Alk test kits
So recently got my Ca Reactor running and have been testing daily. Alk rock steady at 10dKH using a Salifert test kit (2015 expiry). Read that Salifert Alk kits test about 2dKH higher than Elos so I was quite happy running at 10dKH.
But I just wanted to be sure so a friend brought over his new Salifert Alk test kit. Guess what? His kit read 12.4dKH.
Hmm? Gonna buy an Elos kit tomorrow.
Anyone else experience this?
