Setting 4ft CRS Tank

[bps11208]

Hi Guys,

Been playing with CRS for a month or 2 and is now setting up a 4ft tank to play with aqua scaping and breeding
Will be setting up the tank to be able to view from both side as i'm placing it as a dvider between the dinning room and living room

Will be using 3packet of red been soil and old sea mud powder during setup
The tank will be hook up with a chiller to maintain the temp at 24degree

Plan to place 2 big blog wood and x'mas moss, flame moss and nana in it
Will only stock up CRS after 2 to 3 week

Please kindly offer me advice as i'm very new to setting CRS
Should i use under gravel filter?

Thanks All for all the information provided in this forum and also thanks all in Advance for all the advice that's going to be offer to me
