First off this is my mate and I's first saltwater aquarium. It is 55 gallon and weve had it set up for a couple of days. We plan to start adding coral and other live rock next week but right now we are wondering about this sand that was given to us by our local pet store in a deluxe marine setup kit. The liv sand is so fine that the tank has stayed horribly cloudy for 3 days, I'm assuming this is normal but we are wondering how hard this is going to be to keep clean? Anytime we even arrange the sand etc its a huge dust storm in there and I cannot imagine putting my fish through that when cleaning. Should I have went with a grittier rocky type sand? How hard is this going to be to keep clean? Should we change it before goin any further? Any tips would be greatly appreciated.
