Thank you all for the replys. I thought that the nitrite test turning greenish color every time when I added ammonia means too much nitrite for nitrate to convert into.... I will stop WC right away. As long as I know that I am getting close to the end, I can hang in here a little longer. Do I still need to feed ammonia everyday or should cut back a little?
I have an HOB filter with a bio wheel. I stuck some parts of rock wool from the plant pot and new filter floss at the empty slot where you can use to put your second cartridge. I don't know if they are considered as bio media. I am still leaning...Is it ok for me to put a ceramic ring or bio ball in the bag and stick it in the filter?
Instead of reading everysite on the internet for 3 weeks trying to figure it out alone, I should have posted a thread here sooner. You guys are so helpful!
I'm fairly new to this site and have learned so much! Welcome.
There are many different opinions about bioballs and ceramic rings. I use ceramic rings in addition to filter floss because I personally look at it as some added insurance for the housing of bacteria. The bacteria will also live in your gravel, on decorations, and on plants - not just in the filter. The ceramic won't contain bacteria yet, but will give a nice cozy place for it to live. What temp is your tank, bacteria like it a bit warm. When I cycled my 20 gal I upped the temp to a bit over 80 degrees for a while and then backed it off for a few days before adding live stock. And yes, keep adding small amounts of ammonia.
