Swedish fish - behind the scenes rebuilding a public aquarium

Sallstrom · Feb 19, 2020

Morning in the coral spawning experiment.

Added five urchins yesterday, plus a filefish. And one more test coral, an Acropora efflorescens.
Now I need to catch some Ctenochaetus tangs and a rabbitfish and move over to this tank, to avoid a too large algae party

After a month or more with just old water and rocks, the nutrient levels are a bit high at the moment. But since I feel the algae refugium is quite large I think that will sort it self out soon. Together with a small dose of ethanol every day.

A picture of the construction area in front of the museum building.

And the museum building and the tower from the other side.

Is the aqua blue excavator digging for the aquarium exhibits?

The blue one is digging for the cold water part, and the yellow one for the warm and tropical part. Of course ;Happy

Although it's missing razor wire and has too many windows, from this angle, this pic reminds me of a prison.

Haha! Yes, I can see that too. Specially on a grey day like the one on the picture

Perhaps I should look a bit closer at my photos before posting! I just though “hey, that’s a new angle”

Found a hitchhiker in the coral spawning tank

Let’s dose!!

Coral spawning experiment is developing.

I kind of overdosed Chaetomorpha algae and light in the refugium. Phosphate went from 0,25 ppm to not detectable on our Hanna checker. In three days. Nitrate from 8 ppm to non too

So now the light hours are less for the macro algae and we’re dosing some nutrients. I guess things will change later on when we have more corals in the system and we’ve started adding coral food.

Some cute green algae are growing in the display

I did the shelf for the doser 2 - not for your bottles

. But it looks very good - let it be

I find another place.

I can see that the photosynthesis had started in the DT too

Sincerely Lasse

Oops..

And I haven’t even started setting up the food that will be dosed!

Photosynthesis, must be all the yellow light

Lasse · Feb 26, 2020

It works out well - keep it that way. I´m like life - I will find my way

to complicate everything with a doser Maxi

Am I the only one thinking this?

I had to do a google search before I realized it was a Pink Floyd album cover!!

More equipment to the experiment setup for sexual reproduction of stony corals! Now we can simulate storms too!

And a good looking Norwegian anemone, for the cold water aquarists

Sallstrom · Feb 28, 2020

The hole is getting deeper. In a couple of months the will start doing walls and floors!

Meanwhile in the temporary Aquarium..

And another beautiful cold water anemone.

Have you looked into the Rainbow Bottom Anemone as something to add to your cold water tanks?

Finally something decent to look at! Over here in mighty Skövde, strong hometown of mister Lasse we have a proper winter with snow now.

Lasse · Feb 28, 2020

I have some snow on my backyard but if I look down in the valley - no snow at all. But it will been gone tomorrow. More rain coming in.

Next part of the series “Building a coral spawning system”. The main series “Building a new public Aquarium” will continue when there’s more interesting content than digging

This week I’m trying to tune in the nutrients. And of course there’re algae and other stuff growing since it’s a new system and the lights are running as normal days.
I wanted a large refugium with macro algae and that we have. But since we haven’t started that heavy feeding yet, the nutrients decreased down to near zero. So now we’re adding a lot of KNO3 and KH2PO4 to get readings on our tests. Feeding with coral food will increase this week.
If I’m right the Cyanobacteria will go away in a week or so. We’ll see if I’m right..

This time setting up a new system and a Profilux GHL control computer, I wanted to learn more. @Lasse is our GHL wizard and have installed everything this time as well, but now I’m trying to be a bit useful too when it comes to programming. So here’s my attempt to coral feeding programming. We’ll see if it gets Lasse approved..

Feeding 09 and 15 everyday(40 minutes):
Return pumps goes down to lowest flow.
One skimmer pump turns off.
Dosing pumps dose food.
This is for the food to stay in the tank longer.

After a feeding(45 minutes after start)
Skimmer pumps on.
Return pumps back on normal
Stream pumps in tank goes on thunderstorm - 90% instead of 20-50%

Using the functions Thunderstorm and one Feedpause, plus individual dosing for the dosing pumps.

All we have to do is fill the coral food containers every morning.

Added this NPS to hopefully see some feeding respons.

Still a bit left before the experiment starts. Cover everything from outer light. Program moon, daylight and light intensity over the year. And some more stuff
