would you use, "used" sand?

Anyone who is not reusing sand, send it to ME!!!!!!! Unless you medicated with copper, that is.

In the past 20 years, we've never thrown out any sand. We use it over and over and over again in all types of setups from FOWLR to SPS and back again. Some people have found it easy to use a low count pillowcase as a colander of sorts, but we usually sit on the side of the tub and just rinse, rinse, rinse.

 

I agree with Greg here. Im still using sand from my first reef. Theres no reason to throw it out unless you dont want to clean it well.

Oops. Srry Renee...

 

We're both the same.

 

Thank you Mr. Bill, that's a good idea. If there is phosphates, will a week be sufficient enough to test?

Yeah, I've seen those online, I would at least need 10 bags..but they won't be as cheap as what I got. I got the whole thing for $30 (basically almost full load of truck). .;D

As far as DSB and SSB, that's a different matter.

Thank you for sharing Renee. I might actually do it.

 

Yep, a week will give you a good idea how much is in there. Keep in mind that unless your readings are abnormally high, indicating that the sand is from a poorly maintained system, you'll still be fine. Contrary to popular myth, old tank syndrome is from poor maintenance; while sand is porous, it's still just sand and lacks the chemical properties to "suck up" phosphates (or anything else) just to dump high levels back into the tank.
