Review on Resun FBF-1000

Got my hands on 2 units of the Resun FBF-1000 as I am deploying them for my "old" 6'x2'x2' tank to get rid of the unsightly look of RowaPhos n Chemi-Pure which are just dumped in the return chamber.

There are two models available:

FBF-500 for tank capacity below 500litres
FBF-1000 for tank capacity greater than 500lites

My first reaction of this the workmanship for the casing is value for money but disappointed with the instructions which was just a piece of paper. Well can't really complain for $27. Right?

To connection this FBF unit .. the following are required:

1) A small pump 600 L/H
2) Rubber Hosing size 16/22mm
3) Step-down hose converter 16/22mm to 12/16mm

Reason for item 3 is that most small pumps are having hose size of 12/16mm whereas the FBF-1000 inlet/outlet requires hoses size 16/22mm

Here is the pic of the FBF-1000:
