Tpshrimper Posted July 27, 2018 Report Share Posted July 27, 2018 Anyone with experience using blue wizard have proven gh/TDs math? As in what TDS gives you 1 degree of GH? I've found some old posts that say 150tds gives about 4.5 GH but looking for others input. I'm going to test out this weekend but figured I'd ask the community first! Thanks!

EricM Posted July 27, 2018 Report Share Posted July 27, 2018 ~25-30 TDS per GH is a rough number to go by. there is some variance with all GH minerals. just how it goes. Quote Link to comment Share on other sites More sharing options...
Maurice Posted August 23, 2018 Report Share Posted August 23, 2018 I remineralise to 135 tds and this gives me a Gh of 4.5 with blue wizard. A friend of mine gets exactly the same results use RO water with tds of 0 Tpshrimper 1 Quote Link to comment Share on other sites More sharing options...
