Actually I am kinda supplementing with microbes and beneficial fungus I use the products on the left on top of the pond fish food in the plants roots. I use the products on the right to feed the filter feeders. Each one has something the others don't. A pinch of each with a half a shrimp from the grocery in a blender on high for 5 minutes or so to get the shells all microscopic...the fish eat the filter feeders and the other half of the shrimp with the shell chopped up into little bits. The shell ads important minerals the fish and the crayfish clams need. I do this every other day then let them forage for a day. So far water tests are good.
