I mean, in theory I could, but I've already got almost 400G of fish tanks in the house, and I'm changing out about 100g per week. It would get too pricey for my taste, and too much effort.You could try mixing RO/DI with tap? That way, you don't have to go full RO/DI and it will reduce levels of minerals that go into the tank. Although, you may need a remineralizer.
I started wondering about it after I contacted our municipality regarding some PFC issues they've had in the area. The response let me know that our watershed was fine, and they then included a water quality report as part of that response. I was reading the water quality report (because it's fascinating stuff, right!) and noted the levels for copper.Have you tested your water?
I understand the concern as we have copper piping. I test it once a year or so just to see if there is any copper to be found and there hasn't been any as of yet.
You're right I misread the chart. I'm guessing that the caridina shrimp were all lumped together under crystal parameters and really it's the only number I could find.If I'm reading the image correctly, copper levels are .183, which is fine for most shrimp.
And that's an interesting calculator as if the "latest" water quality report in my area is correct, then the amanos here should be dead, as per that calculator. They seem even hardier than cherry shrimp.
