Seachem 卡塔帕茶包

My betta is finally building a bubble nest after I started using these tea bags. The tannins turned the water a nice amber color, just like his natural habitat.

The tea bags dissolve slower than I expected, which is perfect since the tannins leach out gradually instead of dumping in all at once. My betta's fins look more vibrant after a week, and the water has that natural amber tint I was going for without turning cloudy.

My shrimp tank water finally has that warm amber tint I was after — the tannins leach out gradually over a couple days instead of dumping in all at once, which seems way gentler on the colony. The bags themselves are super convenient too, no messy boiling or straining like with loose leaves.
