I just got a few terrarium begonias and I was hoping to set up some sort of paludarium in a fish tank. Has anyone found a good way to integrate carnivorous plants like pings and sarracenia while keeping their water distilled? I was thinking of adding a water feature with a boggy bottom for the carnivores, but how do I keep the other plants in nutrient rich soil that won’t leach? Does anyone have a method that works? Thanks!
