I'm not very knowledgeable about marine aquariums, but I can recommend checking all the links on: There's a lot of useful information there, maybe something will be helpful.

Thank you for your participation. I will take your advice.

Water can and should be used, the only condition is to control the parameters, mainly salinity, if a freshwater river flows into it. The most challenging aspect of an aquarium with inhabitants from the Japanese sea is the temperature, which is quite low, so the cooling problem needs to be addressed. The standard equipment includes a powerful biofilter and a protein skimmer. What volumes of water delivery to the aquarium are possible? For a longer period, water can be aged in a container for several weeks until the plankton dies and decomposes. For these purposes, a container with a separate filtration system can be made.

I am not a marine aquarium specialist, but I have some general understanding - I think you can't keep living creatures at the maximum possible temperature all the time, because, firstly, it shortens their lifespan (in summer, metabolism at higher temperatures speeds up), and secondly, there are clearly hydrobionts that stay near the shore in winter and go to deeper waters in summer, where the temperature remains approximately constant. Correct me if I'm wrong.

You are wrong. It's not hydrobionites, but hydrobionts.

Well, yes... I messed up...

Hmm, 10-15% once a week without special equipment, just using external filters? I'm afraid that their lifespan won't just decrease, but will decrease quite significantly... If there's no special equipment, maybe 10-15% daily, or at least every other day, right? Moreover, considering the fact that the water needs to be aerated, why not install at least a homemade foam generator powered by a compressor?

You can also put a penny, it won't be worse, only better. But one should live like this if moderation in settling is observed.

What about tests for ammonia and the like, pH, phosphates...

Water needs to be cooled even in tropical aquariums, and in cold-water ones even more so. The only question is the length of the hose and the flow rate of the water for effective cooling. Regular household refrigerators are also used, which turns out to be cheaper than specialized aquarium ones. Ideally, the volume of the biofilter should be one-third of the aquarium volume. A drip system is preferable. At elevated temperatures, not all species can survive for long without adhering to a yearly temperature cycle, but it is possible to find suitable ones. It is still difficult to maintain the water temperature within 20 degrees.

In hydrochemistry, each test includes a description of what, why, and what to do to lower or raise the parameter, and there is literature available, as well as a website where you can also find information and do an online analysis, but it's not very good, so look into it and decide... I also have a question for the moderators: what can be used to glue shell rock and decor; is there a way to secure live rocks, is there anything for gluing wet stones?
