I’ve used this block in my 50L freshwater tank for two months. The algae levels dropped quickly and the water stayed clear. My fish seem more active and the tank looks much cleaner. Easy to use and no side effects on the fish.

The block dissolves slowly and works well over time. I added one block per 20L as recommended. After a week, the green film on the glass reduced noticeably. Good value for the price.
Jacob Berry –
My aquarium had a persistent algae problem. After using one block per 20L, the water clarity improved significantly. No fish stress or changes in behavior. It’s a simple and effective solution.
