20L CRS TANK, [KH]

This is my 20Gallon Long tank:

up 20L, low 10g



Started from Setp 08
TDS : 380~450
pH: 6.0-7.0

Substract : ADA Amazonia I
Filter : Tottoo pre-filter + 2225 (tottoo bio media), tom filter for UGF

This is the Totto prefilter on the left hanging on the left of the 20L
Picture from lucky-shrimp:http://www.lucky-shrimp-discuz.idv.tw/view...;extra=page%3D2

it force the water 100% go through inside media

my choice of media is following:http://www.lucky-shrimp-discuz.idv.tw/view...;extra=page%3D2
first 2 is wool filter for filter large particle in water.
last 2 is Totto bio media


Here is the filtration map of my 20L

red part is Totto pre filter (with out power ) pulled by a Eheim 2215 ( Main bio filtration )
blue part is the Under Gravel filter ( for small 20 H/10G ) so its size around 2/3 tank and powered by the Tom hanging filter at the back.
the UGF covered by a blue pad then over the substact.
More explanation of UGF from my blog: http://kh2crs.blogspot.com/2008/09/tank-mo...ndergravel.html

so this 20L is under 2 way filtrations:
1) totto +2215 for main filtration
2) tom filter + UGF
bad side of UGF is reducing the life of the ADA susbtract.
so I choose a small power Tom Canister filter for running the UGF
