OK, I've finally got my sons first freshwater tank together and running.(A SYSTEM 12) for almost a full day. I have a PH test kit and it says I'm around 7.2 It was a clear tank last night but today it's a tad cloudy. I really want to add a few Danios to start my cycle. I was told after 24hrs I could. I also read the fishless cycle article. Will the cloudiness go away or does the water need to be recycled before I get the fish? Since it's Sunday I wasn't able to get a hold of the store I bought it off of to ask. I don't use the PH kit untill after I put the fish in correct? or can I try and get it from (Basic 7.2 to Neutral 7.0) before? well, any and all information would be great.
