Magnesium and calcium levels

[Metrontech]

So higher Calc is bad? Does it affect the lps etc?

Not bad per se, but not needed. Ca on a reef is about 380ish. That's all you NEED. We keep it a bit higher in tanks to account for any sudden drops that might happen, giving us some wiggle room. Aiming for 400-420 is fine and leaves you that room.
What salt are you using, and how did you get to 450?

I purchase pharmaceutical grade from a guy here in the city

Its pure calcium carbonate

Also using Reef Crystals with the MAG and CAL added

Just did a 15 GALLON water change, I will do my reg testing later

Thanks again

Reef Crystals on it's own is probably fine.

I was having issues getting Mag and calcium up with normal water changes

Which is why I went thus route

Since then I have beem able to keep them all up and level

Ph is good and phosphate is 0-.011

Just have to sit back and allow it to go

Tank is only 3.5 months old

I think for your needs, the salt is enough. What levels does it mix at?

[Metrontech]

Not sure what you mean by "my needs"

I'm slowly adding more and more lps Amd eventually sps

The salt really only gets me 300-350 cal and 1050 mag

Can never get it to be over those levels

I understood from everyone I spoke to that my Mag and calcium and alk had to be up and steady

What about using salinity instead?

Reef Crystals should mix much higher than that. Regular IO mixes near 270 or so on Ca.
Your "needs" are to keep Ca around 400, which RC should do fine without adding stuff. I don't personally care much what Mg numbers are, but no harm raising if you like. The alk you posted is fine.

What test kit gives RC salt Ca of 350? Doesn't sound right at all
