i went to my reef store and they didn't have everything i needed to start a brand new saltwater reef tank...soooo they gave me what they had and the rest will be in in a week...in my tank right now is 25lb live sand..and the salt water...they told me i could let that sit until the live rock is ready in a week...is this ok? should i have something else in the water like a shrimp or anything? it also has a 850gph circulation and wave pump in it.. i have it turned off right now because the water is very cloudy..how long can i keep it turned off? it has been off all day....thank you soooo much..i am a beginner.
