What did you use to remineralize, to get a TDS of 5 @ 150. Also I would just do small water changes with RO water remineralized higher and slowly raise it. GH of 6-7 is even fine for them
I used Bee Shrimp Mineral GH+, http://www.saltyshrimp.de/english/be...l_gh_plus.html
raise kh to 4-5ppm
Everywhere I've looked people recommend a KH of 0-1. Do you keep yours in kh 4-5?
