Saltwater aquarium setup: What's the minimum you need?

[revhtree]

We love to go overboard with our tanks...but we don't have to!

If someone asked you today to help them set up a saltwater aquarium and they just wanted the minimum, what would you tell them?

What do you think is the minimum equipment and drygoods needed to set up a saltwater aquarium?

That's a tough question. Because depended on your goals the equipment is going to vary greatly.
If doing just fish id say
Tank, rock, sand, salt mix, heater, a basic aquarium light and hang on back filter (or aio tank)
If soft corals id say the same but add RO/DI system and reef specific light and a sump if not an aio.
If sps and LPS the list just keeps going lol

First thing needed is a plan with a complete understanding of how a reef tank functions.
While researching you will get to know what each piece of equipment does and whether its a good fit for you.
Comming here for questions is fantastic but without a good understanding of how a system functions you will get confused with all the different ways/answers you get, imo.

This sums it up perfectly

I don’t think there is a minimum, just like there is no maximum. Some Reefers have coral in a vase, some have thousands of gallons. It depends on the goals, budget, and lifestyle of the potential Reefer in question.

• Tank
• Salt
• Water source
• water movement device
• heater (unless you keep your room temp around 78 degrees)
• fish + food
• light (optional in reality if you only have fish)

This is actually a tough question and will come down to what each individual reefer's priorities are.

Of course, you need a tank. But you could even ask, "What kind of tank?" depending on the 'why' in why someone has decided to jump in.

I think the question is too vague to answer as it is written. I would definitely need more info. Tank size and desired livestock have a pretty significant influence on the proper equipment choices, but I guess the absolute minimum for anything would be a vessel that doesn't leak, saltwater and food.

It's kinda like simply asking "what vehicle should I buy"?
I don't know. What's your intended use? Commuting? Racing? Taking the kids to school? Towing a 5th wheel?

 

[Gumbies R Us]

It depends on the needs of the person, what they want in the tank, and whether there will be enough for future additions.

If you live next to the ocean all you need is a tank and a circulation pump.
Assuming you could keep the tank in a good climate for what you're keeping and they were nonphotosynthetic animals.

I am assuming bare minimum here. I am a less is more person by nature and here are 2 of my most basic reefs.

The 1st is a 1 gallon jar that I bought at target. It had a small amount of live rock, an open airline tube and whisper air pump and salt water. I kept the jar near a south facing window and did 100% water changes 1-2Xs a week. It had a shrimp and pom pom crab. Eventually I bought a cheap LED light for it.

The 2nd was a 5 and a half gallon aquarium that I partitioned off an area at one side to make compartments for an AIO. I bought a small Rio pump for a return. Again I used the cheap LED, live rock and 1 gallon water changes to replenish trace minerals and keep nutrients in check.

In both dry rock could be used to save $.
