Cold temperate tank system in Sweden

[cobast]

If it´s not intersting I will stop at once.

Your posts are already VERY interesting. Keep posting.
I live on the coast in Sydney Australia and often fossick along the rock pools checking out all the interesting creatures thinking could I set up one at home. Water temps are 16 to 25 C but well into the 30s in the rock pools in summer.

Thanks to all nice comments! It warms a cold heart

I am also originally from the Swedish west coast and it was always my dream and still is to keep these beautiful cold water wrasses in an aquarium. I wish you all luck and I will definitely follow your thread.

Hi fellow swede! Hope you can fulfill your dream one day. Wrasses are so beutiful and interesting.

It's so fun to look into rock pools. You must have fantastic animal life there.

Back to the aquariums. I have four 25 liter (7G) with smaller animals, one 50 liter (13G), 200 liter (55G) and one 540 liter (145G). All have a temperature around 10 C (50F) right now.
This is small tank (25L) number two and is designated to sponges. But I have some troubles right now, but hope to solve it. They need very small food, so I have started to dose vodka and soon KZ Sponge Power. To be continued.

Sorry for the cloudiness. It's coral snow in the water.

A small crab that mask itself with whatever it finds. In this case, sponges.

Love this, thank you, so refreshing to see a different style “reef tank”... Hopefully you will inspire others to share as well

I hope so too!

Well I forgot the fish!

What species of fish is this?

 

[Silver Dollar]

It is probably a juvenile Myoxocephalus scorpius, short-spined sea scorpion. Can eat almost everything...

 

[Goby-won]

Very cool!

25 liter, anemones:
This is my third aquarium and it holds some anemones. I had a beautiful sea sqirt, but it was eaten by a nasty anemone.

Dahlia anemone, Urticina felina

Ascidia mentula

This is my fourth aquarium. It holds mixed animals, to small for the large aquarium.

We start with a starfish, Henricia spp.

Two beautifull brittlestars. Too bad they only show them selfs in the night.

Ohh, and I have a reef of cup coralls

A hairy hermit crab.

Can you see the squat lobster. Its just under the cup coral

A small, small wrasse.

Full picture.

This is the stand for the small aquariums.
Light is T5-tubes, but only lit when looking inside. All other time it is off.
Water movement is made by air lifts only, so it is pretty moderate. No skimmers, but water changes is 50-70 % every week done by a semi automatic system.

Very, very cool! Very refreshing and intriguing to see a cool water biotope. Very rare and difficult to do here in the U.S. for those of us who don't live near the coast.

Luckily we will get to experience it vicariously through your posts. Please keep them coming!

Nice to see your kind words! It's an fascinating world to explore, and I'm lucky to live so close to it.

50 liter, mud:
Most of the ocean floor is filled with grey mud, and it doesn't look so much. But it is captivating...

I made a "mud snapper" and went out with my small boat on the sea. Got some mud at 20 meters depth and put it in the aquarium.

It got a little misty...

The mud contained a lot of small brittle stars that put up their arms from the bottom. A little bit scary...
Hope this Youtube will show


A small digging sea snail, pelican foot:


I got lucky and found some sea pens, but they were damaged when captured. So they didn't make it.

A small goby who occasionally lives in symbios with a lobster was also caught when getting the mud.

He makes his own cave in the mud:

A couple of weeks ago I noticed some new animals in the mud. Not sure what it is yet. Perhaps a kind of sea pens and there are about ten of them.

It bury the big round foot in the mud.

Man, that's wild. Can't do that here. LOL. Don't have boat to do that and ocean. Love it. Thanks for sharing.

Very interesting. The sea is an amazing place and full of life!

In the first post I promised a build thread, oh well. It's all finnished, but I can give you some photos.

Two aqariums are standing in a basement living room and a sump common for both tanks are situated in a workshop. So first thing was to drill some holes.

I love these parts!!

The sump and the equipment.
Skimmer, sulphur filter, oxidator, filter sock, return pumps and ozon generator.

Some plumbing.

Pipe is going to the aquarium to the right in the picture.

Pipes going through the wall and to the tanks.

A happy engineer.

Overflow box in the 200 liter tank.

Double glass on the front to avoid svetting.

The pipes need insulation as well.

Water in the system

I do HVACR, and gotta say, "Man, I wish that was mine." Very nice
