I bought a 1 and a half gallon aquarium with two Guppies . Of course the pet store did not explain anything to me so I lost the first guppy overnight which I think was not right to begin with she kept swimming and then falling to the bottom . Then I went to a different store to get another guppy to keep the other one company . Well he died the next day. Really sad to see this happen but it has been 10 days now and the third guppy is doing great . I have been doing much reading on the internet about guppies and setting tanks up and bought a 20 gallon tank for some guppies ,and decided I am going the fishless cycle, I do not want to see any little fish die . I have a question about the ammonia levels in my small tank with the one guppy it reads 4.0 ,I am fasting him one day a week , so he can clean his GI system out . I am feeding the flaked food just enough for him to eat in a few minutes once daily . I added ammo lock yesterday but the ammonia levels today were still at 4.0 . Should I be concerned and is there anything else I can do to bring it down to Zero?
Also My 20 gallon has been running for five days and I just added 4 ml's of Ammonia, to start the cycling and have it at 78 degrees . I also added some bacteria called safe start . I have instructions on testing and adding ammonia for the levels to go way up and then eventually reach zero going up and down with ammonia .Several sites I have visited and read had so many different posts about how to go about fishless cycling ,but I finally understand what is needed for the fish . I know it takes about 4 weeks or so for the cycle to finish and then I have to do a big water change as well . Also they say a inch of fish for each gallon so how many guppies do you suggest can be in a 20 gallon tank ,of course for now I am getting all males not ready for breeding yet .
