I tested the water this morning that is with the sand. Ammonia is .5, pH 7.8, KH 180, GH 150. The grain is very fine and the sand is pretty heavy. I rinsed it well to get out all the extras and if I shake the jar up now, within 10 seconds 95% of the sand has settled and within 5 minutes the water is very clear. I think this would cause compaction issues wouldn't it? I did the vinegar test. Its purely silica based sand because it didn't fizz at all. That pretty much makes it a no-go right?
