Has anyone used prime while aquarium is still cycling? I have a 55 gallon fresh water tank that I set up about 2 weeks ago using quick start. I wish I would have found this website before doing anything. I planned on doing a fishless cycle but was told at one of the local pet stores that I needed to add a few fish to get things "moving". I did just that and now finding my levels are high. the ammonia is at .50ppm, nitrite at .50ppm and nitrate at 40 ppm. I've been doing partial water changes daily, adding more quick start. I went to another local pet store and they highly recommended using prime for my levels. I did purchase this but have not used it just yet as I'd like to get some opinions on this first. I'm totally confused because I am getting different stories from each pet store I visit. I have researched and have learned that live plants help the cycle process so I did buy a few today. The one petstore says they will do more harm than good in the beginning, the other says yes use them as they will help , they both suggested me not to do water changes until the cycle is done. I have read where water changes are very important in the beginning so I ignored both their suggestions and came home and did a partial water change, adding more quick start to the water . I did not add any of the prime as I would like to get some opinions here of people that actually went through this or are going through this. I really wouldn't be as concerned if I followed my instinct of doing a fishless cycle instead of listening to salespeople saying you need fish to get things moving. I'm just very sensitive to me causing something to die, may seem weird to some but that just me so I appreciate anyone that can give me any advice on what to do next. Thanks!
