Okay, I will keep this as short as possible.
Do not, I repeat, DO NOT use this product if you are keeping aquarium pet like crystal shrimp, Taiwan bee, Tiger bee or other fishes that are  sensitive to Ammonia.

Here is the story. Today, I am at the last day to complete cycling my tank, it is able to convert 4PPM Ammonia, Water tested NH3, NO2 0PPM, and my water was crystal clear.

My pH is 7.3, so I planned to use this product to lower my PH. I added a fist size amount into my filter with Filter Bag(I am so glad I did). My water clouded immediately...I did water test, NH3 0.125PPM, NO2 0.25PPM...okay, something is going very wrong. I did another 2 test after 2 and 4 hours. The pH lowered 0.2, but the NH3, NO2 remains.

I assuming is it the almond leaf I added, but I checked, they are not giving out anything harmful.

Then...I put some Peat Granules into a cup of water, about 1:3 ratio, I know the scale is completely off compare to a fist size to my 29 gallon. Then I do the water test, I swear to god, I never seen an Ammonia water kid turn green so fast! It turns to 8.0 PPM (max for API kid) in 1 sec. I am so glad I can pull them out before they can do more harm to my system.

I attach a photo, the water I used to mix with the peat is RO/DI water with 0 PPM. I never left any 1 star rating, this is my first.
If you are planning to use it on any aquarium pet like crystal shrimp, taiwan bee, I pray for the best luck for you.
