You’re welcome.

Happy Reefing!

Success! I ended up adding 1.8 grams of sodium hydroxide. 0.9 grams didn’t dissolve it completely.
Now I have vanadium supplement for life for $40. I’ll be giving about 80% of the vanadium pentoxide and sodium hydroxide powder away to my local fellow reefers.

@Randy Holmes-Farley May I ask: If I dilute above solution into RODI water, 20mL diluting to make 1000mL liquid, will the pH increase and cause the Vanadium to precipitate back.

Thank you.

I cannot be sure. I'd just try it.
