Depends... could be good... is this going into a FO
or Reef? If going into a FO
, then you're fine... but anything else would be a waste of money IMO
. All that basically is is an acrylic box with bioballs. Better off buying a 10 gal
tank at the LFS
for $10. This is because bio balls aren't needed in a FOWLR
or Reef setup if you have 1.5-2 pounds per gallon of LR
in your tank. Bioballs are suspected to gather nitrates.
This would be good if you had a FO
setup where you needed the extra biological filtration that bioballs can provide.
