Hello. I am glad to be here. I had a saltwater tank running for the past 6 years that I decided to convert to a freshwater tank. I cleaned the tank, filter and put in new filter media. I put about an inch of old, dry "live sand" at the bottom. I filled the tank with fresh water (conditioned with prime, stress guard, and added a biological "jumpstarter"). Oh, and I added 10 teaspoons of salt in preparation for mollies. This was Dec. 31. The next day, I added the fish - I know that is not the best thing to do, but I gave in to my kids' pestering and did it anyway.
My question is... shouldn't the nitrogen cycle have started by now? I tested the water tonight and all of the parameters seem too good to be true. The water, which was so cloudy before, has also cleared up. I have 2 thoughts... either it is too early for the cycle to begin, or there was already biological matter in the filter tubes (which I did not clean out) which helped complete the cycle in a short amount of time. What do you think?
Oh, and my fish are a bit itchy and are flashing a bit, but no visible spots or velvet.
Here are my details:
75 gallon tank converted from saltwater
5 plants, 5 mollies, 2 gullies, 2 platies, 2 teteas
