This product is the best way to prevent your fish from dying due to New Tank Syndrome. Install a biofilter. Get these, Seachem Prime and Ammonia Warning (Seachem does it, it just hangs in your tank) to measure free ammonia in your tank (most tests measure free and combined ammonia, and if you have combined ammonia and not free , you will get a false positive with your test kit, only the free one is toxic) and your fish will not die. You know exactly when your ammonia and nitrite levels are high and you have products to counteract it. I also recommend Purigen bags and/or Seachem Matrix Biocarrier (wash the matrix well first) to put in the filter, they really clean the water and help reduce ammonia. I recommend buying an API master test kit, but not for ammonia but for nitrites and nitrates.
