Looks like 0.4 to 0.5 volts from the heater and maybe 0.2 volts from my return pump. The pump could be putting out some inductive voltage due to the proximity of the motor to water. The heater is obviously leaking current somewhere. Looks like I'm picking up a new heater tomorrow and maybe a grounding probe for the sump too.
As for test results, on Nov 8th I had this: pH 8.4 PO4, NH4, NO3, NO2 all zero KH 7

Here's some pics of the corals. This first one was brown when i received it. it has since turned a lighter brown with a touch of purple on the tips but that is as good as it has become.
 This one used to be a nice right green but has since become more of a duller yellowy green.  This frag is about twice as big as when i received it. The tips have turned a bit pink but the rest has stayed beige.  here is the previously red mill that is now more peach coloured.  A previously nice green slimer with blue tips that is now going completely brown.  This frag has grown somewhat from when I received it but colour has not changed at all in the last 5 or 6 months. The tips are a nice green but the rest is brown.  This one has just faded from where it was white with blue tips. The blue is much more faded now.  Another thing to note is polyp extension has not been as good as it used to be either. So I hope the stray voltage is the answer. Will see how things do once I address that.

Pics look like what I am going through. i still think its your Alk I can post some of my pictures but they are the same as yours more or less.
7 is a bit low for Alk I am trying to bring mine up from that as well but my PH is at 8.5 so trying to bump it slowly.

FWIW my parameters
PH 8.5 Alk 7.6 Mag 1350 Ca 420 Strontium 6-12 Hard to read PO4 0 No3 0.2 My LPS and clams are looking great its just my SPS and they are coming back slowly after the Alk drop.

I went through the same thing I never could get the realy nice colors so I switched over toa full zeovit system and in 6 weeks my tank has chaned so so so much.Every one of my corals got color to them that I didn't even now they had. Imo amino acids without full zeovit gave me a huge alge bloom.

Well, after some more time and trying to keep ALK more stable I am fairly certain it was a voltage leak issue. After a bit of reading at RC I figured less than one volt shouldn't be a problem as many people seemed to have several volts with no ill effects. While my multimeter only showed less than one volt I don't think it was reading correctly. The other day I put my hand in the tank with a cut on my finger and felt a strong buzz in the cut. So there was obviously more voltage then I read. So a new heater and a ground probe later no more buzzing in the cut and some positive signs in the corals. The zoas seem to be opening a bit more where before they were melting and the sps that was in serious decline is now showing a bit of PE for the first time in weeks.
So it looks like voltage was the problem. Something to think about for those having issues with no other obvious water quality issues etc.
