THe RO/DI unit is coming. I have read conflicting information about RO/DI units lowering the ph.
It some cases it says it did lower them and others that it did not.
There is no conflict about what I'm going to say, use RO if yuo want to bred the shrimp.
Stop worrying about pH, start worrying about what specific salts or total salts are in the water.
CO2 will not change that, but.....CO2 will change the pH, we can see this has no impact on fish/shrimps etc everytime we do a water chaneg with tap water in the CO2 enriched tank.
The only reason why softer water would not lower the pH, is if there was some other buffer being added they overlooked or did not consider.
If you remove a buffer, the pH should go down along with the pH.
Still, way too much obsession with pH here for breeding, fish health/shock etc.
Look at TDS, KH etc instead, it'll be more fruitful.
That + good feeding/foods will address most every breeding issue if you have enough breeding age individuals in a nice habitat.
