Hi bro ThinkTank,
Apologise for the late reply.
Best Bio Soil is made in Japan, a natural black sand mixed with Zanesa Bacillus.
Decomposing organic matter such as manure, uneaten food, will be biodegraded by the bacteria, conditioning water and maintains it cleanly. For the amount to use:-
30cm tank, 1-1.5L (non-planted), 2-3L (planted)
45cm tank, 3-5L (non-planted), 6-9L (planted)
60cm tank, 4-6L (non-planted), 10-15L (planted)
90cm tank, 10-20L (non-planted), 25-35L (planted)
At the moment, you can find the soil in Clementi stores. More stores will be added over the next few weeks when our guys visit the rest of the LFS
Hope this helps!
