So I have been fighting Dino's for about a month now, and just finished my second 4 day lights out cycle. I have posted the ph, raised my Alk to 10, and performed many water changes/Dino siphons. I have been thinking about starting hydrogen peroxide dosing, but before I did I wanted to clarify a few things. I have been doing some reading here and a few other sources, and have always seen that 1ml per 10 gallons is the recommended dose. Should I dose based off the volume my tank can hold (38 gal) or what the actual water volume is after displacement (probably around 30 gal)? Has anyone ever had any bad experiences with hydrogen peroxide dosing?
