Italian restaraunt (And by good, I mean fake Italian with american style pizza and heavy red pasta sauce) then Gothenburg may become her favorite city in Europe!
I will admit, even I am not brave enough for the Lutefisk again. Once was enough... or too much. ;Yuck

 

[Lasse]

Here we have Italian resturants that make you feel being in Italy. A lot of them. Did you not manage Lutfisk - that´s nothing compared with surströmming

Umm... Me. I'm more of a southern BBQ kinda guy than fermented bait or soap soaked fish.

When it come to BBQ, in the States we don't mess around

Lolol. Wow that looks amazing by the way.

First something for all the foodies in this thread Today we had smörgåstårta for lunch(a colleague celebrated and brought it to work). That's something Swedish you should try!

Then some more light fixtures. Now we have a Hydra tank. Reusing fixtures from our propagation tanks. Took me two minutes to programme all five. That I like

Trying out new stuff. I have a plan..

Those frags on pipes looks a bit like the tower next to the museum

That was not my plan, but kind of fun

I'm at a loss... what are the long posts for? My initial vision was a handle to use them in a children's parade from a coral "touch tank"!

Hehe. No

My plan is:
1. Coral grow and get to a medium size colony.
2. We buy a waterproof drill.
3. A diver drills holes in the rocks.
4. The next diver insert the pvc pipe with the coral! ;Shamefullyembarrased

Plus our frag plugs posts are a bit small so they move around on the egg crates, a longer base and they won't fall over! And we can use more of the light in the propagation tanks having corals on different heights (just my theory..).

Here's the status on the new propagation systems!

Acrylic tanks ~4000L
Corals and lights in four out of six tanks now.
Mostly SPS + Euphyllia
NO3 quite steady at ~ 1ppm.
PO4 low(Hanna LR says 0).
Adding some KH2PO4 now and then to make sure the phosphate is not depleted.
There're actually a lot of fish in the systems now so I think we will see some more nutrients in the water soon. Still haven't added a macro algae refugium yet. I'm afraid it'll use up the few nutrients there are. But it will be a refugium connected sooner or later. Might try to use the sunlight and put it in one of the windows. We'll see.

White plastic tanks
Two tanks running, volume ~ 4000L in total.
Lights up over one tank, but started to add lights to the other one today.
Mixed reef, lots of soft corals at the moment but will be a lot of SPS as well. We're moving in Seriatopora hystrix now(and we've got a lot).
NO3 at 5 ppm and PO4 at 0,04 ppm(Salifert and Hanna LR).
I'm a bit surprised the nutrients went up here. We used more newly mixed saltwater to this system and there are not that many fish yet.
It might be because most of the bottom layers of rocks in our old soft coral tank ended up in this system, with some 15+ years old sediment.
Anyway, the levels are great now so I'm not worried. Just curious


So far the move to the new tanks have been successfull. But I'm aware we're moving fast so I keep a close eye on the parameters and the health of the fish and invertebrates.
We can do large water changes if we need, using water from our large reef tanks that's still running.

There are some algae growing but having lots of urchins (we've borrow urchins from the shark tank and the 10000L reef) and at least one tang or rabbitfish in each tank I think the situation is under control.

This week the alkalinity has started to decrease. At this point we're using Triton Core7 as supplement for KH, Ca, Mg etc. Might add calcium reactors later, but at the moment the good ones are still running in the old systems.
So it's a lot of KH testing and dosing adjustments to do now. KH is around 6-7 dKH. I aim for 7 dKH.

That was a lot of text But it's fun when things are moving forward so I guess I'm a bit excited!

Happy Easter!

Here's a picture/retweet on the lower plastic tank. A bit more accurate colours than in my pictures from LED tanks..

The post is from my friend Stefan. He's working for the LED company Heliospectra that we do some research together with. That's why he's so happy about the lights

The lights are great, but ~50% of the diods are red. So we're only using half its capacity. If they do design a version with a spectrum for corals, these fixtures would be fantastic though.

Happy Easter! Well, almost.

I'm curious as to why you use the Core7 instead of buying the individual chemicals and mixing them yourself? I would have thought this was cost prohibitive on the scale you must need to add them. Or are the Core7 chemicals much cheaper for you than we can get them in the states?

Triton Lab is our only real sponsor/donator. So all their products and tests are free for us(at the moment). And I like test Core7 a bit more to see how it goes.
With the old tanks we've runned calcium reactors plus Triton additives when needed for years. I don't like to change things that are working. The calcium reactors were there before Triton came along and they have worked well.
We will probably run a combination of Core7 and reactors later on. We've got a lot of home grown coral skeleton to use up

So when it comes to Triton lab I'm bias But if I wasn't happy with their products I wouldn't use them. The animals wellbeing comes first. Fortunately I haven't been disappointed, I think they are a good company and I'm very happy for all help they've given us!

Playing around with Snapseed. Need to learn how to get the right colours under LEDs.
Here are some corals.

Acropora hyacinthus

A mix of Euphyllia

A month and three days progress in the Temporary Aquarium.

And a couple more pictures from today

Might look a bit chaotic, but it's actually in pretty good order for being us

Here's @Lasse 's GHL- and coffee cup stand

Here's @Lasse 's GHL- and coffee cup stand. Movable and easy access from both front and back side. But we need to paint it white so it fits in with the rest of the stands..

Very nice, alot work. Thanks for sharing
