We just purchased a 120 gallon tank and want to set up for SW. The filters are in, we have aragonite sand in the bottom and the hydrometer is at 1.021. What's Next? Do we need to add rocks or coral or plants? If there are any good books out there please let me know. I have read that you can seed the tank with household ammonia. We have the test kit but don't know what we are testing for. Thanks
