well, i didn't understand what kind of problem u have. R u having problem with the cloudy green water or about other problems? if its about the cloudy green water, then i can tell u that its algae thats creating the problem in ur water. When the nitrite levels r at resonable range or exceeds higher or ur providing excess light or heat in ur aquarium, this causes the algae to grow. Excess algae causes cloudiness, to reduce them do frequent water changes and cut of light and lower the temperature. This would lower thier population. One good advantage is that algae is the favourite food of goldfish, since ur having them and removing the algae, ur goldfish would also help you out to clean the algae! But then, if u have other problems u ought to mention it.
