Water for aquarium fish should be maintained in a constant composition, which will regulate the amount of organic impurities in it. Biological equilibrium can be achieved through filtration and regular water renewal. Proper renewal of water in an aquarium with fish is the key to their health and good life, because this procedure preserves the mini-ecosystem of the home nursery.

Types of replacement in an artificial reservoir
Replacing water in an aquarium is an indispensable component of its content. There are 2 types of water changes. partial change and full change.
- Partial replacement in a freshwater aquarium maintains the biological balance of the aquatic environment, despite the often changing composition of the fluid. Before changing the water, from the moment of its first launch, you need to wait two months. Correctly update the water 1-2 times a week, no more than 20-30% of the total. It is often dangerous to change water. it usually leads to deterioration of water quality and neutralization of beneficial microflora.
See how to make a partial replacement of water in the aquarium.
A complete water change is required during a scheduled restart.
Aquarium water: how to defend?
How much time to defend the water? Everything depends on the type of fish that will settle in the reservoir, on their requirements, on the whimsical nature of aquatic plants. after all, the fish often live with plants, and they are almost indispensable. If it does not meet the pH level of 7.0, then it can be defended for 3-4 days until the chlorine and phosphate compounds evaporate.
Aquarium water: what you need to know about the big replacement?
A large water change is the renewal of a significant amount of fluid that occurs in stages over a period of 5-7 days. It is necessary to change such water when there is a need to lower the level of compounds accumulated in the water. Often after a big replacement, the fish become healthy and active. However, changing the contents of the reservoir is not recommended very often.
In a 100-liter aquarium with a small amount of vegetation, you can make the following replacement:
Drain 80 liters of old and add 40 liters of new water, add another 40 liters in a day. But this option is unacceptable for reservoirs where there is a lot of vegetation and fish. In this case, it is better to update 60% of the volume once.
Recommendations for replacing in saltwater aquariums
Sometimes you need to change the water in an aquarium with sea water, if it is in the house. Replacement should occur at elevated concentrations of nitrates and nitrites. Updating a saltwater aquarium does not go as it does in a freshwater aquarium. Properly used with distilled salt water or distilled through reverse osmosis liquid.
Whimsical hydrobionts and sea fish will not be able to live in tap water. Without prior, multi-phase filtering, it only hurts sentient beings. Replacing water 1 time per month (10-20%) of the total volume of the reservoir is not particularly effective with heavy pollution. In saltwater aquariums it is better to replace a large amount of water.

How to know that it is time to update the aquatic environment in a salt water tank?
How much time must pass to have to renew the aquatic environment in the marine tank again? The first is to check periodically observations and tests using reagents. The pure water dissolves salts that contain: MgSO4x7H20, sodium chloride, potassium bromide, MgCl2x6H2O, SrCl2x7H20, sodium carbonate, calcium chloride, potassium chloride, boric acid, sodium hydrosulfite (acid salt), sodium fluoride. These components are part of the artificial sea salt, which must be added over 3 days gradually, one after the other. But this option is very difficult for beginners. In order not to harm the fish and plants, there is a second way. to monitor the quality of the tank (whether there are greens in the water, foam, haze, droppings), its purity and smell.
Also make sure that the quality of the filter has not changed (both mechanical and biological). High-quality filtration prevents severe contamination, so there will be no need to completely change the fluid in the pond. A good filter restores the biological balance of the nursery, making it suitable for further use.
