Hi everyone so on 9-17-23 I got my first saltwater aquarium wet. I’m using a 16 gallon bio cube with coralife rock and caribsea live sand for a bio filter. I also have stock bio cube filter in the tank and am using seachem media my LFS recommended me. On 9-18-23 I added dr Tim’s one and only nitrifying bacteria per instructions, and added the dr tons ammonium chloride as well. Things were looking normal the next day. And the following day I dosed ammonia for the second time. The 4th day I had already started seeing an ammonia spike and started measuring nitrite in the tank as well. I was surprised to see it and then on day 6 I was reading numbers much higher for both ammonia and nitrite so opted out of a third ammonia dose. Today is day 7 and I’m measuring ammonia at 2-4ppm and nitrite still reading the same as day 6. However I measured nitrate today and for the first time im seeing measurable numbers of it. It looks to be at about 20ppm. I’ll attach a picture with my test results today(not including ph I already measured it at 8.0 today). I guess I really just want to know if the numbers I’m seeing in my tank as of right now are okay or if I did something wrong and if so what should I do? I’m using the API saltwater test kit which I’ve heard isn’t very accurate but wondering if anyone has had same results as me on day 7. Thanks everyone.
