![]() Just a quick newbie question guys. I just picked up my live rock at J&L's on Friday. They said it was about 75% cured. Should I leave the lights off for a few days or keep them on only a few hours a day???? Suggestions?

![]() Hi,
IMHO, I would keep the lights off and turn the skimmer on full blast. Although the rocks may be cured, your tank/sand is not cured. So, I would also monitor the nitrate, nitrite and ammonia levels. When ammonia and nitrites are zero, then your rocks and tank are cured. Hope that helps. - Victor. |

![]() Hmmm, sorry Victor... I'm still confused. From what I've been reading this is "cycling" the tank. I put the rocks in and tossed in a shrimp (the food variety). The ammonia, nitrates and nitrites are indeed rising. My understanding is that the ammonia peaks first then starts to drop, and the nitrates peak a little later and then decline as the critters that break that stuff down begin to multiply on the rock and in the sand. After a month or so all three should be down to 0. Now to restate the light question. Are you suggesting that I keep the lights off until all ammonia, NO2 and NO3 are down to 0? i.e. in a month?

![]() Ray,
Not to help confuse this anymore but...I cycled my tank with the lights on. I thought why would I want to cycle the tank and then turn on the lights only to have to go through the algae cycles. With the lights on, I maximized the life on the rock and had the hair and other micro algae cycles occur faster. Scott |

![]() I cycled with the lights on. There are many ways to skin a cat.

![]() Hi,
My reasoning for turning off the lights is that I don't know if my rocks have been cured properly. They may have been in the curing tank for 1 week. So, there might be some die off in the rocks and that could (remotely) lead to an algae bloom. To your questions...yah...for a month or until nitrite and ammonia are zero. I know it is kind of wierd. Some people cure LR in the dark, so it is not too wierd. IMHO, I believe that the important criters that we want from the rock are not photosynthetic. Since we are not suppose to have any fish or corals during the curing stage, I felt that I didn't need light for the curing. Coraline might die off a bit...but it will grow back. Make sense ? Hope that helps. - Victor. |
