The Official Asylum Reef Tank Thread

I think the polarity in the DIY thread is backward. The negative electrode bubbles much more actively because of the extra gasses from secondary reactions (sodium mostly). Also, chlorine eats stainless steel. I was messing around with platinum wire from a thermocouple and I didn't use graphite for the other electrode but instead just some of the SS I had. The minus electrode of SS bubbles a lot more than the platinum one did and wasn't eroding. If I put SS on the plus side it erodes and gives off a yellow plume. This makes sense to me. I will reverse the polarity on the zapper I made and try it out.
