We are setting up a new 190 sw reef with 120 sump/refugium. Husband is working on the plumbing/set up as we speak.
We found Old Castle white playsand at Home Depot. It says "warning, may have small amounts of silica". Is this the right sand? I know that there is a test with vinegar that we can do on the sand, can someone fill me in on the details of how to test? We brought a small sample home.
Thanks.
