Ok well i set up a 20l tank to house a pair of perc i got. (Thank you boogie) I have them in my sump right now as i have other clowns in my main tank. I was trying to get the 20l set up ASAP as i dont want to stress them out very much. (skimmer and pump noises in the sump). so i cleaned the tank spotless using 2gal of vingear. I put in about 30 pounds of what the bag said was "live sand". I was hoping for not much of a cycle but of course my amonnia this morning was around 2ppm nitrates were 5ppm and nitrite was 0ppm. So my question is do i need to add some shrimp or maube some frozen brine to make it go faster? I also plane on adding LR will this help speed up the cycle? I have some in my sump but the clowns are using it for shelter at the moment. oh and i am using a HOB with just filter floss at the moment which i am either going to eventually plumb it into my stock tank sump or i am going to set up a 10g sump for it. but also befor i get into doing that ill probably run filter floss in one side of the HOB and maybe bioballs in the other. let me know your thoughts thanks!
