Then you shouldn't be surprised that your attitude gets a lot of unnecessary flack because of how your comments appear. If you can't be 'bothered' communicating effectively you contribute to a lot of reactivity that is unnecessary - but maybe you like confrontation?
Which is why modern taps have aerators built into them - helps mitigate the poisoning effect by removing some of the chlorine before we drink it.

@Jdejay02 - How would you get chloramines in an RO system? The RO operates by passing only water through the membrane so I am fairly sure it wouldn't be passing chloramines.

As for any hazard re Prime, the MSDS simply says to drink some water if you swallow it and wash it off if you have skin contact - I'd think that is because there is salt in the body and the reactivity with chlorine is considered a possibility. Given it dissipates from the system in 24 hours it would not appear to be a hazard if used as I use it (treat an IBC full of tap water a few days before it is used.

Seachem also say they have ample evidence from aquarium and aquaculture users to suggest it also, in 'overdose' levels, mitigates the effects of high nitrite levels, either by binding the nitrites in similar manner to how it binds ammonia, or by offgassing the Nitrogen component.

Believe it or not, having lost my fish to tap water, I did quite a bit of reading across the web before I bought Prime. I would not have bought it had I found ANY indication it might be either immediately hazardous or had long term consequences.

Actually I am more concerned about fluoride in the water than using Prime - as soon as possible all my top-ups will be from rain collection - unless anyone knows of an additive to remove fluoride? (RO to do it is a little expensive )

The discus I spoke of earlier got ammonia poisioning from the carbon in an RO/DI breaking the chloramine bond resulting in free ammonia in the tank. Catalytic carbon given at least 2 minutes of contact time will remove the ammonia in the water. It is used in most RO suppliers "chloramine buster" packages.

For chloramines I've always used vitamin c tables (aesorbic acid) at 500mg to 50 gallons of water. I dont remember my source so treat this like anything else you would read on the internet.

I crush the tabled and add it to the water, let me mix with an air stone. It seems to work pretty fast as in a couple of minutes but i know that's not scientific.

Never heard that one. I'm gonna do a bit more research. I want to use something besides my RO/DI so I don't burn up my filters near as fast. I can save the filters for my SW tanks. Thanks for the info.

first hit on google.

What special precautions do kidney dialysis patients have to take?
Chloramine, like chlorine, must be removed from the water before it can be used in kidney dialysis machines. Chloramines can be removed by adding ascorbic acid to the water or using a granular-activated carbon treatment.



Generally you would need to test your water to determine chloramine ppm to then calculate the required milligrams of aesorbic acid. I did that once and just settled on the 500mg per 50gallon rule of thumb. Considering that vitamin C is water soluble and even high doses are considered safe for people, I dont recalculate for every time or situation.

It's all been discussed before... over-looked... or ignored...
