In our records the tapwater in Sofia is bad. You can use tapwater to cook, but it is not drinkable. Please use bottled water.
In Sofia poeple think the water quality is ok. But i am worried that the fish are sick because of pollution from factory discharges. I don't want to eat any fish but it should be safe and healthy. Any suggestion?The fish in our area are quite healthy, no need to worry at all. The only thing that you will have to do is to keep an eye on the levels of ammonia in the tank every few days until you see a slight drop. This will tell you if the ammonia levels are rising or falling.If you notice the level of nitrite coming up too high, then you can try feeding the fishes with some nitrates like table salt mixed in with their food. If this does not help, you might have problems with parasites. You can also look for the presence of bacteria like Escherichia coli in your tank. A couple of weeks ago I was getting E. Coli along with nitrites as well. My advice would be to wait about 12 weeks before taking any action regarding your fish. They wont be affected by the changes in pH caused by nitrate buildup. Just make sure you give them enough water each day so they dont get too hungry. Good luck!I'm afraid that there is no one around who can answer your question. We live here in Germany, where the situation is much better than in other European countries. And we're not far from some of the biggest fish farms in Europe. Unfortunately, the quality of water isn't great either. Some fish farm owners sell their fish to us, but others ask us to buy their animals. So we have lots of questions about the state of our aquaria. However, when I asked someone whether he had seen signs of fish sickness in his fish, he just laughed and said "that's not what happens".There are a lot of things you could do to improve the overall health of your aquarium including buying fish from reputable sources. keeping your water chemistry within certain limits. and making sure that your filter system is working properly. It's always good to consult your local aquarologist first though.
Sightseeing in Sofia is astonishing. The capital of Bulgaria is a fascinating mix of old and new. It has preserved its ancient traditions, but also modernity.The Old Town, the largest Bulgarian city, is worth visiting at any time of day. A walk through it gives you a good impression of how the country developed during the centuries from classical antiquity to modern times. This was the heart of medieval life in the land of Svetitskhoveli Monastery in the area called St Simeonov Monastic University, and then later the centre of Bulgarian culture. Many important historical buildings still stand here, as well as churches, mosques and monasteries. In many places there is also an open air museum with exhibits on Bulgarian history. At night you can stroll around the beautiful streets of this area. If you are interested in more specific areas, you could visit some parts of modern Bulgarian cities, such as Plovdiv, Pazardzhik, Stara Zagora, etc. You may also want to visit one of the many parks and gardens in this region. Here I will describe my favourite places for sightseeing. But please do not limit yourself to just one place! You can combine several places if you like or make your own itinerary. My favourite place for a sightseeing tour is the Black Sea coast. There are some stunning sights along its white sandy shore. Some of these are very special, although they are often hidden from the public gaze. I would suggest combining them with Sofianka Beach, which is so beautiful that I have included it twice in my list. Another option is visiting a traditional village in eastern part of Varna Province. These villages are built around their unique local architecture and have been left unchanged for centuries. They provide an interesting insight into Bulgarian rural life. All these places are listed below. Please read the description carefully before making your plans. As you see, I am not including the main monuments directly in Bulgaria. To do that would be a bit too long and would probably ruin all the beauty of each place. What I aim to show is typical Bulgarian architecture found throughout Bulgaria's history, and how these have changed over the years. By exploring these sites, we can understand how Bulgarians have adapted to their changing conditions. And by observing the way people interact with their surroundings, especially in rural areas where they live, let us discover how people lived in our past.
