Calcium to high?

Thats standard instant ocean
Are you mixing the box all at once?

Only about 5 gallon changes every three weeks so not the entire box at once

I have this issue as well but I use the reef crystals. My lfs told me to ease off the reef crystals for now since I have a low coral demand. I had a bloom of coroline then some turned white now seems to be coming back. Our tank is about 6 months old maybe 7.

Depends on what you added to raise them. If you added nothing, then no, I wouldn't conclude there's any relationship.

No I haven't had to add anything to get these high levels

I had quite a bit of red and green coroline algae on the back of my glass. But I scraped it off and is slowly coming back I don't mind the color

If you are not adding calcium or alkalinity, there's no need to even bother measuring magnesium. It will be whatever was in the salt mix, which generally should be adequate.

I discuss magnesium here:

Thanks for pointing me in the right direction., I couldn't figure out where to start my reading.

All too often people on the Internet are quick to try to make you look small and attempt to make themselves look better.

I let it grow on the back glass and keep the front clean. The sides I clean once and a while to keep it from getting too thick.

That's exactly what I have been doing

What are you using to measure your SG? If your device of off, i.e. mis/non calibrated it may be causing you to add too much salt mix and by extension too much Ca, Mg and alk as well.

That's a good point but I have two hydrometers and a third fluval one in the tank and a refractometer

I would likely rely more heavily on a refractometer if it has been calibrated with a solution that is close to the refractive index of the sample you will be testing, i.e. 35ppt. Like this:

It came with solution to calibrate it when I bought it. My refractometer works fine
