Hi guys! It's been a while. Long story short, had a 40B reef, and we sold our house and moved in with my future mother in law so I downsized to a 29biocube. We're in the process of building a house, so my poor tank has been terribly neglected. I'm down to 1 clown and 1 watchman goby so I'm going to downsize again to a 10 gallon. My plan is to use stuff I already have: An aquaclear 30 hob filter 100 watt heater (with dial) might need smaller watt 2 12" panorama pro LEDs Live rock currently in tank Have some powerheads, not sure if I'll need them. I bought new aragonite sand, but I plan to use some of the sand that's in the tank now to "seed" it. My question is, do I need to wait for a cycle since I'm using the same rocks and some sand?
