I use the cloudy ammonia from woolies....no problems so far, it is supposed to only contain nh3/nh4, nothing else.
Do you currently have fish in the tank? Anyone else try the cloudy ammonia?
I do - 18" tank - 5 Platies - been in there for a few weeks, no fry yet...maybe in a day or two. This was my test tank for the cloudy ammonia.
And as of this morning a small breeding colony (1M3F) of adult sized Tropheops sp. "Chilumba" (Mphanga), the tank only completed it's cycle yesterday - no ammonia no nitrites and 10ppm of Nitrates. Fish are active and seem quite content in their new tank. Lets hope it stays that way I paid $120 for them
Both of these tanks were cycled using the fishless cycle method - the cloudy ammonia was the only sort of ammonia I could find at the time and the labeling stated it contained only nh3/nh4 i.e. ammonia/ammonium, my water is crystal clear in both tanks and smells "clean". I kept activated charcoal in both tanks just to be sure, but all seems well.
I currently have a 6' tank being cycled in the same manner.
