Michael Gray –
I’ve been using Aquaforest Kalium for three months in my SPS coral tank. My corals have shown better colour intensity, especially in the pink and red hues. The 50ml size is convenient for small to medium tanks. I test potassium weekly and adjust dosing accordingly. It’s a reliable supplement.

The product arrived quickly and the bottle is easy to handle. I added it every two weeks based on my test results. My soft corals seem more vibrant, and I notice a noticeable improvement in coral health. A solid choice for reef keepers.

I run a mixed reef system with zeolite filtration. Potassium levels were fluctuating before I started using Aquaforest Kalium. Since adding it regularly, the water stability has improved and my SPS corals have developed richer colours. Highly recommended.
