I'd bought 2 bags of the midnight this time last year and they sat in my garage,,, just put them in a 39 gallon hex tank this evening... Lord what a mess, minimal rinsing my butt..... rinsed, filled drained filled drained then filled and drained at the same time for about 90 solid minutes.
looks good now, but it is hard and sort of sharp on my hands... I think for cories or loaches I'd go with Saf T Sorb...... it's cleaner and softer. w
this tank will be quite dramatic when finished, it certainly was back when I had special kitty and sand cap in it a few years ago.
