Live Rock Bleaching

The tank is on its second month.

I use a single tube of 24'' T5HO and the light is suspended about 4'' above my tank.

I'm going to go out on a limb here and say that you need more light for sure!

Yeah it may need some more light. Do you know your parameters?

Thanks for the replies.

My parameters are all in check and has been relatively the same since the inception of the tank.

I am guessing it is not getting enough light. Whereas in the first month, I had the lights on for a much longer period. I will try to leave my lights on for longer and see if that will change anything.

I would saw its not so much about the length of time but the intensity of the light. If you can, add some more light.

Is that so?

Because when the rocks first came, there was almost zero Coralline Algae. Then as time progressed, more and more started to develop and grow. It was only until recently where the rocks began to turn white and bleach. So I think what I did was decrease some of the photo period...

So I am unsure as to what might be causing this?

I think calcium might be an issue. I am no expert but that light on a 10 gallon seems fair enough (2.5w/gallon + shallow tank). Maybe your should do a water change (if you didn't do it for a significant amount of time) or check the calcium with a kit.
