I've stripped my old tank and am now rebuilding, starting with the old rock. It was removed, jetwashed and left to dry. To be safe I’m tempted to cycle it before readding it. I’ve got three big tubs and my plan was to put rock in there, add some water and a powerhead and let it be for a week. Then water change and leave it for another week. One final water change and a week’s rest should be enough to let nasties leech out and have the rock ready for use in the main tank. Questions:
- Can I use tap water or should I use RO?
- Do you think two changes and a week rest is enough or too much?
- Should the final change be salt water so that the rocks can absorb salt water in readiness for addition to the tank?
- Finally, do you think I need anything other than a powerhead per tub (heaters, small filter unit) etc?
A couple of old rock are still int he tank with corals attached. I want to cut the corals off the rocks so I retain as little of this “unclean” rock as possible. What do you use to cut rock? A hammer and chisel might work for soft corals but rocks with hard corals on would not like that. Is my only option with SPS to snap them and frag them or do you know of a ‘rock cutter tool’ that will not upset hard SPS corals.
Thanks as always guys
