Would putting in a water lily help in getting the cycle going in a 75 gallon tank? Does it matter when you cycle a tank if it's not heated? (house tends to be about 76 degrees F - we have AC but don't run it real cold). The water lily is just sending up leaves, & it has a sort of rootball which I imagine has lots of bacteria in it - it's been in the 100 gallon stock tank in our backyard for over a year, which has 5 goldfish in it, & has been maintained by frequent water changes. I am going to put Dr. Tim's One & Only in the tank also. How would using this sort of plant affect adding in ammonia? Can water lilies do OK indoors? Or would it have to go back outside after a couple of weeks? I like live plants, but this is the only one the goldfish don't eat. The 75 gallon tank is entirely for the benefit of the goldfish - once it is cycled, can I add them in all at once, or say 2 first, & then the other 3? They're all about 2 years old.
