Elos Alk test

[spawn]

I have done that with the old kit & it did test very high in drops, but in actuality it was probably right where it should've been. Also both kits tested the same, being 9 drops = 4.5dkh, so I would'nt be suspect of them, & I am very aware of how to use them. What besides maybe slower growth rates, would be likely signs of low alk in a tank?
