The tannin tint is what I wanted for my betta tank, but this keeps the glass crystal clear instead of tea-colored. My fish seems calmer within a day, and it’s way easier than boiling whole leaves.

I was worried about losing the natural look of blackwater, but this liquid version gives me all those active ingredients without the murky tint. My bettas are much more active since I started using it.

The water stays crystal clear even after a full week, which is exactly what I wanted since I hate the tannin-stained look. My tetras seem more relaxed and their fins are fully extended since I started dosing this.
