I’ve used this product for my new aquarium setup and it made the cycling process much easier. The dropper is very handy and I could control the amount precisely. No fish were needed, which was a relief. Ammonia levels stabilized quickly and the filter became active within a week.

It’s a reliable option for fishless cycling. The liquid form is much easier than using powders. I added it slowly and monitored the ammonia levels. The bacteria started working after a few days. Would recommend for beginners.
