The tank was 48"L x 12"H x 20"W that's probably 60 gals?  However, I only
used 2 handfulls of straw.  Perhaps, that's why I never noticed a water
discolouration problem.   I did one water change at day 35 to catch out
some of the FFF or Florida Flag Fish (Jordanella floridae)  aka American
Flag Fish b/c there was so no algea for them to eat; I have no food and
they were turning on the  Rotala wallichii.
