I am trying to set up my very first tank... I have a 75 gallon tank and am trying to start an African Cichlids tank. I hAve heard Argonite sand is one of the best things for the bottom of the tank... I have rinsed it and put it on the bottom, then i put a bag over the sand, bUT when I start to add water it still gets real cloudy... will the cloudiness disappear after a while and I need to be patient or what should I do? Right now I only have the tank a fourth full because I don't know what to do..... PLEASE HELP!
