What is needed in starting a saltwater 'fish only' tank?

[sealife]

Thinking of trying a saltwater tank. Fish only. As I love fishkeeping. But it depends on how hard it is to maintain and what equipment is needed.
Is it like freshwater cichlids, where I just need a good canister filter with eheim or matrix media for the bacteria, a heater and air pump? Or is there more to it than that?

Also, I remember a store owner once told me I need to buy water from him everytime I do a water change. Is this true?

Also, which fish are great for fish only tanks? Is live rock hard to keep? What's its purpose?

As u can see, I'm clueless with saltwater tanks.

Thanks so much. Sorry for the noobish questions.

Yes you need ro/di water. Either bought or made at home with an ro/di system. Other things you need are salt, a refractometer to measure the salinity. Test kits to measure ammonia nitrates and nitrites. Power heads for water movement. Live rock and live sand are recommended. Caniater filters have been used but I think the majority of sw people will tell you not to use them. Obviously a heater is needed. Protein skimmer is optional for a fish only but recommended

In short answer it's more complicated

Live rock is not hard to keep all it does is provide a place for natural filtration bacteria to live

Thank you chbix for your response.

So pretty much, the equipment I need is:

- Filter: Sump ( with live rock as beneficial bacteria filter media. Does Matrix not work?)
- Heater : Any
- Power Head: Any
- Refractometer (Measure salinity): Which brand is more popular?
- Protein Skimmer: Any
- Test Kit: API test kit
- Ro/Di water
- Salt: which brand? Do I only add at every water change?

Is that pretty much everything I need?
- No air pump?
- Light is not essential?

Are water changes once a week like freshwater?
Also, what exactly is Ro/DI water?

Thank you again.

What size tank you thinking about? I started a 29 gallon tank! I spent around a grand for it. It can be expensive but if done right it can be less than what I spent.

I will give you a list to start a 29 gallon.

2 Nano Power heads.

Amazon.com: Hydor Koralia Nano 240 Aquarium Circulation Pump 240 GPH: Pet Supplies

1 Fluval 206 canister filter (this is where people will tell you different. Each have their own opinion. I am still using mine and have not had any issue. The key is to CLEAN the canister out every two to three weeks to avoid a nitrogen spike. If your just doing a Fish only, than you should be fine, but if doing a reef tank than you will need a sump filter.)

Amazon.com: Fluval 206 External Filter: Pet Supplies

I got this skimmer, it's very good for anything up to 75 gallons! Beyond that you will need a Bigger skimmer.

If your going smaller, I would suggest.

I got live sand, you can go with a cheap sand that is not live, but I would suggest live sand. Only because it helps with the cycle process and it speeds it up. Normal sand will become live over time, but buying a bag of it just speeds up the process. I got 60 pounds. I suggest a little less for you because my 60 pounds gave me a 3in sand bed in my 29 gallon. Maybe 40 pounds! Almost anything from this list will be good!

Amazon.com: Live Sand

Live rock! Now the same as sand, any rock you get will become live over time. I bought 50 pounds of Live rock from my LFS and it cost me around 250 dollars. My suggestion is not to get 50 pounds of live rock for a 29, as it over filled my tank and didn't leave a lot of swim space. The rule is normally one pound per gallon of fish tank. To be cheaper buy maybe 10 to 15 pounds of live rock and than a few pounds of base rock. The base rock will become live over time.

Base rock is not live! You can find it at your LFS. Here is a list from Amazon.
Amazon.com: aquarium base rock

Live rock is live and comes with some surprises! Because it's live and sometimes pulled right from the ocean.

Live Rock and Live Sand: Live Saltwater Aquarium Rock and Sand

More expensive, but well worth it sometimes. Most LFS with saltwater fish will carry live rock.

Of course you need the normal stuff, heater, temperature gauge, and so one.

When it comes to water changes, I would start out once a week with 10%. You don't need to buy your water from the LFS, all you need is Reverse Osmosis water. Nothing really special and a lot of grocery stores sell it as well. However, if your LFS is cheaper with the R/O water, I would buy it. You will also need salt to mix with the R/O water. A lot of people use this.

Important for salt mixing! Good luck! I will be back to help out when needed!

Lights are kind of self explanatory. It was apart of the bottom list. The list that said, plus all the normal stuff. Plus with a fowlr system you don't need the hundred dollar lights.

Thank u sooooooooooooooooo much for the info. It helped a lot.

if i offended ... I was only joking!
I am very very new to saltwater too and starting out very slowly with fowlr (hopefully):

Just something to consider...I am one who disagrees that RODI is a must for FOWLR tanks. For reef, absolutely, fish tend to be a little more forgiving than corals when it comes to water. I have used RO water and never had issues. RODI should have zero TDS (total dissolved solids). RO is usually very close. The extra 2-4 ppm you get with RO has never caused anything bad in my tanks. At $1.50 per gallon locally for RODI versus .25 for RO, I prefer RO.

Overall, saltwater is not that difficult to maintain. The startup is costly, but keeping things going is not all that involved. Asks questions here if you are ever confused, or unsure.

My words of wisdom...always remember that the folks at your LFS are there to make money. Advice from them can be questionable, at best, sometimes. Also, for buying fish, pay attention to the recommended tank sizes from places like liveaquaria.com. Many people put fish in tanks that are way too small and end up with health issues. They get frustrated and leave the hobby. Again, when in doubt, ask here. There is a lot of experience on these boards.

No offense taken! I was just pointing out that I said something. Didn't mean for you to think I was offended.

Good luck, with this hobby slow wins the race!
