It lowers your PH. Im sure it does. kangshiang whats your PH? I can read Japanese. PH:7.8
TDS:250
GH:6
Im sure you are not breeding shrimp in that water, you must lower it somehow, please teach oblongshrimp, he has a 7.5 ph level. Im just telling you what it says on the box. It lowers the PH, and helps with taking color out of the water, and makes water clear. Takes out any bad crap in your water, and it help with micro organisms that are good for your water.
How to lower the PH?????????
OMG.......I am using the ADA amazonia soil as the substrate.
Please read the description how that soil work then you know how easily to lower the PH.
I have been breed CRS for 3 years and believe me even with PH 7.6 the CRS could breed without any problem.
I know you are in Japan...please contact with some famous CRS breeders there and ask them all those mineral rocks or black bamboo...are those stuff necessary to breed CRS????
I have been have contact those famous CRS breeders in Japan and Taiwan for years and that's the result we got.
Never mind...maybe those stuff are really work for you....
Cause the truth is everyone has different way to breed them....
One of my normal grade CRS tank. (PH6.5, ADA AS with undergravel system)
My only method of lowering ph is by using ADA AS and my ph out of the tap is around 7.8-8.0 and in my tank is around 7.4-7.6 right now. The tank is two gallons and I have succesfully bred Black Diamond Shrimp. I guess ph would be important for big breeders, but if you want a few to keep your shrimp from dying out and to sell a few maybe, then you could just keep your water as it is.
Please keep us updates Gabeszone :-D.
Same as what I did. (ADA AS)
Here is a picture (2.5 years ago.....with PH 7.6).......
Sorry for those ugly CRS.......:hihi:
