I have a TDS meter and I have 2 different Hardness tests but isent conductivity a different test all together? What kinda conductivity are we looking for here? Sorry for the Noob question but I learn more and more every day!
the conductivity is affected by the TDS(organic and inorganic)
"solids such as chloride, nitrate, sulfate, and phosphate anions ( negative charge) or sodium, magnesium, calcium, iron, and aluminum cations(+charge)"
if your tds is higher ..the easiest way to reduce it is filter..(RO/DI)
you can mix the filtered with source water.
I know breeders that use RO/DI and then buffer it back for their Discus.
I guess thee is no magic # here? It seems like this is all sorta a feal it out as ya go thing. I like to have a target to work toward. When ya say try to keep it low = what does that mean to you? 50 or 250 or 500????? I think I am getting a head ake! LOL
Our local water co. uses Hach tests for free chlorine and total chlorine...quite expensive test kits. I use prime and haven't had any issues with it in about a decade of use. I know chemists who use sodium thiosulfate (Zip drops) which eliminates chlorine but leaves ammonia behind from the chloramine. They say their biofilter handles the ammonia with no problem.
Like Ryan and the others said, don't stress too much over the water unless it's too nasty to drink. I've always kept discus in local tap water. My wild RSGs live in it.
That male has lived in tap for the last year and he's a happy, healthy discus.
That is a Butifull fish! I think I may start using Prime. I saw it at the LFS yesterday. My Tap water is sorta a light TAN looking color. The water out of my RO unit is crystal Blue. I think I am gona miss that for sure! Not sure how the fish will feel about it. Thanks, Arkangel77
