Using a product like Akadama Soil lowers the pH of your aquarium and keeps it constant without having a severe effect on your KH, GH and TDS. This creates a much better and safer environment for your shrimp if you only change one water parameter and it keeps it there for as long as 3 years.
Akadama can also be used for Discus and many other fish that require a lower pH. The more Akadama you add the lower your pH will be. For neocaridina shrimp a 250ml cup of akadama should be enough to drop your pH as far 0.2 – 1 on the pH scale. For caridina shrimp a 2cm layer of substrate will be sufficient to give you a desired pH of between 6 and 7. It is important to always measure the pH a week after you have added substrate to your tank or aquarium.
One of the best things about akadama is that it’s a natural product and does not leach anything into the water.
It basically just changes your pH, making it by far the safest product to use. You do get other aquarium substrates that you can use, but akadama is by far the cheapest and safest option for any new or experienced person in the hobby.
