At start up I put 100 lbs. of dry pukani into my 220, along with about 70 lbs live rock from my previous tank.
Also put 3 garbage bags of sand, about 70 lbs, that a member here gave me. That had been sitting in his yard for 2 mos., along with about 40-50 lbs from my previous tank.
The initial cycle was not bad, and that was 16-17 mos ago, still haven't needed a water change. I actually put bio balls in about 6 mos ago to try and get some po4.
