Your concerns are more significant than some may think so. My only concern is to fill this "lagoon" with local fishes, catched in the nearby sea. I dont intent to bring some exotic species over here. Secondly the waters are not poluted, so there is not any change to pumb poluted wated into the tank. Also, I dont think that the sea has to be afraid of my actions, because if I manage to achieve the same environment to the tank as the sea, then there is no reason to add even one ml of toxic, chemical substance. If there is a way to have the fishes there, and to live without an external help then everything will be ok and I will proceed to completing my plan. If there is no way to mantain life there, without external help, then I am afraid that I have to leave the fishes in the sea. The magic word here is the interchanging of waters, which will hapen continuously, because there will be a 24/7/365 communication of the tank with the sea by a large pipe. I dont know if it is gonna work, thus I would like more ideas. Do you think that there may be a chance for the creation of a suitable environment (O2, CO2, PH) by only allowing the tank to communicate realtime with the sea. I will try to put the tank deep enough in the soil in order to have the upper part of the tank at the same level as the sea, and thus no power will be need for the water that will come in and out of my tank.

I will use the tank also for fishing . It will be very interesting to go fishing at Cristmass at the tank . The fishes are very clever and they cannot be catched with the "usual" fishing methods, so I will have the chance to breed them and catch some of them during the year for eating

Could you give me an estimate of what hardware do I need? What I have to do in order to expand the life span of the fishes? Which is the best method to keep clean such a large tank? PH, temperature, PO2 and PCO2 will be at normal levels because there will be communication with the sea? Thanks in advance

Hello again, The climate here is very mild (we do not have acid rain or tornados ) so there is not really any great threat for this project. The area cannot be reached by most of the people, because it is far away from any location with tourist interest and there are not any wild beasts over here. I live in Greece and there is not any significant reef nearby. Thus I would like to create one . I know that is difficult to create a very detailed microenvironment like most of you do, but I would like to have all these common fishes which live to the sea in front of me, to my “private” sea . So realistically speaking I would like to create more like a sea “simulator” than a reef. Any more ideas are more than welcomed

Hello everyone I live near the sea many years now and I enjoy the “communication” with the water and its creatures. That’s why I decided to create a saltwater aquarium. My problem is that I want to create a very big, lets say a huge reef tank, that cannot be housed inside my home. I have the following vision: I own a piece of land very near to the sea. It ends just 2 meters from the point that the sea ends. It is elevated approximately 1 meter from the surface of the sea. I am thinking to bring a bulldoze in order to create a large pit with the following dimensions: 8 meters wide 5 meters length 3 meters height If you do the math (8 X 5 X 3) you get 120 mm3, or 120.000 liters. My idea is to pump this amount from the sea. I will have a tunnel created by pipes that will allow the communication of the tank with the sea, and thus there will be realtime interchanging of the water. The walls of the tanks will be made by cement and the whole tank will be putted inside the soil and will have a large shadow over it by the nearby trees. The fishes will be caught from the nearby sea. I would like to ask if you think that the whole system will work. What are your ideas to this? Could you give me some advice? Thanks in advance
