LR deteriorating ?????

[scubatiffy]

Hi, has anyone had a problem with LR deteriorating leaving a ton of fine dust on the rock? Makes a mess in the tank. Is there something that can be done or is this normal. Water quality is good. LR has been in tank over 4 months. Any suggestions?

The rock my SP came on is eroding underneath the mat. I don't know why and it is the only rock that is doing that.
I guess I'll just have to start fragging soon.

Is the dust in piles, or is it all over the rock evenly? If the dust is in piles then it is probably worms and other critters boring into the rock.

The dust is all over the LR....nothing boring into rock that I know of. Also, coraline has turned white. I use 260 watts lighting, 2-65 W actinic and 2 65 Watt sunlight.
