I went to pick up some quikrete play sand for my new reef tank but noticed that it contained silicates. I ended up going with the Quikrete pool filter sand. It didn't say anything on the bag about having silicates. I used a different brand of pool sand in my freshwater planted tank and never had any problems. Do you think this sand will be OK to use? It's going to be a reef tank with about 5-10 lbs of live rock (It's a 10 gallon) and quite a few zoanthids.
