Purchased 13 lbs of tonga and fiji LR. added 11 lbs of aragonite. (LS) in a 12 gallon jbj nano dx. this setup has been running for 10 days now. i have tested nitrite, nitrate and ammonia everyother day, all readings have been steady at "0" since day 1. ph is 7.8 to 7.9 no coral or fish. there was a few dead organisims on the rock when i purchased it so i had lightly scrubbed the rock in r.o. water. (the rock was never out of water more than a few min). the lingering question is might this tank ever cycle? i have read the nitrites and ammonia should spike then fall back down. have not done a water change yet. not entirely clear on how to raise the ph. i know its to soon to be adding buffering agents. i have "reef builder" on hand.
