Can you add Prime to a reef tank???

[VA5]

Hello,
I had a rash of sudden coral die offs. Water chemistry was all within normal parameters with standard and Triton testing.
I later noticed my RODI system was not working with TDS of around 80 verified with a new meter.
All filters and membrane have been replaced (likely a defective membrane as it was not too old).
My question is can I and should I add prime directly to sump.
I have a system of 450 gallons and nothing currently seems to be dying.
TY for any advice

Yes, Prime is reef safe, I have put it in my tank many times. Always good to add things in the sump so some coral doesn't get a super concentrated dose.

What do you expect to “remove” from the water by adding Prime?

It doesn't sound like you have a good reason to add it, so I wouldn't.

This is the correct answer. We are meant to believe that we should buy “super duper bad stuff in a tank removiciver” when in reality we just need patience.

I assumed the OP was concerned that chlorine/chloramines had made it through a compromised RO membrane, and Prime would be a legit fix for that.

Though fish should be swimming around like their gills are on fire if you had that problem.
