Hey, I'm starting up a reef tank, and it's my first time so I wanted to make sure I don't mess anything up. I just set it up Saturday, Sept 3, and I put 2 30 lb bags of white caribbean sand, and one 20 lb bag of aragonite live sand. Then i put water from the tap into the tank and put water conditioner in it. (I don't have a water purification system YET, im currently saving up for an RO system. Then I got my salinity set, and my two filters running, I have one wet dry trickle system, and one penguin 350 biowheel filter. I let that run for about 7 hours, then I put about 70 lbs of live rock that I'm pretty sure was already cured, for I bought it from someone who used it in a reef for more than 6 months. I also added some of the saltwater that came with the rock to increase bacteria, and also added bacteria starter to the water. I have been testing it once a day, and so far my PH and nitrite levels are good, but my Ammonia levels are at 2.0 PPM. I was about to put some more conditioner in, but I wasn't sure if I should. I'm kind of stuck on what my next step would be. Should I some shrimp or snails for a cleaner package, or should I wait a couple of weeks until I get my levels evened out?
