Dumb Q - how do I test for chlorine? My screenshot above shows what I can test for - pH, Ammonia, Nitrite, Nitrate, GH, KH. Oh, I guess I bought a phosphate test too, when I started this thread. Do I need to buy a specific test for chlorine? Most test strips can test for chlorine, and the API master test kit Link to comment Share on other sites More sharing options...

Fish aren’t stupid, they would swim away. Think about any body of water and I bet the temperature varies significantly at various depths. I doubt any fish dies be cause they swam deeper and water temperature changed by 7 or 8 degrees. I'm definitely not trying to overthink it. Some people, very rare, have reported issues with it happening. I've seen it once. It's not something where I will say it's anyone's (or any product's) fault, but just a word of caution to try to add things diluted if you can or pour it to where it will disperse well. If you see a random death and that's something that was added in the timeframe... it's worth mentioning, so I did.

I don't have any chlorine tests. I'm going to chalk this up to my not adding Water Conditioner and will go back to doing so in the future, regardless of what type of water I'm using. I'm assuming there is no harm in using it, even if I don't need it. Link to comment Share on other sites More sharing options...

Doesn’t hurt and just another layer of security. 2 Link to comment Share on other sites More sharing options...
Rube_Goldfish Posted February 14 Share Posted February 14 From what I understand, dechlorinator uses up some amount of dissolved oxygen, but not enough to worry about it unless you're already on the edge of not enough oxygen and even then you'd probably have to overdose the dechlorinator. So under normal circumstances, yeah, it's probably harmless. Link to comment Share on other sites More sharing options...

Thanks for the confirm. 1 Link to comment Share on other sites More sharing options...
