Ammonia in RODI Water (1 Viewer)

[WolfTangAquarist]

Something we wouldn’t expect from our filtration systems or even sourced from LFS.

Oceanlife has stopped selling water due to trace amounts of ammonia coming after filtration. We have had a few of our customers test theirs as well within that galleria area and it’s the same.

Just curious if anyone else has this problem or maybe don’t know they have this problem.

interesting. ammonium is removed by cation resin I believe. Wondering if its a problem with the DI resin (not enough, not packed well, etc.).

Reverse osmosis removes the hardness and decreases the pH, assuring that the ammonia exists in the ammonium ion state that is readily removed by standard cation (water softening) resin.

True when we run through our large DI resin filters it zeros out but it’s just really expensive. Let’s say all the filters are packed correctly and working, Is it possible that excess amounts could get through?

Is your source water hi in nitrates?

Or did it recently switch from chlorine to chloramines for sanitizing?

That’s a good question how would someone find out if the water treatment has changed?

Also side bar, anyone ever use GFO to remove silica from the water as it’s not ionic?

Contact your MUD or the municipality and ask I suppose.

Spectrapure makes a silica buster. But I think its a DI resin. Not sure on the GFO.
