hanna alk

Hi all, I have a 20g tank with more than 15 heads of torches. I know my Alk could go down quite a bit on a daily basis even when I was dosing AFR or Kalk. I ran out of Hanna Alk reagent so I just bought a new bottle. For the last three days, I stopped dosing (everything not just AFR or Kalk)...

Came with a system I purchased that was taken down. 2 carbon doses, 1 regulator, NO POWER SUPPLY came with them I am unable to test. Nearly full large jar of All-For-Reef 2 small Modular marine overflow boxes 2 Hanna Ph Checkers Hanna ALK checker Everything pictured as is $100 shipped for all.

Starting a remodel and need to sell some equipment that I no longer need. I’ll post pictures in the next few days. Pick up in the SF bay area or shipped at the buyer's expense. DM me with any questions. Thanks, Eric

Hey, Im just wondering does anyone know how the Hanna Alk checker work? Chemically? As I understand it alkalinity is the tolerance to the change in pH, but the hanna checker only reads the spectrum from control seawater (no regent added) and the final one after the reagent are already added. So...

So I just got a new pack of Tropic Marin classic salt. Its dKH is supposed to be 9-10 dKH, but when I mix it up it comes out to be 14 dKH!!!?!. I mixed and tossed that bag around when I first got it. Ive made two batches with the same results. I measured and used the correct salt portions: ½...
