Spialz Posted March 3, 2015 Report Share Posted March 3, 2015 I was playing around today to find the right amount of SS gH/kH+ to add to RO water to achieve the water parameters I was looking for in my Neo tanks. I wanted to share my results here in case anyone else was in the same boat. I used 1 gallon containers filled with RO water. I then added the amount of SS gH/kH+, shook the container to dissolve the salts, and tested for gH, kH, and TDS. These were my results. ~1ml (first line on the scoop) into 1 gal RO water: gH: 4 kH: 2 TDS: 104 This one was a little too low for me. I was shooting for a TDS of about 200 so I tried again... ~2ml (second line on the scoop) into 1 gal RO water. I figured double the salt = double the TDS. Well... gH: 11 kH: 5 TDS: 263 That overshot it a bit. So i split the difference... ~1.5ml ( in between the first and second line...although probably a hair closer to the first based on the results) into 1 gal RO gH: 7 kH: 3 TDS: 190 That's close enough for me and that's the ratio Ill be using for my water changes for my Neos. Its not all that scientific and I know a lot of people on here keep Caridina shrimp. As such, I'm sure they use gH+ instead of gH/kH+ so I don't know how useful this info will be, but hey...here it is. Hope it helps someone.

WaterBugg Posted March 4, 2015 Report Share Posted March 4, 2015 Is ssgh/kh+ better for neos than just gh+ Quote Link to comment Share on other sites More sharing options...
Spialz Posted March 4, 2015 Author Report Share Posted March 4, 2015 That's what I've read but I've never known exactly why that is. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted March 4, 2015 Report Share Posted March 4, 2015 The kh is to keep the water more stable from ph swings. I use gh+ myself and never had a problem. Just depends on your preference. Quote Link to comment Share on other sites More sharing options...
