2nd Cycle?

[rdaled]

I have had 30lbs of LR in a 10 gal cycling for about 2 months with a heater, skimmer, and MJ.

Parameters:
amonnia: 0
nitrite: 0
nitrate: 0
kh: 10.5
ph: 7.9
salinity: 1.024
temp: 79

I am getting ready to fill the main tank with RO/DI water and mix in the salt. I will let the CLS run for a day or so to mix. I also have some aragalive sand that I want to add for substrate. I will probably add the LR first and then fill the sand around the rocks.

What should I expect at this point? Another cycle because of the sand or should it maintain exsisting parameters?

Probably will not see any issues as far as the water chemistry goes, although the new real estate will go through algal succession as the different organisms compete for space in the sand bed. You may see some surface blooms depending on the availability of limiting nutrients for algal growth, but it will just be a series of successions that would normally occur as part of the maturation of the tank anyway. Just dont leave your rock out of water for an extended period of time: mini-cycles occur as a result of die-off, so if it (die-off) doesn't occur, the cycle will not occur.

Cool... thanks Tom!
