I came across a video made by a Japanese aquarist. XD I can't read Japanese so I used google translator and roughly translated it. The vid seem to claims that minimum water change and maintenance needed by using Akadama. It will keep the water crystal clear. It seem to said 1 year without water change and gravel cleaning every 3 months. Change the Akadama every 2 years. It stated after 5 days, the BB will grow in the Akadama pores and minimum cleaning of the soil is recommended as not to destroy the BB colony.



Akadama and aquasoil seem quite similar. Anyone can tell me the differences between the two and its performance/specification? Do Akadama contain ammonia?? @_@

Akadama vs Aquasoil??
