Benefits of a 90 gallon vs 75 gallon saltwater

What are some benefits of have a 90 gallon vs a 75 gallon saltwater tank.
Besides that its bigger.

 

more volume means more chemical to alter the balance. more volume means more fish, etc. it also means more lighting, space, heavier skimmer, more rock, sand, and bigger water changes

 

Larger footprint allows more room for aquascaping, and in general looks nicer. The tank is obviously larger, but it allows more room for fish as well.

 

More money!

 

Go for 120. But yeah if you going for 48"L max then go for 90g. That head room could be for fish that like to be on top. Looking at my 75g now that I converted into a Russian Turtle tank and it kind of looks small vs the 90g that I seen today at lfs.

 

Footprint is the same for 75 and 95 isn't it? One thing I noticed from my 90 to my friends 75 is that its easier to work in a 75 due to only being 18in tall compared to the 24in of my tank. If your main concern is water volume get a bigger sump. Im not saying I would trade my 90 for a 75, I like the all the space. But a 75 is easier to work in then a 90.

 

KLstokes hows that 10gallon with 5 clowns 3chromis and 2 damsels doing???

i afraid of what you would do with a 75/90g...

 

Volume for chemical balance, swimming room, more livestock, and because of the way the standard 90 gallon tank is there more depth for cooler aquascaping but definitely more $$ with everything including filtration, skimmer, pumps etc

 

More water volume and more vertical space for coral to grow or for fish to swim over rocks etc, it allows you to put a deep sand bed in and still have the same space as a 75 basically.
It's more difficult to reach the bottom, you may need stronger lights to reach the bottom, you can't really keep fish that are any larger because the footprint is the same but you can maybe add another small fish or two due to the greater water volume. It will take more electricity to run, you'll need more supplements for the greater volume.

Just a couple things I thought up quickly.

 

15 gallons.

There is not going to be much cost difference between a 75 and a 90. You will have all the same equipment, just a little more sand rock and livestock.
