I get the same reading in my sump as in my DT.
I saw that after and I'm sorry about that! Was on my cell.
. So I was reading last night and apparently there is some debate as to what higher levels of voltage can do to corals. Common sense would tell me that if it can cause your fish to act strange or kill them then it would most definitely affect your corals at higher levels. Here is what one guy said are some symptoms of voltage being to high. Take into account that all other things were within good parameters for his tank and he had no issues except the high voltage.
Extensive loss of zooxanthellae in SPS
Tissue recession and polyp bail-out in SPS
Shriveled up and discolored soft coral
Complete "melt down" of soft coral
Leather coral shed excessively and will not extend their polyps
Since I don't have corals yet I can't really say if its BS or not. Just thought I would post it!
