Good Stuff !
I use API Stress Zyme to start new tanks and every time I do water changes. It really does prevent serious nitrate and ammonia problems in new tanks when used as directed.
This product is amazing for clearing water in my freshwater tank. Wish I had found it sooner.
best price ever
smaller sizes in stores cost more! wonderful product aswell, really helps with the gunk under the sand
Great Product for Aquariums
This Stress Zyme was delivered quickly to my front door. I was so glad because i ran out unexpectedly. Thankyou Chewy!
I use API Stress Zyme Freshwater in all of my 4 tanks after water changes! It helps maintain the good bacteria levels so the water remains clear. I highly recommend this product.
Great product.! I use it for starting a new aquarium. Chewy delivered quickly.
I use this once a week and it works great. Keeps water clear. Waste in gravel is broken down and waste in filter and medium is kept to a minimal.
Tried and true, as long as your properly cycle your tanks and just use this as a boost everything is great. I use it regularly and in the place of their quick start product (when setting up a new tank). Give it a try, it can't hurt!
Working so far my fish are still alive they are swimming and eating as normal as I think they should
Works good, keeps fish alive, tank stays cleaner, all around good product.
