Can Kent RO right be measured with liquid test kits?
I have been using the normally diy seachem GH booster to raise my RO water's gh from 0GH to 5GH, but wasn't liking how long it took to dissolve an read its not the best for shrimp.
So today while I was at the LFS I picked up some Kent RO right, the direction use a chart based on soft, med, an hard water... needless to say its not the most accurate thing I've ever seen, but when I try to test the GH of my "5gal test bucket" using an API test kit I can't get a reading.
After about 15grams(1.5tsp) of RO right to 5 gallons of water my water has gone from 80tds to 800 an still turns green with 1 drop. Has anyone else used RO right? Could use measure the GH or did you just go by the chart?
Any feed back would be great, thanks.
