I setup a 10 Gal tank at my office. I have 20lbs of LR from liverocks.com. (very nice rock) My question is I am suprised at how high my Ammonia is. It is off the chart at 8. The rock arrived in very good condition. no smell at all. I rescued a few Brittle Stars that came in the rock and moved them to my home tank. Most everything else has died. I only have a PH in the tank for water movement. Do I need a filter? Is it normal to have such high Ammonia? The tank has had the rock in it for a week now. I also have live sand as a substrate. Tank has been running for two weeks now. One week with just sand a water.
Thanks....
