I've recently about 2 weeks ago set up my 5 gallon marina fish tank that I got around 4 years ago. When I got my fish tank filled with water with the heater and filter running I let it run for a few days. When I got my fish i made a terrible mistake. I added topfin tap water dechlorinator (even though im on a well) and bacteria supplement the night i got my fish. I waited 4 hours after I added the declorinator and supplement and then added my fish. Yesterday I got myself a API freshwater master test kit. I tested my water and I had around 4ppm ammonia, 7.6-8 ph and 0ppm nitrites and nitrates. Ive read a lot of people who had this problem and I did a 50% water change and do 20% water changes daily. I've recently got into this hobby and want to know a lot more so i can someday own a bigger tank. Any Suggestions?
