I was just going to buy a hand held unit. There cheap and I think it would be ok just to have a little more of a understanding if thing are going down.
I do wonder if people control the ORP. with peroxide or if they let it run its coarse. After all its pretty much a balance of good and evil. I have a very small tank buy our standards and its 90% sps. I crashed once and really only speculate what it was.
