hi this is my first attempt at saltwater! i have been keeping freshwater tanks for serveral years and the lack of diverse life, ie. invertibrates has lured me over to the salty side. so in addition to 7 freshwater tanks of various sizes i have started up a nano reef tank, to get a grasp on how marine tanks work. planning to make lots of mistakes along the way, as it seems like the only way i can learn things these days is the hard way. At least i have fairly sound knowlege of how aquariums work in general, and with copious amounts of reading i think i can apply this to a marine setup with some degree of success.

if it seems like i am explaining things in a detail that you probably dont care to know, please assume its for my own benefit! because it probably is :)

the current tank is a standard two footer, about 50 litres. this will be changed soon to a slightly larger, 2x18x18 tank.

for lighting i have a 2' fixture with 4 T5HO globes. filtration is currently via some old freshwater filters i had laying around, 2x fluval 4 plus. they are the internal cannister style filters with large sponges attached. i realise they are a bad choice for many reasons but for a temoray fix they arent too bad :) i will be getting the little vortech powerhead once everything is moved into the larger tank. and once i can afford it!!

i have no skimmer, no sump, no fuge. i have an old aquaclear 300 filter that i could turn into a hang on fuge, but im doubtful how effective this will be. a hang on skimmer is a definate possibility, but for now the wallet says NO

tank was filled on 01/05/2010 with NSW. placed a couple of pieces(0.5kg) of live rock from the LFS in the tank along with some substrate i commandeered from one of my freshwater tanks. i rinsed it REALLY well in case you were wondering. i threw in a cube of frozen food once a day for the next few days. probably not the best way to cycle a tank i admit, but you get that.

more live rock(1.5kg) was added and i started finding some amazing hitchhikers in my tank. bristle worms, brittle stars, feather dusters etc etc etc. this is what is missing from freshwater... a diverse ecosystem bursting with life! they all seemed to survive the initial ammonia spike which was nice. on 08/05/2010, the tests indicated no ammonia or nitrite, and nitrate at 10ppm. diatoms had begun to bloom at this stage. i added a small zoo colony to test if it would survive... heheh... so far so good.
more live rock(4kg) went in, this time i think it is uncured stuff, as it has all sorts of dying corals and things on it. so added more cured stuff(0.5kg) to perhaps assist in case of another cycle. i also added some random snails to help eat up the diatoms. so far they are doing a good job so im happy :) more snails are definately on the cards if the paramaters are holding nicely.

this is where i am at so far, waiting on my new tank to arrive so i can set that up and keep building up the cured liverock. once the tank is pretty stable i will be adding a box of uncured liverock into the tank. this is both exiting and scary since it will contain alot of life but will surely test the biological filtration i have been attempting to sustain. only time will tell tho ;)

so far the inhabitants that have unintentionally come in on the liverock include..
tons of filter feeding type things
several bristle worms
two brittle stars (small, brown and white)
a small crab (smooth body, hairy legs, green/brown coloured)
a WIERD small creature with six legs, that looked very 'chunky' for lack of a better term. it walks very slowly and purposefully!
lots of tiny pods (got to be a good sign)
several brain corals
two orange acropora corals that i hope will survive!
a strange coral that has small, stony, star shape tubes with masses of clear tentacles that fluoresce green! a bit worried about this one!

here is a FTS, please excuse the disgusting state of the tank... hehehe... the glass is so scratched i never bother to clean it!

Thanks for the sharing the pic. Sounds like you are getting a grasp of things. You probably know this already but you really want to keep you systems free and clean of debris. Power filters full of media are generally not something you want to have and if you do have them you want to keep the media cleaned out or replaced frequently.

For example, you could maintain that exact tank with a low bioload using a vortech (excellent choice BTW) and weekly water changes alone. Add a sump with a skimmer or just a HOB skimmer to that and you would have yourself the makings of a sweet SW tank.

Did you use gravel from your FW tanks? If so you may want to use aragonite sand in your next tank. Gravel, crushed coral substrates tend to all act as traps for debris. Also, if you ever treated the tank that gravel was in with copper meds, you may have problems with inverts.

Also do yourself a favor and take it slow. You mentioned an upgrade is right around the corner and that you will likely use uncured LR in addition to the rock you have now (which will likely be cured by then). You are going to have a cycle when you set that tank up so you will need a place to keep the life you put in the tank you have now.
 
i am going to try and 'soft cycle' the uncured liverock so everything on it and already in the tank survives... hopefully by having enought cured rock and sand, lots of water movement and even the mechanical filter media in the power filters the ammonia wont spike too high. ill attempt to keep it under control with water changes as well. the uncured rock im going to get is quite nice and i dont want to expose it to a full cycle if that makes sense?

the substrate i got from my freshwater tank is actually reef substrate... its called 'gray coast calcite' made by seachem. it has grain size from 2mm all the way down to fine dust. it looks awesoem i must say, my favourite substrate ive ever seen. good point on the copper meds and thanks for mentioning that, fortunately i have never had to use anything other than salt and melafix in this tank.

thanks for posting hopefully i will see u in here regularly as the months tick by and my tank grows :)
 
You sure did get some "lively" live rock there. Some of those corals might turn out to be some nice additions!
 
big day today. went and picked up another 8kg of cured liverock from someone who was shutting their tank down. had some baby turbo snails, a xenia and some morphs on it which made for a very nice cheap addition.

then i realised i would need a bigger tank to fit it all in!!! lol so i set up the 2x18x18 tank i had bought yesterday ;) spent all day with corals in buckets and heaters allover the place, but its finally all in the tank and fairly stable. hooray.

and then i spent a whole bunch of money and got a vortech! and some more snails :) i still cant bring myself to take out the ugly internal cannisters tho LOL i have to retrain myself i think...

Good job! I suggest adding a skimmer (you can get them cheap off ebay, and they work very well... at least mine does) and a HOB filter for a refugium... plop a little live rock rubble back there, maybe a piece of macroalgae and you're done. It gives you a place to add a little carbon or purigen when ever you want, too.
I'm so jealous as the great hitchhikers you got!! The best thing I ever got was a banded brittle star. Oh, and I got a bristle worm too. Not sure how happy I am about that yet, as I've heard bad things about them. Guess we'll wait and see as I wasn't able to catch him.
Anyway, looking forward to more posts!
 
some more pics before bed :)

snails...

the SPS seems to be surviving so far. perhaps looks a bit darker which im hoping is a good thing. cant wait to see it growing, assuming it survives...
