just as described. cheap and lasts a while bc of how concentrated it is. it’s also safe to be overdosed in case of an accidental spill/over treatment.

Great for Plants!!!!!!
Why did you pick this product vs others?:Great stuff if you are a plant person!!! This is Great, and a little goes a long way, just 2 drops will change the water PH making it great for plants! No more brown leaves. If you have sensitive plants likes calathea, alocasia, anthurium.Â

For large tanks
We have a small 5 gallon tank and the smallest measurement on the cap is 20 gallons, so we have to eyeball a quarter of the tiny bit in the cap. Didnât notice a huge change in water quality
