Caribsea special grade sand opinion?

What's everyone's opinions on this sand? Upgrading my tank and starting with fresh sand. Is this sand OK for gobys and snails? Pics would be great if your running it!! <br />
<br />
How much should I get for a shallow sand bed 1-2" in 54 corner? <br />

It would be fine for a Goby and Snails. I have used something very similar. Read the reviews on Marinedepot site.

Unless you are going to be using the Jaubert/Plenum method of filtration, excessive amounts of live sand should not be used. The sand bed becomes too thick, which allows unwanted DOC's (dissolved organics compounds) to get trapped, that in turn can contribute to the growth of undesirable micro and macro-algae. Here are some suggested amounts of live sand to use:

• As the author of "Simplified Reefkeeping", Robert Metelsky recommends a thickness of approximately 1-3/4 to 2 inches, which calculates to 1.45 pounds of sand per gallon. For a 55 gallon tank, this is 80 pounds.

I use this sand, and I like it.

 

Thank you!

I believe I have this type of sand and like it!

 

The first and third sand are dry sand which will need to be rinsed thoroughly.The second is a wetpacked "live" sand with bacteria present to help speed up your cycle.(debatable)
Be aware the live sand requires no rinsing but must remain in sw.

 

The dry is more due to wet weight correct? I ha e sand I can seed from my tank...

 

Any place beat this deal?
