Looks really good i have not tried it because i dont have shrimp but am sure it works great i will just gift it to a friend because i have no need for it but has great review on the item so i recommend

I used this in my turtle tank to add a large amount of water in a short time. A few drops did the trick and while I didn't check it with a chemistry set or anything, the balance in the tank was not upset when I added the water. Normally if I add in chlorinated water it wrecks the bacteria in the filter and then I have to rehab all the water for a few weeks. I used a few drops of this when I added five gallons to his tank and the water and bacteria remained stable.

I have been using this for my large goldfish tank when doing water changes or topping up evaporated water. Works great and no issues. I would snag a larger bottle in the future juat because my tank is so large, but it doesnt require a lot per gallon. I always prefer those that go by drops rather than cap fills and this does that. I feel it lasts longer.
