    Good Tank Maker

    in Sell off/Pasar Malam Shop

    Posted · Edited by DeepBlue

    tks for all e suggestion.

    Actually im looking for a 3ft by 2ft by 2ft with 10mm thickness plus cabinet.Oso w e sump tank n pipling all done.

    Got a shop offering me $1500 for all e above + lgt n pump in it.

    Another deal is $2500 with all e above plus 40kg of live rocks,12 coral n 12 fishes of any value..N of course plus setup oso...Is 12 coral too much w/o a chiller???huh???

    Do u guys think its a gd deal??

    huh..... <_<

    Actually im new to all tis lor..So wan to lok for a package things to prevent later go buy other parts myself then cannot fit... :D

    Any advise for a newbies lik me???

    tks... :peace:

    PLEASE tell me you are not getting these quotes from ATLA*** at IMM. :unsure:

    How do you import corals?

    Unfortunately, I am a civil servant myself.

    Fortunately, it means I get to see first hand how taxpayer money is wasted. And I mean wasted.

    Just because a school approves a project does not mean the school gave proper consideration to the likelihood of any real results emerging from the project. Sure, it looks good to MOE that you have "cheem" sounding projects handled by your students, but that doesn't mean you know what you're doing when you allow money to be spent on buying exotic corals. No doubt the principal and whoever else approved the project doesn't fully understand the implications of what they supposedly agreed to. Even the teacher with the "Masters in Aquaculture"... no offence but if that piece of education were so useful it would be better applied to a marine research institute or lecturing in some university course rather than to waste it as a teacher in a secondary school no doubt conducting O level biology at most.

    BH, do recognise that asking people to donate expensive exotic frags for your brood stock so that you can sell it is like asking people to give you their rare breeds of kittens and puppies so that you can breed them yourself and sell. And all in the name of conservation too. There is a reason why there is a market out there to buy and sell frags.

    Don't get me wrong. I'm not knocking what a secondary school life sciences facility can do. My good friend won an international young nobel prize award for his thesis on chaos theory when we were in JC1. All I'm saying is that you need to be realistic about what you will probably be able to do. Limited funds (compared to huge marine facilities with wall-to-wall tanks), limited expertise (full-time PhD trained researchers) and limited size (not many students your age will be as well read and committed to the marine hobby as you) will mean your school cannot hope to reproduce the level of work being churned out at big institutes around the world. And there is no running away from the basic courses in related sciences that you must take as a foundation to study the more complex aspects of marine biology.

    At the end of the day, I repeat my stand on this. If you say the school is doing it for educational purposes, to get students interested and aware of the basics of coral culturing etc, fine. To say it is about conservation and genetic manipulation of corals I think you ought to re-examine your goals a little more carefully.

    Anyway hope your project is a success, it will definitely be an interesting thing for students. Wish I'd had that when I was in school. Don't be surprised, though, if you find nobody rushing over to donate their coral frags to your brood stock. Just isn't realistic.

    How do you import corals?

    in General Reefkeeping_

    No offence BH, but I think you gotta be clear what your objectives are. There's no way the budget of a secondary school in Singapore can contribute meaningfully to conservation efforts of corals, considering the scale at which destruction is taking place. If it is for learning and basic research, that's one thing. You can't repopulate a reef with brood stocks. I agree with AT, studying how to increase the survivability of corals in harsh water conditions or improving viral resistance are far more useful than colour tinkering with halogens.

    In addition, looking for "fine specimens" that LFS keep for themselves sounds commercial and not scientific in the least. People consider specimens "fine" because of shape and colouration. This has no relation at all to importance of the specimen to the ecosystem and what part it plays in the bigger picture. If you go down that route, you will have a nice collection of "fine specimens" which will be ultimately useless for conservation or even mere research since the "not-so-fine" specimens (optically) are equally, if not more, important to the ecosystem. If you intend to conduct a serious study on this subject and to educate other students on it, you will do well to have a broad mix of corals rather than just zoom in on the "nice specimens". :erm:

    Recommendations For Chillers?

    in Product Reviews

    Posted

    actually you are right, and i think there are many reefers doing that method, and i am switching to it too. The idea is that if your return from the chiller goes direct to the tank, it has 3 benefits:

    1) chilled water goes directly to main tank, making cooling more efficient

    2) acts as extra pump to increase the rate which water is cycled through the entire tank and sump setup

    3) in case of main return pump failure, acts as a backup to keep some kind of flow going, though much weaker. still better than nothing.

    as to earlier comments by clowntrigger about how increasing flowrate makes it slower to cool down his tank, it is not strange at all. it makes perfect sense that this should happen. for heat exchange, the rate at which heat is transferred from a warm object to a cooler object is related to the difference in temperature between the two. i.e. if you put a warm cup into cool water, the water will slowly rise in temperature and the cup will slowly cool down. But if you put a boiling hot cup into freezing cold water, the temperature of the water will rise much faster and the temperature of the cup will drop much faster.

    because of this, if you have a slower rate of flow, your chiller return water is coming out much colder into your tank and the heat from the warmer water is being absorbed into this chilled water at a much higher rate than if your chiller return water is not so cold.

    similarly, the warmer the water going into the chiller, the faster the rate at which the heat from the water is removed by the chiller. thus, if fairly warm water is constantly going into the chiller, the cooling effect is more efficient than if colder water is going in. if your flow rate is higher, it increases the chance that already-cooled water in your main tank finds its way back out of your tank into your chiller, and then you get inefficient chilling.

    hope you guys arent too confused... cos i am almost confused myself!! :blink:

    Atl*ntis is well known for their crap services... they only know how to blow smoke in ur face and charge exorbitant prices.

    I know of some frens who got a system by them too and seriously the system they help you set up is all rubbish. My fren's fishes dropped like flies over a few months... they cover up for everything by giving aesthetic value but everything else is a death trap... you pay so much but get next to nothing :angry:

    sad to say i also kena suckered by that idiot from Atl****s. complete waste of money. now i am scrapping the useless tank he provided and making a brand new one with sump and everything. many thanks to the numerous bros in SRC who helped otherwise i will have a fish-graveyard in my house. For example, he gave me a bunch of "starter fish" to put inside as soon as tank set up. At that time I knew nothing about cycling the tank. He said "fish sure die at the start, must put more see which survive". Guess what, out of 18 fish, 4 survived. FOUR!!! for the first week i was scooping out dead fish EVERYDAY. Made me darn angry :angry:

    After several months of biding my time and talking to a lot of people and reading reading reading about marine fish, I now know I have a piece of crap in my house and have to re-do the system basically from ground-up. Don't go by IMM much nowadays but if I see him again I will give him a piece of my mind :angry:

    biscan? he is croatian. and he is not as bad as we used to think, just that houllier tried to make him a centre half when he is a midfielder.

    yes, the senegal players were flops.

    in fact, i hope benitez clears out the "houllier-rot" that still exists in the team...

    get rid of traore, hyypia, hamann, henchoz, diao, biscan....

    get more players like alonso, garcia... :eyebrow:

    not all la. but is those that have it usually due to lack of anemone problem la. ;)

    don't think anemone has anything to do with this. the closest connection could be that the clown *might* be less stressed if it has an anemone to hide in, which helps it to fight infection better. other than that, no basis for saying that a clown without anemone will be prone to disease.
