Water Problems

[RBurkett]

Hi,

Can someone help. The water in my tank has started turning a greenish colour.

The Ammonia is 0ppm, Nitrite 0ppm. Nitrate 40 and PH 7.5.

I have the light on for about 8 hours a day and feed my fish once a day {Small amounts}

The only thing I have done different recently is add two assassin snails, and a coconut cave. {Boiled coconut for 30 mins prior to putting in tank}

I am doing regular water testing and a 25% water change/gravel clean every week.

I add plant food once a fortnight and stress zyme once a week.

I have checked the plants and none are rotting, from what I can see.

What could be the problem???

small ammonia spikes that are un detectable on a test kit can cause this. Low C02, ack of nutients. What you need to do is a 3 bay blackout, cover the whole tank. After 3 days see whats going on.

I cannot relate this to being a livebearer problem but have seen posts about green water algae in other areas. In my own experience, I have found green water algae extremely hard to grow. Why would anyone want green water algae? That is simple. I have tried to raise my own daphnia and green water is their favorite food. When I tried my best to give green water a good chance to prosper in my tanks I failed miserably because I could not provide enough light. When I moved a small sample of my green water to an outdoors tank, the natural sunlight was enough to really get the green water growing and prospering. I ended up with water that I could not see my own hand when it was only about 4 inches below the water surface, that is really green in my opinion. If you can control the light getting to your tank, the green water will die back rather quickly on its own. Even with over 12 hours of artificial lighting indoors, I could not get my green water to do well beyond about a week.
