i wanted to choose none for filtration and it came bak 150 dollars, and then air pump, had a number, i think it is quite a bit off, i would not use an airpump in ANY saltwater aquarium, NOR a filter
our 75 gallon with power heads, sand, lighting(pc),stand a emporer biow wheel filter(which we do not use, except to circulate) costs us almost 600$, ad to that a decent skimmer and you have a good tank, soem lr would also be a good idea, but could be added slowly later
and i agre the price for the oceanic is not bad, but make sure to check shipping or however you have to get it if you decide
