Hey your on your way
I would go ahead and do the water change
I used cured LR , from my local fish store ( LFS) , and LS in my JBJ bio and had a very fast small cycle also
I think the time depends on how good the lR is. You will be ready for that CC soon! Keep us posted
I have read on here that you can extend your cycle by doing a water change? I definately do not want that.
Also my rock came from the Dr...... and it said it was pre-cured witch means well.....nothing to me. I have read there directions on the live rock and they are saying to do 50% water change weekly???
HERE ARE THE DIRECTIONS....
Method B: Curing process of live rock for the new aquarium that DOES NOT contain fish, corals, or any other marine animals.
Live rock may be used to cycle a new marine aquarium. Follow the manufacturer's directions on the installation of all filtration devices and accessories. Fill aquarium with freshly mixed saltwater with a specific gravity of 1.023-1.025. Activate all filtration equipment, check for leaks, and set heater and/or chiller to the desired temperature of 72-78°F.
Note: Mechanical filtration will need frequent cleaning during this cycling process.
Rinse each piece of live rock in a small bucket of saltwater to remove any loose organic matter, debris, or sand.
Place live rock into the aquarium to create a stable foundation for corals or decorations.
Keep the lighting system off during the cycling period in order to reduce the likelihood of undesirable algae growth.
Gently scrub the rocks periodically with a new nylon bristle brush or toothbrush to remove loose white film or dead material.
Perform 50% water changes weekly while siphoning out any organic matter and loose debris that accumulates at the bottom of the aquarium.
Measure and monitor the ammonia and nitrite levels in the aquarium weekly.
When both ammonia and nitrite levels are zero, perform a 50% water change on the aquarium.
After 24 hours, check the pH of the water and adjust as needed to achieve the desired level of 8.1-8.4.
Those were the directions on the box!!!
