Well I have been cycling my Rena XP3 filter, in preparation of setting up my 55 gal tank. It looks to me to like it is doing well and I get the sense that I might need to start doing water changes from the bucket to keep the Nitrate levels down and help prevent an algae bloom. Here is a link to a copy of my spread sheet with all my water test results. Fish Water I will me moving the filter to my tank on the 26th just as soon as the tree is down. I then plan on letting the water cycle through til the 28th, and if the water test good then adding the first school of fish to my tank. That being said should start doing water changes on my 5 gal bucket right now to help prevent an algae bloom? What should the the ammonia and Nitrite levels be? I am sure that I will have more questions as the time gets closer. Thanks for all the help and great information that y'all have been providing me.
