Went crazy with the Alk. test kits today. Normally I'm sick of drops in vials at the end of the day, today I was motivated here you go...
Alk in my tank according to our precious test kits
API-> 9dKH (brand new)
Hagen-> 10dKH
SeaChem-> 6.7dKH
Salifert #1 -> 9dKH (one step type with orange/red tritrant)
Salifert #2 -> 7.4dKH (two step less than 6 mos. old)
Salifert #3 -> 6.7dKH (about one year old lives in my apt. with no light and stable temp, two step)
Here's the kicker, chem people help me out->
One step Alk test (Salifert w/ Salifert reference solution)
Salifert #1 -> 5.8dKH reference solution is supposed to be 7.0dKH
Strange huh? I kept hearing Flava Flav "You can't trust it" playing in the back of my mind.
