Hi guys I've made a cell from a microwave oven stainless steel body. The thing is when I'm conditioning this cell alot of mack is coming out of it and the water turns black. I've changed the water several times but still this rubbish is coming out :( . Hope that this stops and the water become clear in electrolysis.
Brown muck: iron in water. Use distilled water.
Black: Nickel and hydrogen.
