so I have 2 tanks with potting mix under sand. One has no issues except huge amounts of diatoms the first 5-6 weeks until I got a couple of nerites and a mystery snail. The other is truly dirty. Peat everywhere. Tonight i increased the BDBS cap by adding a couple of lbs. In the process, I had several chain swords that had runners with 3, 4, 5 new plants with roots. I separated these and stocked 2 other tanks. I cut the runner leaving 3-4 tiny plants with roots and buried the roots. Will they take?
