I am new to this hobby. On 5/24/16 I started a 36 gallon bow front acrylic tank. Followed all start up instructions and choose the National Geographic substrate. Rinsed it as much as possible. I choose to do a fish less cycle, and put some live aquarium plants in there. It took until July 8th to finally have gone through the nitrogen cycle. Thrilled, I bought 4 corys, 2 Mollies, and 3Platys, little did I know some of my fish were pregnant! Now I do see a few fry surviving so far, it's been about a week. Here's my problem, from having no NH 3 on July 14th to 5.0 NH3 on JULY 16th. Just two days!, I do use the apI liquid NH3 andNO2- liquid drop kits. Sat the 16th I did a 25 % water change and added Seachem stability. I mistakenly thought changing out my filter and carbon media would help, so I did that too.I rum the Emporor 400 pump. Today, the 17th I check the levels, no nitrite but 5.0 Ammonia. Despite the water change. I added more stability ( bacterial supplement) today. I fear my little fry will not survive this. Any ideas?
