Ultimately, when you get to your desired gh, you want to


  • take out and add the same amount each water change (ie. 10%-20%)


  • have the same gh in your new water to match your tank water's gh


  • Add pure only when topping off what evaporated because the gh and minerals are left behind. :)

It's cheap and works great,   Both KH and GH are at 0 fresh out of the unit and I remineralize with salty shrimp bee GH+.


I put mine on a 2 way valve off the hookup for my washing machine so that It's only used when I need RO for the shrimp tanks, and the waste water goes out the same pipe as my washing machine drainage.
