Dosing vsRefugium

[Terry DeMott]

I want to go back to a refugium . I am using nopox and phos-e Should I use that up or just stop it . Also using all for reef Alk 9.6 ,cal 743, mag 1082 dosing 1 mil how do I reduce cal was dosing 3 mil but reduce it.

Do you know what your phosphate and nitrate levels are at? If they are very low and you want to go to a refugium I would stop nopox and then switch. Depending how much nopox you have left, you might want to use it up first then switch. Guess it also depends how soon you want that refugium to start too.

I'll let someone else chime in about the calcium problem, I am not sure how to help besides water changes!

If you got it might as well use it up unless you think it's causing you issues.

I'd overlap a little, backing off the carbon dosing when you add the fuge back, test often during that period.

So I'd basically taper or ramp down with the addition of chaeto being somewhere in the middle of that taper, testing often and really letting the tests dictate the ramp.

I’m in the process of doing this very thing. Just keep testing and dosing even once the refugium is up and running.

Wait on the refugium, and get your big 3 sorted out first.
Stop dosing completely. With mag that low, I can't help wonder if your testing results are bad, I don't think water can hold that much alk and calcium without the magnesium being a lot higher than the numbers you're showing.
