What color is this General Hardness test?



Is it "Orange" or "Green"? It looks Orange to me, but Ive added 35 drops of solution to RO water with no noticable change! Im hoping it went right to this "Green" color after the first drop was added meaning I have 0 dGH. Can anyone who's used this test kit help me out here?

Would you consider telling us which test (manufacturer) it is?

Looks green to me. RO water should indeed turn green at the first drop of reagent. Have you tested your tap water in comparison?

Oh, I thought I had typed it into the post but I must have deleted it or something. Its an Aquarium Pharmaceuticals test kit.

I hope it's green. I will do a test of my tap water right now.

I just tested my tap water and I noticed a change from "Orange" to the same "green" color (as my RO test) at about 24-25 dGH. So Ive come to the conclusion that APharm's GH test kit sucks because the color change is WAY to subtle. Can any of you recomend a better one? Thanks for all your help.

Are you color blind? Seriously have you ever taken one of those tests? On my monitor the color is undoubtedly green. Is that glider yours?

I use the API GH kit also and there's not subtlety to the color change for me. It should start off as a clear orange that'll turn either fully green, or yellowish green depending on if you have a full or half GH level. For example, if my water is 17.5 dGH, on the 17th drop the liquid will turn yellow-green. The 18th will go full green.

Here's the difference between the orange and green of my API GH kit. I should note that the orange deepens as you get closer to the GH level then it'll turn yellw-green/green in an instant.

No, Im not colorblind, Im just having a hard time reading this particular test kit. When testing either my tap water (about 24.5 dGH) or my RO water (still unclear; about 0-4 dGH) the first 3-4 drops of reagent only affect the water's color very slightly (mostly clear with just a very light tint of color) then as I add more reagent, the color becomes more and more distinct. I definately am noticing the color change when testing my tap water, but the RO reading is still unclear. Im not frantic about it anymore though; as long as the dGH is lower than 10, I know my discus are safe. Thanks for all the help everyone.

Yes, that's my glider freeflyer

Here's the color difference between my tap water (left) and RO water (right) with one drop of reagent added to each.

Subtle difference, but RO definitely is a green tint versus the orange of the tap.

Thanks bharada, those pictures helped me out a lot. So, even though the green tint is very light, the RO water is still 0 dGH right?

Your first picture looks green to me. So I'd say around 0 GH for your RO water.

A better way to monitor your RO's performance is with a TDS meter.

haha, david, yours looks just like what I got with a bad/expired AP test kit, 35 drops, no change. Got another kit and it worked.
