Review on Resun FBF-1000

Observation and Conclusion

Pros:
For $27 - This Resun FBF-1000 is certainly a good buy and does perform as good as the other vendor FR. Even though factoring in the cost for the Eheim Compact 600 and Eheim hose, it is still way below those of local DIY customized and other makes.

Cons:
Instead of using hard rubber for both the inlet/outlet housing, PVC piping with a check valve would be a good replacement and make this product a plus against the competition.

Conclusion
IMO, without adding the modification kit to raise the air-circulation level, the FBF would be comfortable with a 600 L/H flowrate pump and still able to see the phosphate media "dancing".

Likewise, you can still see the media "dancing" after adding the mod kit. But a word of caution is to turn to the lowest level from a 600 L/H pump otherwise you will have alot of phosphate media in your tank or sump. Alternatively use a 300 L/H flowrate pump instead.

Certainly a good buy for me as the total cost is only $73 inclusive of the Eheim pump, Eheim hose and Eheim hose converter.
