The condition of the fish tank is dirty, water changes color and green moss due to excess waste, food or too strong light. If not handled promptly, this condition will cause oxygen deficiency and prevent fish from living long. Therefore, housewives should refer to applying physical hygiene measures to bring a safer effect.
Peeling moss and removing waste
The first step is to remove the amount of moss clinging to the glass surfaces of the fish tank. Use a specialized razor or hard plastic card to clean the moss on the glass wall. For moss clinging to leaves or leaves, need to use tweezers to remove it gently.
Immediately after shaving away the moss, use a racket to remove all floating moss patches because if you leave the moss in the water, it will spread spores and grow back very quickly in another location.
Drain bottom sediment and change water
After cleaning the glass, proceed to drain the bottom sediment to remove fish manure and leftover food, the main source of nutrients that nourish the moss. Use specialized straws to carefully examine the base.
Only about 30% of the water in the tank should be replaced to avoid affecting the fish. The newly added water must ensure that it has been de-chlorinated and has a temperature equivalent to the old water.
Clean water purifiers
This is the most important step because a dirty filter system will lose its ability to treat toxins. When cleaning, it is necessary to remove the filter cotton and filter materials (celain, lava).
With filtered cotton, wash thoroughly with tap water to remove mud. With filtered porcelain/biological materials, absolutely do not wash with tap water or soap because it will kill beneficial microorganisms.
You should wash gently with the water just sucked out from the fish tank. With a pump, use a small brush to clean the fan blades to restore strong flow, helping water circulate better.
Adjusting light and food
To prevent moss from growing again, reduce the time to turn off the lights from 6 to 8 hours/day, or turn off the lights completely for the first 1 or 2 days of treatment. At the same time, only feed the fish just enough to ensure the fish eat it all to limit leftover food from decomposing and causing water pollution.
