JBL ProAquaTest Fe Iron & Refill

Finally, a test that shows the iron level clearly – no more squinting at confusing color charts. I used it on my freshwater tank and could tell exactly how much supplement to add. Seems reliable for both fresh and saltwater setups.

It gave me a clear reading in under 5 minutes, and the refill pack means I won’t have to reorder for months. My plants are finally looking greener since I started tracking the iron levels.

The test is so much simpler than the strips I was using before, and I love that it works for both fresh and saltwater. It gives me precise readings on the iron levels, which is exactly what I need for my planted tank.
