• The project "Black Sea in a Drop of Water"

  • Jamie3553

The essence of the plan is a 30-liter aquarium, a 50-liter Chinese pump, 50% Black Sea water brought in, and 50% that I will salt. Sand and stones from the same region. The planned inhabitants are 2 green gobies, shrimp, and various small creatures. The question is, which salt for the Black Sea is better to use? Your opinions, suggestions, and advice are welcome.

As for the salt, it doesn't matter which one, Red Sea or Tetra will do. 30 liters is very little for greens, and they will dirty it very quickly, plus it's unlikely that shrimp will get along. For your volume, only a few shrimp and a couple of small fish and anemones or hermit crabs will be suitable... and it wouldn't hurt to read the relevant topics, otherwise everything will die quickly there, as one pump will not be enough...

Tina

Then it's not a problem to take the greens; I'm specifically interested in the invertebrates of the Black Sea. Shrimp, amphipods, and others. I know the volume is a bit small; what do you think, will it be enough for 4 shrimp and 2 hermit crabs?

In this setup, I have three hermits, three pom-pom shrimp, two small anemones, and a little dog. The pump with a sponge has a capacity of 300 l/h, and I do a 30% water change once a month. I placed a considerable amount of porous stones, transporting them in water with a compressor on a battery. There were some plants, but they were successfully eaten. I forgot one thing: the sponge on the pump needs to be rinsed with boiling water every three days, otherwise, nitrates will spike, and I feed the inhabitants very sparingly.

And if it's not a secret, how long have they been living like that?

Erica752

We lived in such a company for 2 months, there were two little dogs. Now one little dog and the shrimp and the hermit crabs have moved to a 70L tank, while one little dog with one shrimp stayed in the 30L tank. Unfortunately, the shrimp recently disappeared without a trace. I suspect it was not without the help of the dog, who feels great, is lively, and is always in sight.

I don't think the puppies are involved here, unless it's a puppy-peacock. My sphinxes and incognitos don't pay attention to the shrimp and only occasionally chase them away when the shrimp get too bold!

Cheryl

Do plants tolerate increased density? In particular, how did I determine that I have Caulerpa? What density is needed for Ophiuroids? I will solve the aeration issue in the coming days, as the compressor is currently running almost constantly.

Bethany

At first, charcoal won't hurt in the filter.

Charles894

Plants can withstand (I mean caulerpa). For ophiuroids - I think in my head that even Black Sea density will be enough for them. You're right - a foam maker! At least the simplest/homemade one... And not just because it will produce super foam, but at least because it will saturate the water with oxygen well!

Regarding the brittle stars... it's quite interesting whether they can withstand such salinity, otherwise I would have gotten some for myself) as for the black algae, the situation is rather tough - they don't want to grow in aquariums.

Worms can endure, but brittle stars won't last even a month! Black Sea algae grow; create good lighting, and LEDs and various bulbs are more than enough, a self-deception to calm oneself, thinking it will be fine. But about 85% of the algae in the Black Sea are seasonal, while some are perennial. Read about how I started with the Black Sea and transferred it to a reef. And it's interesting about the Black Sea aquarium.

David7773

Thank you. But I've already read these topics) Which specific algae are the most perennial and resilient? And how many watts do I need at a minimum for them? It somehow doesn't look very good in the aquarium without algae(((

Chad4168

From Black Sea algae, this 1. This is the green alga Enteromorpha sp. (Bright lighting) 2. The red alga Phyllophora nervosa (moderate lighting) 3. The broad-leaved green alga is Ulva rigida (sea lettuce) (bright lighting) As for the watts, I think at least 250 for a column of water 45 cm. In the sea, guys, there is never too much light; you need to choose the right spectrum, and Crimea is subtropical. Post 6, there is a dog sitting on the alga, Phyllophora nervosa.

Tropical species can tolerate a long-term decrease in salinity down to 21 parts per thousand, provided the decrease is gradual. Brittle stars will not survive at lower salinities, but you can catch Black Sea species. The same applies to an increase in salinity; all invasive species can withstand the transition from Black Sea water to oceanic water, but endemics cannot (endemics include all gobies without a swim bladder, which are easier to transfer to freshwater than to saltwater). Diogenes can be fed with leftovers, as they are satisfied with food scraps, benthic organisms, and periphyton.

And the sphinxes? Will they live normally?

Laura3615

normal.
