Hello party people I'm running a Waterbox 60.2 approximately 50 gallons
I'm dosing All-For-Reef about 30ML day spread out between 15 doses in 24 hours. That being set I'm
Coming up on the upper limits of the uppermost dosage and this tank
Still has a lot of growing to do.

What do you mean the uppermost limit of dose?

If alk and calcium are not too high, you can increase the dose as much as needed to maintain alk. There is no practical limit.

Are nutrients out of line now?

My alk is 8.3, Cal 380, mag 1830 but I know all for reef has a max daily dose and I'm coming close to it.

You have 20 mils before you even reach the suggested limit, and some people have dosed double the max with no issues. You should be fine.

No it doesn’t. As Randy said there is no limit. I have a total volume of 65 gallons in my tank and I’m dosing 50ml daily in a very mixed tank. Your parameters look fine to me although the mag is a little high in my opinion. I dose AFR 0nce a day at at the time my light are fully ramped up in the morning. Been doing this for many years with great success
