Can someone help me with my understanding of what one should use as a substrate for DSB
My wife really wants me to try and find a white sand. I have read some of the posts that state that a type of sand from Home Depot is a great choice. Unfortunately, our local Home Depot only has Sakrete Play Sand, not the Southdown. My wife, by the way, really wants me to use a white sand if it is available. I have the option of using sand from the Gulf of Mexico since I am only a few miles away, but my wife wants a whiter sand. Sand from the Gulf has the obvious advantage of coming with critters that could be very beneficial. However, my wife wants a whiter sand. I have seen a white substrate at our lfs
, but it might be crushed coral and it is rather expensive as I have a 90 gallon aquarium.
Thanks in advance for any help.
