Are nano tanks harder to keep?

I'm new to salt water tanks. I know with fresh water tanks small tanks are harder to keep than the bigger tanks. Is this true with sw? What is the best size tank for sw?

you are correct fishdude...and nano SW is even more difficult than nano FW because the water quality must be higher for the health of the organisms you keep...not to mention there are simply more variables

to further make things a mess, if you want to do a nano reef the lights really play havoc on temperature and evaporation

an ideal starter size (imo) is between 40 and 75 US gallons...a 55 is always a good choice because they are cheap (relatively) and a lot of different equipment is available for them

but, your best bet is to get a few good books. i would reccomend checking out the general SW stickys for more information

I would go with a bigger tank if you can afford it. More room for fish and corals...however nanos will light up a small corner of the kitchen or end table.

nanos are harder to maintain balanced water paramenters because there is less water volume in your tank. Rememeber that they are usually around 10 gallons. If you are just starting out, i would recommend a larger tank if its possible for you. Because when there are changes in the water parameters, they take a lot longer to develor because there is more water.

Just to be difficult...

I'm going to say the opposite :)

My 2.5g nano is actually my least maintenance intensive tank I own. Maintenance, is weekly to scrape the coraline off the glass, daily feedings, and every 5 days I refill the 2L for the auto top-off. Oh - and I have to remove the salt creep weekly or whenever it annoys me.

Anytime I do have a problem with pH, alk etc - a simple 2-4L water change solves the problem. (25-50%) A big reef tank can require what 30-40g of prepped salt water to do the same - I have a 2L pepsi bottle of prepped water sitting on my bookshelf "just in case". In some ways being small helps.

Once my corals really start growing - yes I could be fragging weekly... I can't keep much in there (2 hermits, a nassarius snail, and a red headed goby is pretty much my limit (though I like to push those - so I'm going to add a sexy shrimp or two when the LFS brings them in)).

I will say however I spent a good 6 months researching and designing the system... You can't just throw something together and expect it to be quite that maintenance free...

back to your earlier question right now i have a 5.5 gal nano sw tank and i haven't had to add a drop of water to it in two weeks...it just isn't evaporating..at all, or the amount is very minimial and my salinty has stayed constant for two weeks as well, so for me thus far very little matienence is necessary. i have a tiny whisper power filter on the back to help the LR with mainting a clean tank and this also helps create a suffient current for my tank. my heater is over sized just the way i like it and does a suberb job at keeping my water at a baumy 77 F. So Idk if this helps you at all but for me very little trouble so far but I'm looking to add some shrimp and other animals soon so I'll let you know then.

LIke i said for me Maintenece is realitivly easy maybe i'm the exception or I'm doing somethign wrong..lol

Nobody's gonna argue with me? Damn do I swing that much weight around here (OK NO FAT JOKES!)?

Ok, let me explain further my reasoning why a sub 10g nano might be better than a 50g SW tank for a newbie.

Firstly lets look at cost, I think my 2.5 with all the gadgets bells and whistles cost me less than a 50-55g tank and stand. That includes livestock and stand - thus if there was ever a major crash - honestly *ALL* I'd probably just dump the contents and start over. A major crash in a 50g tank - could result in needing to replace 500+$ alone in live rock.

Secondly, in a very small nano you notice all the little creatures. Not just the 'showpiece' fish. I can ID various copepod and amphipods now that I've owned this 2.5. Because those little critters cruising the sand become more noticeable in a tank this size - thus you're more likely to notice quickly when some parameter goes on the decline... With fewer things to look at you have fewer distractions - and have to pay more attention to what is in the tank.

You learn more about husbandry in a small tank, you're less worried about fiddling with the (non existant) skimmer etc or other hardware. More worried about overall condition of the tank - and you're quickly trained that the solution to every problem is a water change (And those water changes aren't going to set you back 30$ or more just in salt mix). Additives are little worry - cheaper and easier to do a water change than buy XYZ "Super duper reef chemical", a good habit to get into - I know many tanks that have crashed because some dummy added too much iodine, molybdenum, kalk, strontium the list goes on and on and on...

Because you're dealing with such a small volume of water, you tend to make sure you're getting the best test kits, a refractometer (hydrometers are hard to use in a tank as tall as the damn hydrometer). Setting yourself up for better success in the long run.

While the "Bigger is better" is probably a good motto for stores - since they get to sell you all the "Crap" you "Need" to keep your tank running, is it really true? Yes I can't exactly leave my tank unsupervised for a week at a time - which might not be a problem with a 180g tank, but who really needs that ability? And if they need that ability - should they really be getting into reefs?

Not really.

Personally I tihnk most people starting out will do much better with a 3 foot long tank simply because it's big enough for more than one fish, still forgiving, and not so big as to be ridiculously expensive.
A small tank for corals is not going to be 'cheap'. A costy light is still a costy light.

Personally I do need the facility to be able to leave my tank alone for 2 weeks at a time. It's called consulting work.

So, you could leave a 3 ft. long tank (I'm guessing that's 20 or 30 gallons) alone for 2 weeks?? How do you feed your fish??

Also, If I just get live rock and a few hermit crabs, do I need to feed the crabs? Or can they live off the live rock?

Thanks so much for your help.

Just to add to whats been said, although larger tanks are more expensive, they are better value for money as it is cheaper per gallon in terms of to set-up, run and maintain.

Yes, i agree with AndyL and S.Reef, that it can be done. I have started my first saltwater tank, a 12g reef and had few problems.

Dissadvantages include, more reading and research, more care, more time and effort, more limits on stock, harder to keep conditions stable and more money (per gallon).

Some of the advantages are, smaller maintenance jobs (but more regular), less overall cost, less space consuming.

But half the fun is that its challenging

i started in a twenty also, and honestly the 55 is more expensive with initial setup etc, after that maintenance costs arent really that dramatically different (though it does add up over the course of time of course)...but the 55 has been much more successful and much more enjoyable for me

salt mix and filters for your RO unit or RO water (depending on which way you go). replacing light bulbs periodically if you are growing corals and sich. power bill obviously goes up. some people dose various things (i dont). thats all that really comes to mind offhand
