Ok, I thought all the KH tests were the same. That's good to know that they're not! I know my KH test is a different brand than my test kit but I used the chart in my test kit to see the results since my test didn't come with one. I will have to poke around on their website when I get home from work to see if I can find their chart. I believe the test is from Red Sea. Thanks for letting me know!What test do you use and what unit does it use for report the alkalinity? If it report mekv - 2.5 will be equal to 7 in KH. Ask your LFS about the alkalinity. I do not think that you have 2.5 in KH in a saltwater that comes from your LFS.
And welcome
Sincerely Lasse
