Using Prime with RODI?

[CStrickland]

Even without an extra chloramine can, a decent carbon block removes the chlorine portion no probs, and the di handles the resultant ammonia. But for someone living in a high chloramine use municipality, the chloramine busters are recommended by some manufacturers. Thus, a well-tuned rodi does not have trouble with chloramine.
We are not talking about making up for a deficiency in filtration by treating with Prime, we are talking about adding it to properly treated water for no reason whatsoever.

Ammonia is removed too, but I listed it separately because you said your well puts some in your water. Really, a rodis not a bad idea considering what has been found in groundwater. The tiny amount you get is probs less than the fish are peeing on the regular. It's not worth being scared of, or treating the water for.

I use it during TTM to make sure the ammonia concentration does not get too high in the three days they are in the tank.

Likewise. However that is the only situation where I use it.

I didn't want to assume anything about the rodi kit or quality of water in question. There are several variables to consider.

The OP states: "Reefers on my local forum are discussing the pros and cons of using Prime, even with RODI water. I'd like to hear what RC has to say.
Does anyone here routinely use Prime with their RODI water?"

I think that's what we are discussing and taking the possible variables into account.

I think that the consensus is that average tap or well water with a proper rodi kit does not need to be treated with Prime but it doesn't hurt to use it.

You have to be aware of your own post filtration parameters and decide from there.

I'd agree with that. It certainly doesn't hurt.

at what point does "can't hurt" become a waste of money. I spend enough money with this hobby without buying something that is really not needed.

Some people buy it to have it on hand in an emergency.

Good grief we're talking about a $10 bottle which will last a long time. Don't use it if you don't feel it's necessary but when you sink thousands, if not tens of thousands into this hobby worrying about a little bit of Prime is meaningless.

As I only use it for ttm of new fish, I find that the small amount used infrequently is at best a rounding error.

I think prime is great to have around just in case you have an emergency that spikes ammonia, or you need to use tap water in a pinch cause your kid poured gogurt in the tank so the stock has to move into a HT right away, and for qt too. Like keeping a polyfilter and some carbon around just in case. It's cheap too.
I doubt there's any cons to adding it unnecessarily, as long as you don't get a false sense of security and go lazy on changing the rodi filters. But I don't think "it can't hurt" is really a pro either.

I have a bottle left over from my fw days. keep it for emergency. that's different from using it all the time.
