Does anyone know if Conway city water has chloramine in it. Want to make sure I have the right RO/DI unit.
Conway corp dumps all their chemicals for the month in at once. So for one day a month you have some pretty bad water for tanks if you dont filter your new water. My TDS meter normally reads tap water at 30-40ppm, but during that one day a month it has hit 60-70 before. Yet my RO/DI unit can still handle it and spit out 0ppm water. I've tried to get them to tell me what day a month they do this but they will never tell me, and I only make water every once in a while so I've only seen this happen twice in the two years I've had a RO filter.
My TDS readings are consistently 4-5 ppm out of just my RO and consistently 0 after the DI. Does Chloramine constitute a dissolved solid? If I'm getting 0 TDS am I good to go?
From everything I have read in the last few years a TDS meter can not detect Chloramine. It only measures conductivity and since most dissolved solids are ionic the TDS meter can read the conductvity created by the free floating ions. There are a few things such as sugar that do not conduct so there for if you ran sugar water through a TDS meter it wouldn't register anything. Chloramine also does not conduct from what I understand which is why ever so often it's good to test the Chlorine levels in your tank. However RO/DI filters are designed to remove Chloramine from the water. So if your TDS meter is running a little high you can assume that Chloramine along with other trace elements are in your water, and when its reading 0 it would be safe to bet your water is safe. My Chemistry Teacher would be so proud that I remembered something from class haha
Thanks Wylon! Hope you guys don't get tired of all my newbie questions. I'm sure I'll be asking a lot of them.
There's a good video about chloramines and filters on the bulk reef supply website, not all ro/di filters take it out. Sent from John's Tapatalk
Thanks, I'll try to call the water dept. tomorrow. If they aren't any better than the waste management division is at answering questions it may be frustrating.
haha, I love questions because it forces me to remember things I haven't researched in years and if necessary do more research. Which is what this hobby is all about, learning something new every day
When I was having issues in Bryant, they were happy to tell me that they were not adding chloramines; my issue turned out to be a new water tank had been brought on line. That change destroyed almost all my corals in a very brief period of time. It has taken almost 9 months for my water to return to normal. Now in one of my tanks SPS seem to be thriving, however one of my tanks have not recovered and perhaps the rock and substrate will have to be replaced.
