I use RO water, and I remineralise using JBL Aquadur.
I typically remineralise to a KH of 4. After dosing with EI, TDS ends up in the 300s.
Should my TDS be lower? If so, that would mean using less Aquadur, which has two drawbacks. Lower KH means pH swings are more likely, and more acidic water means my Nerite snails will not be happy.
So, what is the lowest "safe" KH for a Co2 enriched tank, and how do I make sure my Nerites stay happy in soft water...
