This really helped with the water in our fish tank! Our fish kept dying and we couldn't figure out what was going wrong.. We went to PetSmart (I recommend going there for pet needs!)and talked to their aquarium associate and he told us to take in a sample.. After that he gave us this and it worked well and helped keep the PH levels more normal which helped the fish!! Great value!

Great product, that does what it says.
Good choice for use in soft water aquariums that are decorated with silk or plastic plants to maintain the proper PH for a soft water aquarium.
This product may be good for an indoor application into drywall studs but I wanted them for outdoor use on a cement wall. The mounting brackets are plastic and the very first one we tried to install cracked in half. It's a shame because the actual rack is a good shape and seems sturdy but plastic mounts are just not strong enough.
Received fast. Good item, but the plastic wall mount are no good. Had to hack with PVC metal wall mount and masonry screws. But the rest is OK.
Keeps the PH at 7.0, and good value for money. It comes in powder form and the 9ml scoop treats 10 gallons / 38 L. For smaller volumes during water changes I use a 1ml measuring spoon.
That liquid works really quickly and is easy to use
i use this product to keep the ph of my freshwater tank stable. API is a leader in products for aquarium care.
It does what it says; corrects the PH of very hard water to more in the neutral band
