I was afraid to hear what you all had said to me on this post and am very relieved.....I will continue with water changes and will look for the biospira. Since my tank has been set up for 5 weeks today, with fish 4 weeks, do i need to do the change on part of my filter. I have the aqua-clear power filter 50 with bio max. You know how it says once a month to change part of it. Either the carbon or the biomax insert. Should I leave it alone? I do have a filter insert in all the stuff I bought that is ammonia remover. Opinons please>>i will also consider the other suggestions and I really appreciate them. Thank you.
