GRRRrr, bad GH/KH kit

I ordered a GH KH test kit from Amazon. Just used it today and it's total nonsense. I tried each test several times with the same results. GH never turned color no matter how many drops I put it in, and KH turned colors with 1 drop.

Anyone else experienced this? Frustrating when trying to figure out c02 and dosing stuff.

Are there any GOOD test kits out there? API is unimpressive

API is ok if they're fresh. Still, I much prefer the Sera Aqua-Test kits overall, the GH and KH are very easy to use and read. Love the big vials as well since you can mix without capping the thing after every drop.

Here's a forum sponsor that carries them:

I had the exact same issue with my API GH/KH kits. "Glad" to know it's not just me, because I was thinking about getting new ones. I'll try another brand.

That's too bad, too, because the rest of their tests have all been very good, in my experience.
