Is a saltwater tank harder to maintin than a freshwater tank?

My wife was asking me if it was much harder to maintain a saltwater tank than a freshwater tank. I had no clue what to tell her. The way I see it, it's hard enough to get the water parameters right in a freshwater tank... it must be even harder in saltwater...

What's involved in starting a saltwater tank?

To answer this question we need to know what you mean by "hard" or "difficult".

To me, "hard" and "difficult" are a reflection of physical labor. In this case, freshwater systems are much more difficult to care for, requiring frequent water changes to maintain the environment.

That being said, saltwater systems require a greater level of knowledge and learning prior to taking on the challenge. I don't consider this to be hard, but simply to be a process that takes time to acquire the knowledge and skills. After the knowledge is acquired and applied correctly, maintaining a marine system is relatively less time consuming.

For example, some people think it is easier to write a check from their checkbook that it is to use their banks online billpayer system. In fact, it is much quicker and easier to pay your bills online. It just takes time to learn how to use the system and get it set up properly. Once you do, paying your bills is much less time consuming than when writing checks, putting them in an envelope, licking a stamp, and driving to a mail box.

All right let me state the question a different way (complete neophyte here so bear with me):

How does the salt get in the tank? Is it special salt for saltwater tanks? Does it come in a pouch, liquid form, pellets?

Does the salt leave deposits on the tank? Equipment? Filters? Etc.? Does it ever harden and sink to the bottom of the tank in the sand/gravel?

I assume that water changes are needed... does the water being added need to match the salinity of the tank exactly or does it get adjusted once it is in the tank already?

How does the cycle work in a saltwater tank? Is there such a thing as a cycle? How long should one wait before adding fish?

I don't have a checkbook and bank online so I take it I'm halfway there already! :-D

You put the salt into the tank. It's synthetic salt that you mix to a specific Salinity or Specific Gravity (SG). It's a bag or you can buy it by the bucket. Since we are on the subject of water, i'm going to assume you have some experience with freshwater given the questions. The people of FW use declorinator for their water, but we in the SW world use, or should use, RO/Di, revers osmosis deionized, water. Much different from your De-chlorinated water. Yes Chlorine has been taken out, but so has lot of the Ammonia, Nitrates, Phosphates and dissolved solids that can be harmful to the inhabitants of the habitat. What inhabitants? Do your research.

Equipment... Skimmer, good water flow (pumps) and everything is based on what you will be keeping in the water (fish, corals and what type of corals). Sand and never gravel or crushed coral. Now, i do use aragonite, which is finely crushed coral, but it's sand like consistency. Why? Do research.

Salinity Changes when water evaporates. If you evaporate 1in in your 55g water the water may go from 1.025SG to 1.026. Sounds like a small amount, but if you are doing water changes to 1.025 and the water is continually being topped off with that amount of SG then your water will go from 1.025 to 1.030 fairly quickly and things in the ocean take a long time to change. What else changes? Do some research.

Cycle is a great thing. It takes a bit to get it started, can't say i've really learned anything about the FW cycle, but in saltwater it takes some time and you need to test your water while the cycle is going. What are you testing for and when can you add fish? Do research.

I stress doing research to get you acclimated into the world of SW. the questions have been asked several times and is available to anyone serious about the hobby. It's a pain in the but to maintain, IF you start it incorrectly.

For great information go to Reefkeeping Blog it's an online magazine and so is Reefscapes

Happy reefing!

All of those questions are knowledge questions. Knowledge which is easy to acquire, easy to remember, and readily available. If you do not find this process frustrating, and are patience and open to learning new things, then saltwater is for you. I would encourage you to lean on different sources of information, using each where practical.

You will want to begin with books, magazines, and by browsing the threads on this forum. I think you will find the "build" threads in the Pictures/Videos area to be the most helpful.

Another thing you should do is to to You Tube and watch a few videos on these basic concepts, such as how to mix saltwater. Many of these things are visually communicated much easier.

We can be a great source of knowledge and especially helpful in making equipment and livestock selections. You will want to lean heavily on conversations here on the forum for the ideas behind what purchases to make. Our only goal is to make you successful. We are not sales people and have no vested interest in one product vs another. It is very difficult to get unbiased advice in a book, magazine, or at the LFS.

I just stumbled across this thread and thought I'd add my 2 cents as an observer. My cousin kept Cichlids for 10 years before he decided to get into a salt water tank. Initially he converted his existing 90 gallon to salt and hated it. The daily or near daily maintenance was too much. His LFS convinced him bigger is easier in salt water so he stepped up to a 210g tank. The maintenance dropped to once a week.

Evaporation was the biggest issue. As noted in an earlier post, loosing 1 gallon in a 55g has a much greater impact than loosing 1g in 200g tank. The salt doesn't evaporate, but the water does. Other than the normal scraping to rid the front glass of coraline algae, his weekly maintenance was adding 5 gallons of RO water. It is far less maintenance than I do with my planted FW tanks, but it is a more fragile environment and much more expensive to replace if you kill everything off.

I'd say, if you're gonna do it, GO BIG!

This is a great post. I want to add that one reason people so often fail on the first "conversion" to saltwater is that they are not committed 100%. They get so concerned about money and they try to keep as much freshwater equipment as possible. In the real world, they should just start from scratch.

The best thing for you to do at this stage is to wonder around the internet (and specifically this forums build threads) to get an idea of what you want to try to archive with a marine tank. Saltwater tanks are so different to (most) freshwater tanks it is unreal.

Successful salt tanks tend to be set up as ecosystems, rather than a system dependent on the owner. This is one fundamental that you need to get your head around, coming from the freshwater world.

Interesting read. I have never even considered a SW tank. Well, I suppose I did and the answer was quickly NO. But after reading some of the info here it almost sounds like it could be right up my alley. Too bad I bought a canister filter already as I was going to go planted fw. My 55g is sitting on its stand waiting to be set up.

I think I will still do the fw tank in the 55g since I already have the filter and other stuff coming for it. But this sw stuff does give me something to look at and consider for a possible go in the future. I like learning and exploring new stuff and I can't get enough of researching something that I sink my teeth in to. Sw could very well be for me.

Thanks for all the info guys. I'm going to keep reading.

Having both a cichlid and a reef tank running currently I would definately say there is more physical work for my freshwater tank (50% wc once a week) but more on going little stuff for my reef.
I have no monthly schedule for my reef tank but here is what normally goes on for me.
2 5gal water changes a month.
Razorblade the glass twice a month.
Refill with RODI water every three days
Add some various trace elements for my coral when I think about it.
Empty the skimmer every two or three weeks or so.

Cost is much higher. Electric bills will rise, you need more water movement thus powerheads, new bulbs every 9-10 months ($130), elements and food.
Im a lazy reefer and try to do things the easiest way I can, which might not be the best route for you. There is no one absolutely correct way to run a saltwater tank.

That said, i love my saltwater tank and want to take down my cichlid tank in the next couple weeks to build a new saltwater tank(nixed my discus tank idea for anyone who was following that). I get bored too easy with FW, not enough to tinker with.
