question to are planted community, in your experience how much salt can be added to this tank? I know that goldfish are pretty tolerant to salt and I want to start adding small amounts every now and then as a preventative measure, The problem is I don't want to harm any of the thriving plants in this tank. Currently I have Anubis, Java fern, and two large crinum calamistratum. this is a 55 gallon tank with two of my large Ranchu.
