That's good to know. I bought a box that has 200 gallons worth so I don't have the funds currently to fork out 60 bucks. What do you guys use?
Also, just wanted to say I have only been dosing for 3 weeks. My tank was losing a battle with hair algae and the vodka actually helped a million times over. My dose is only .3 ml, and I might continually ween it down but I've researched it a lot.
My refractometer was calibrated yesterday when I had checked. I'll do another water change soon, and top off with more salt water instead of RO so I don't dilute it down.
