Hi guys

Just decided to upgrade my Nano to a 90 Gallon with a 50 Gallon Sump. I've got 100 pound of dry base rock, around 150 pound of sand (I'll be able to put some sand in the refugarium area of the Sump)

Now couple things I have not decided onto yet the return pump....MAG (MAG 7) or Eheim (Eheim Compact+ 3000 Pump or a Eheim 1260 Pump) Not sure here what to use.

Same with the skimmer....and does the skimmer need a second pump to ? or does some have it included ?

Finally the heater how big and what brand or model ?
