Hey guys, been cooking about 140# of LR now for about 5 weeks doing weekly 100% water changes. This method really does work. The rock is becoming cleaner every week. It shed like crazy the first few dunking/swishing water changes. It is also still shedding a little. It will be nice if there is no algae breakouts once it hits the display about 3 weeks. Anyways, pic after 5 weeks of cooking, and you can see the color of the water beside the rock after the dunking...nasty
