Yes it is but I just took my time and bought things as money allowed. My system has been up and running 3 months but I researched and bought components over a 6 month period.
Bunch of nice tanks for sale in marketplace. If 210 works reefs4life has one up, also a few 125's as well
Injuring used can be risky but so many people on here take such good care of the tanks it makes it possible and affordable. With bigger tank comes need for more equip so this usually helps speed things up
