Sorry if this counts as posting another thread, but I really need some responses before my opportunity escapes. I have a 29 gal tank... you can read about it here. http://www.fishlore.com /fishforum/aquarium-nitrogen-cycle/59783-cycle-cycle-cycle.html But, my cycling has hit a bump in the road. Yesterday, I added rocks and took out a large fake wood piece used as a seed decoration and my ammonia began to rise. It is currently at 4.0. I have been trying to cycle tanks since August (my 10 gal) and still have not had any luck. SO, I am hoping I will have some luck with the Tetra Safe Start I just bought at the LFS. I also bought some Aqua Safe. I need a little filling in on the TSS. 1) the bottle I bought for a 30 gal aquarium is enough for my 29 gal, right? 2) do I need to do a water change before adding the TSS? If so how much? (thanks for the answer thorpbrian) 3) do I add ALL my entire stock when I get my fish? Finally, I know not to use the TSS until I am ready for fish... my first thread was SO confusing... sorry! p.s... Sorry for earlier... I was kinda freaking out. I had posted a question about TSS on my first thread without any responses... then my mom started yelling "IF YOU WANT TO GO WE HAVE TO GO RIGHT NOW"!!! So, I left and got the stuff and now I am cleaning up the original post... sorry if caused any undue eye trauma.
