A friend's 5 gallon tank has been having a pretty bad algae outbreak. There is hair algae, brown algae and algae growing on the glass and rocks.
If we scrub the tank clean and then add a UV
sterilizer would it prevent another outbreak?
I know it only has an affect on the water, but I was thinking if all the objects are clean then it'd be able to prevent algae from living in the water and therefore getting onto objects. Is this true?
