Review on 🔵 AquaClear 50-Gallon Ammonia Remover - 3 Pack by Rebecca Porter

It turned the water green-brown when rinsed before use. For about 7/10 days my fish were distressed (all stayed in the top corner). After a partial water change, they feel better and the next morning they are in trouble again. I lost about 6 fish before it occurred to me that maybe it's the filter pellets that are so different from the previous ones I've used. I changed that and also did a partial water change. Since then everything is fine.
