water changes
 

New to this quick question, should I be doing a water change my tank is going through it's first cycle. Nothing in it just 18 lbs of LR, and Sand.

How long has it been cycling?

I don't think you want to do a waterchange until your cycle is complete.

Unless levels get really high....but as long as your skimming you should be good....
