setting my 40 gal breeder up and i forgot to wash the sand its ultra reef marine sand for fresh or salt water so i put it in and now its not settling here are bad pics will it settle after a few days?
Yes it will settle. It will take time . If the fish are not in there I would use some 5 gallon buckets and remove it all to wash. Either way you can't go wrong its just the tank will get cloudy for a while or anytime the gravel gets touched. which is not good for your filters.
