The positive points:
- In 12 hours, the white water has become clear, the bad odor disappeared, excrement snails were totally absorbed.
- The rejection is done by micro-jets scattered along one arm, avoiding too flowage in small containers that may frighten the fauna and flora uproot. If you put above the water level, bubble effect (but bad for plants).
- Totally silent pump is the quietest of the many I've experienced.
- The filter cartridge is seen in transparency, which ultimately is not bad because it has an immediate view of its effectiveness and retention of dirt can best be seen if he should rinse or change it.
The negative points:
- The price with pump almost twice more expensive than competing for nano. Refills are also very expensive.
- The size, which is not nano (plan to have a well planted tank to cover).
- Everything must remove the tank for maintenance (unlike other filters where the cartridge is changed by the above).
