What about shrimps. Do they need harder water as well?
I have caridina -shrimps in the same tank.

Black neon (what we call H. herbertaxelrodi in USA) and emperor tetras (N. palmeri) are some of the easiest-to-breed tetras, often with no intent or effort from the keeper!
If you want to check your meter add a very small amount of table salt to a litre of rain-water, the workings are in <"Help with my water....">.Hi all,
What kind of conductivity readings you guys get from rain water?
I got 3 µS. Is that even possible?
Hi all,
If you want to check your meter add a very small amount of table salt to a litre of rain-water, the workings are in <"Help with my water....">.
I usually get about 60µS, it can be over a hundred in the summer and I've had less than 30 µS in the winter after its snowed.
It is all limestone here and quite dusty.
If it has rained a lot lately (or you've had heavy thunderstorms?) it can be pretty low, and I've spoken to people in Scotland etc where they regularly get ~10microS.

Yes, I did. My R/O unit (a bit old membrane) produces water at 5µS/cm. After a week in my peat tank it has risen to 35µS/cm. My A. wolli are reproducing in a mix of 1:2 peat water to straight R/O. My Cristals are reproducing in 1:1 peat to R/O ... and my Wangenflecken in straight tap water (~80 µS/cm).
A grain of salt is ~0.5 milligram, so you added ~4 milligram NaCl.I tried salt.
Before 3µS
After 50µS
I placed 8 grains of table salt in 0,4 pt (pint) of rain water. What is the unit used in Uk on that small amounts of liquid?
Hi,
Would fishes get something useful in this peat treated water since it rises conductivity? In addition to humic substances.
Or will everything they need come from food?
Hi,Hi all,A grain of salt is ~0.5 milligram, so you added ~4 milligram NaCl.
A pint is 568 millilitre, so about 225ml, so call it about 20mg of salt in 1 litre of water. A 10 μS/cm rise in conductivity is equivalent to about 6.5 mg of NaCl per litre of water, so I think you can assume that your starting water really was below 5 microS conductivity.

Some people recommend letting the first few litres of water run away (you can get diverters that do this) or <"diverters with filters">, but I've never bothered.They installed new roof 2 years ago on our block of flats. And all new drainage. Could the roof leach something? Sheet metal roof. Should I wait before collecting rainwater? There´s no big factories in our town and were living in the middle of forests and lakes.
I think that is probably unlikely in mainland Europe, they tend to be a lot more careful with potentially toxic metals than we are in the UK (or I dare say you are in the USA).Sheet metal roofing may be galvanized with zinc.......
I do this, but I suspect the OP's rain-water is too soft.You could test the collected rainwater toxicity using Daphnia.
