Hi so I just got a 20 gallon tank and I set it all up and filled it. I rinsed all is the gravel decor ect in cold water. The tank ran great and the water was clear and I added the first dose of nurafin cycle. The water was clear and the next day I Added the second dose. The water becAme cloudy and i waited over night for it to clear up. The problem is that its still cloudy. Should I add the third dose and the cloudiness is normal or should I wait for it to clear?

the pics should be atached. the tank looks small but is a 10 gall. one of the pics is when the tank had platies and guppies. the other you can only see one barb because i only had added 3 so far and i only got one in the pic. sorry about the quality of the pics! BTW, my tank water is clear again!
