Here's another pict of my old 2 ft. Was still using under gravel. Know nuts about DSB, sump etc. Even had a heater in the tank . Office aircon too cold. At times water tempreture down to 24 degrees. Was using cannister filter and top up with mineral water daily.
Looking back was like dam blur man Don't even know about SRC. All thanks to Bros in SRC that I was able to embark to my current tank
