Im trying to cycle my new 180 gallon with pure ammonia, but i dont seem to be gaining any progress. The tank has good flow, temp 85, wet dry filter, tanks been running for 4 days. I added the ammonia 4 days ago. The ammonia level is 8.0 ppm. Added nutrafin cycle the first day, added good amount of bio media from my established 45 gallon tank (including a filter pad) into the sump. My problem is that the bacteria doesnt seem to be growing, as the ammonia level hasnt changed at all yet. Theres still no nitrites after 4 days, even though i even added lots bio media from my old tank. Any suggestions? I might just drain the tank and cycle it using fish.
