Ok, update and observations..
pH - 8.0
Mg - 1350ish
NO3 - non detectable
PO4 - 0.04
Ca - 450
Alk - 4.0
Ca and Alk are a touch high, but not enough to affect things and in fact are the values I used for years with great growth.
I notice that I have to clean precipitate from my pumps and power heads every 3 months. Any loose sand in my sump is solidified. Even my mesh bag with 1c of carbon had solidified.
Something is whacked with the chemistry in the tank, and not sure what.
Anyone have any experience with precipitation? I've added a small tray of sand to my sump to see if and how long it takes to solidify.
My previous sandbed turned into a slab of concrete that I removed in large sheets, some I couldn't even break up by hand.
WhenI ran a phosban reactor, even that media solidified.
Hate this freakin' tank!!
