Once I remember it smelling bad while still outputting zero TDS which baffles me. It's possible the smell is attributed to something that isn't detected by the TDS meter?  |
Just guessing, but odours are generally gaseous. TDS meters designed to detect solids, no? Ergo TDS (Total Dissolved
Solids) meter not able to detect gas? Have you been consuming a lot of Mexican food with plenty of beans the night before messing with your DI media? Sauerkraut or excessive garlic consumption?
As mentioned, I've not detected a foul odour from my DI media, nor experienced coral die off that I could possibly attribute to funky DI product water. Of course I've only opened the canister once in 4 years to replace it. Original media was colour changing & was already loaded in the cartridge out of the box on delivery. I saved it in a plastic container in the basement, opened & smelled it a minute ago. Still moist & absolutely no odour. Batch I replaced it with is non colour changing nuclear grade DI media ordered from Buckeye Field Supply (now Buckeye Hydro). If I were you I'd consider investigating alternate sources rather than those local fish stores, or at least question where they're getting it.
I understand there is a way to recharge exhausted DI media, but after looking into it & the caustic chemicals required to do so, I'm kind of ok with buying a fresh batch, particularly since the stuff is lasting me 3-4 years.
