Akadama in Shrimp Tank

[Mark Webb]

I want to replace existing substrate in my shrimp tank for Akadama. Are there any potential chemistry issues that may arise if I introduce the shrimp immediately. I will be running the matured cannister filter with the new substrate.

It will crash your kh to 0 for few weeks, then will stabilize. No other issues i guess.

Thanks. Is a high kh a problem? I have added Sera mineraliser and kh has gone up to 7.
