Here’s the coral I used a saw to frag a while back. It looks great I think! Funny it has grown onto the rock under it, where there’s no light.
And a couple of pictures from other temporary tanks.
I looked through 20 pages of this thread to find a post with pictures from my saw session, but couldn’t find it. This thread is too long now..
No, that experiment with KCl is on ice.
Our plan was to set up a system with only corals and increase the potassium level where we could keep the corals for a longer period. At least longer than it takes for the egg of the flatworms to hatch.
What concentration and what KCl product do you use? And how long dips?
What am I looking at here?Just caught a copperband butterfly and a rabbitfish in my homemade trap. In one go! Without breaking any corals! Feeling very satisfied
Needed them in the experiment tank.
Here’s the trap. Very advanced ..This time I’m hoping to get a Ctenochaetus tang
So the picture didn't explain it all?
Ah ha! I thought so but I wanted to be sure I understood the home made contraption! Very cool!So the picture didn't explain it all?
It some kind of acrylic box with one open side. Which I modified with egg crate over half of the opening and a lace. When I pull the lace the box rises so the opening gets over the surface while the egg crate part is under the surface, trapping the fish inside.
I tried to have it with the opening facing upwards. That wasn't good. Too scary for the fish to enter from the top. So I turned it a bit, so it would be easier for the fish to swim inside. It worked
Have a look at this. I have been using this. From the ingredients listed it appears to be KCI. Try the dosage listed in the product.Our plan was to set up a system with only corals and increase the potassium level where we could keep the corals for a longer period.

We did set up a system and raised the potassium level, but we didn't get the system to work good enough overall. So we put that experiment on ice
I had to look through my notes to remember the results on the short dips we tried. We had some coral die off when we tested dips with KCl. It was a bit too potent according to my notes

Thanks! I've heard good thing about that product before. It's on my list. Will try it soon.Have a look at this. I have been using this. From the ingredients listed it appears to be KCI. Try the dosage listed in the product.

where did you get all of those low boys?Hi
I thought I might start a new thread writing about our journey building a new public aquarium. I work as a marine biologist and aquarist at The Maritime Museum & Aquarium in Gothenburg, Sweden. I think I've been here about a decade now. Time flies
The Aquarium was founded in 1923, and moved into the museum 1933 when the museum building was completed. Over the years the Aquarium has housed lots of different animals, from Galapagos turtles to monkeys. But since 2001 there's only aquariums. And since 2009 only marine tanks and animals.
We are a non profit museum, funded mostly by the the city of Gothenburg and a foundation. But we also need to get some sponsors, so if you....
Here a picture just to lighten up amongst all this text..
Here comes some info on the Aquarium today. We got about 20 tanks running in the exhibition, from 50L to 25 000L. The total water volume now is around 50 000L. We've focused on tropical reef habitats and Swedish temperate coastal waters.
We are five people working full time in the Aquarium, but mostly three of us are responsible for the aquariums.
And another picture to get people to read the rest of this long post..
I've written some about our 10 000L reef tank in my build thread in my profile, so there you can find a lot of pictures of that tank and some of the others.
In this thread I will try to share our work from today until we open the new Aquarium in the fall of 2021.
We closed the museum this Sunday, and our first step is the build a temporary Aquarium in the room where the museum restaurant used to be. Unfortunately we need to clear the old Aquarium facilities before we can move into the new Aquarium, therefor this temporary solution. Our aim is to start up the new tanks with as much "homegrown " corals as possible. And since we're planning on a reef tank with 400 000L water, we will need a lot of corals
Corals corals..
I hope you would like to follow our journey from a small public aquarium to a medium size. Please feel free to ask any questions you want(or tell me I'm stupid if you think I'm stupid
So, here's some pictures from this week, the week after closing.
This is where the temporary Aquarium will be located
Okey, that was the startup of a new thread. More will come!
Best regards
David
Do you mean the stand with the three small tanks? They came from a LFS. We got them for free if did all the carrying
They were just a middle step for some rocks and corals before we got the larger propagation tanks in place. Now they’ve retired.
Lobster eggs, fish eggs, invertebrate food and copepods. All from Ocean nutrition. I wanted to get an idea of the size of the particles. Unfortunately the fish eggs were too big IMO, and didn’t have enough buoyancy. So those will serve as fish food in other tank I think. The rest looked like good coral food.
