I've been doing a fishless cycles for about 3 weeks now. My ammonia is not dropping. I put in the filter media from the other tank,and some of the fake plants. I also have an air bubbler stone in it. Also some fish food, which I think I over did on, cause the water turned green. I don't have the light on and the tank isn't in direct sun. I did put Algae Destoryer (made by Aquarium Pharmaceuticals,Inc)about 4 days ago. That didn't help. Today I did a pwc,about 15 to 17 gallons. My tank is a 42gallon. I put the dechlorinator in and waited a while to check the ammonia level. It was still just as high (4ppm to 8ppm). The ammonia I used was ROOTO, in fact I did call the company and the lady I spoke with assured me it was pure ammonia, no soap or anything else. Do you think I should get a few real plants or just keep doing the pwc? I'm getting a little frustrated and just need advice.
