I rinsed the trays ,pumps, tanks, and plants w/ H2O2 29% and water , And I already have new white roots. I keep flushing w/ H2O2 and adding 1/2 cup per tank every other day. This morning the musty bad smell was gone. Not only that but I had a swarm of wasps and ladybugs and I haven't seen an aphid in several days. Also I have good new growth on almost every plant except one tomato plant.
