Hi all - trying something new in my 20L which I'd love to eventually add Amano shrimp to, but have failed. I am slowly transitioning the tank from post-water softer water (see above for the story for background) to bypassed water. I'll eventually test for copper too, but haven't yet.
There has been some debate above if the added sodium from water softener source water adds too much sodium. Based on my hardness levels pre-water softener from a bypassed tap, I am at 18dh (which is about 19 grains per gallon or 321ppm, so pretty hard). My water softener manufacturer has a chart published that shows 20 grains of hardness results in softened water containing just under 600mg of sodium, so I am more or less around there.
Is that too much for Amanos? If so, maybe the 600mg was the culprit all along. Once I water change this out (one 5g bucket per week), I'll remove all sodium from the tank.
I may even run a little internal Sicce filter with a carbon pad to clean it out further, but haven't decided. I treated the tank once 18 months ago with Expel P since I had a camallanus worm outbreak. But that was a long time ago, and you'd think I've water changed all of the meds out at this point, plus they breakdown over time. The meds worked great too and purchased from the Coop. Worms never returned.
