I have been fighting a major algae bloom for about 2 months now, and I haven't been able to get rid of it, until now...I have been performing a 25%WC a week, cut the feeding in half, and only have the light on for 4 hours a day, and I couldn't get rid of the green water problem...so I figured when I got the time, I would end up completely breaking down the 38g and starting all over again. But, I came home from work 2 days ago and noticed the aquarium wasn't as cloudy-I asked my wife if she had cleaned the tank, but she hadn't. Then I came home from work yesterday, and tank is as clear as it was before the algae bloom.(I haven't performed a WC in 2 weeks!) Whatever the reason is-I don't know, but I am thankful...:thm:
