I just set up my 120 and had a few question to ease my mind. The tank has been up and running for about 5 days. First question, My water is still hazy. The tank currently has no residents and the only thing that was added was some aqua safe dechlorinator when first filled. My substrate is pool filter sand and I also added a few large stones for the first phase of the aquascape. All the stones were treated before I added them to the tank. I washed the filter sand until the water was clear. My filtration is 2 AC 110'S and a Eheim 2260. Any ideas? Or am I just being a paranoid new tank owner? Any input and feed back would be great? Does that filtration sound O.K. for a 120? Last, but not least, what is the best water test kit? When the water clears I was thinking I'd get some Biospira and jumpstart the system. Thanks in advance.
