They are all so lovely, seen your pics!
Blue Rams are very sensitive and require mature soft water. I have never kept gold or Bolivian, but it is a well known fact that the Bolivian ram is a more hardy fish.
Are you running an airstone.
No don't put the carbon back in it will remove the med.its new so its clean, i will put the tube in now... should i route it in the tank opposite of the filter? the other side of tank
and route it down to the gravel?
I would avoid it if you have an older style boiler with a tank in the attic as the water sits around for a while.I have no idea what kinda boiler we have, we do have a hot water tank though..... I always mix hot/cold water out of the tap and add it straight to the tank.
