Default Substrate

For G Alexander - Is substrate a necessity? I planned for a bare bottom with high flow to prevent detritus accumulating.

Using a shallow sand bed does provide more space to host bacteria and it does have a positive impact to the systems biology. I would personally not use a bare bottom system but basically it is possible if you use good quality live rock additional.

How would you recommend I add substrate to the system?

1. Always use dry sand. It is not recommended to use the sand that has been accompanied.

2. Soak the sand in the ro water for a few days, change the ro water every day, do it several times until the phosphorus cannot be detected.

3. If you are willing to 1/4 or 1/3 each time

Sorry, it doesn't matter. You can say it here. You are right. Maybe I gave a bad suggestion. My experience is not very good. I am really sorry.

I would do as Jacky has recommended. Soak the material in RO water until it does not leach PO4 anymore. You can add the sand split to 2 or 3 weeks slowly. A depth of 3 – 4 cm usually works very well. I would recommend to use dry aragonite in the grain size of 2 – 4 mm.
