Yesterday I did the first peroxide wash. I made up about a 7% solution of hydrogen peroxide which was acidified with a combination of acetic and phosphoric acids and slowly poured it over the rocks. I let that sit overnight and turned on the recirculating pump. The amount of slime that came out of the drip system was amazing. Also large numbers of dead fungus flies were flushed out of the rocks. Turn the pump off and pour a second batch of peroxide over the rocks. It sounds like a glass of coke bubbling away. The system is full to the brim with the solution and I will let it sit before flushing. Anything that survives this treatment deserves to live. I will have to get out some rubber gloves to get the pump plumbing to drain mode, since the solution turns skin white and burns.
