Betta Fish Tank Keeps Turning Green

Help is gravel growing green algae normal.

Betta fish tank keeps turning green. In cases where you know that one fish has caught this disease using a targeted betta antibiotic can reduce the risk of contagion to other fish. But the tank is overrun with floating green algae. I have a 29 gal tank with 2 small koi a betta and a frog and i do a 75 water change 4 5 days but it keeps turning green.

Introduce algae eating fish snails or shrimp to the tank. There is no algae visible in the tank other than the green water. Performing a 10 20 water change weekly or biweekly depending on the size of your tank is going to help reduce the chance of green algae getting a foothold in your betta tank.

This is why the betta water in many pet stores is often dark blue or green in color shipping is very stressful to the fish and often even under the best care the fish will drop below 74. Too many fish in a tank can also cause the water to turn green. Introduce daphnia to the tank.

Add live aquatic plants. Turning the gravel green why. My tropical tank keeps.

This is a tropical fish tank with a heater. Move the aquarium away from direct sunlight or keep the blinds or curtains drawn. These small crustacea eat the algae and they in turn are eaten by the fish.

I have a biological filter that keeps all the n levels where they should be. I put water treatment in it and everything and change the filter often but cannot figure out why it keeps turning green. Algae growth also accelerates with too much light.
