I purchased 40 lbs of premium deco rock and mistakenly thought it would only give off a small amount of ammonia, it came up over 8 ppm the next day. so instead of refilling the 40 i filled a 20 gallon with about 15 gallons, scraped all the dead on the rock and rinsed them in a tub of salt water. day 2 i check and im only seeing 2 ppm of ammonia, my question is am i ok to go ahead and put it in the 40 assuming the ppm will drop by more than half in the tank, or will it leach out and increase over the next few days? ive never cure live rock and ive heard it takes ten days so idk
