All I have is SPS so I thought I'd ask this here instead of the chemistry forum..
I was using lamotte ALK kit a couple weeks ago keeping my alk at 7.2. I ran out and ordered the refill kit. While I was waiting I was using an elos kit I had. It was saying 7.5. it said 7.5 everyday I tested till the till kit came in. Lamotte refill kit came in and read 6.4. So I'm like what the heck...I raised my alk back to 7 according to lamotte over a few days and frags lost what little polyp extension I've had. They just didn't look as good as before. I just kept is at 7.2-.5 for the week. Saturday I bought a redsea kit and tested to compare. It read 8.7 what the heck. I let my alk come down naturally the last 2 days and today is at 8.1 after reducing my doser the last 2 days. I don't even know what to think my freaking ALK is right now. BTW elos still reading 7.5 today [emoji23]
