yeah the tank was really old, i had it when i was a kid....a few weeks ago i was home from school, i filled it with water and really scrubbed it down. i then rinsed it multiple times and added gravel and a few plants and let the filter run....i then emptied the tank completely and took it to my dorm. i let is sit for a while with water and after about 4 days my friend put a gourami that he didnt want in it. it wasnt completely cycled and i warned him about it, but it had killed a few of his fish so he didnt care. this last monday i bought my red minor tetras and put them in the clear water, which then became cloudy. i dont want to overexagerate the water, its hazy, by no means crystal clear like my ten gallon or my two gallon.
it sounds like i should just be patient, maybe the cycle isnt done as i thought. hopefully in a few days it will reach its full potential
