  1. Funny... but your 'refugium' isn't a refugium by real definition!

    It's a coral tank!

    A refugium would be macroalgae dominated, allowing pods and worms to grow without fear of predation by any livestock in the tank.

    It's a place of 'refuge' for them so to speak! And a refugium is commonly used for natural filtration by all the algae....

    I see no such function in your 'refugium', Phang... heh!

    Hey Phang... if you are really lost about your main tank maker... why not use mine? He did a good job on mine!

    :lol:

    funny i was thinking of the same thing too.... but never dawn to me to ask.. :huh:

  2. I'm not saying you can't. They will survive, but won't thrive and don't expect them to be anything but brown in colour. LPS and softies will look so much better.

    Also, I'm quite sure you know, but just to remind you, SPS is not just about light, temperature and water quality is crucial.

    I know...i am only trying to venture to hard corals after playing around with my tank and i am quite satisfied with my water quality...

    But i think i rather not go with SPS.... Wouldn't want them looking dull when they can look so much better in some other tank...

    I think i will just go with Softies and LPS...

    Any beautiful softies or LPS to recomemnd???

  3. Just wanna find out, would it be better if i use a 1700k Pl or a actnic Pl for the corals to glow... which is better actnic PL or actnic FL???

    I was at downtown east LFS, saw a nano tank they setup...very nice looking ... noticed the pl light they use has one white strip and one blue strip. what Pl is that???

    another thing, wads the diff between a normal ballast and an electronic one. which is better and why???

  4. i once had a brown knobbed starfish. A real beauty... It was given to me by my fathers fren. I used to put my fish meat or shrimp meat directly under the starfish or sometimes just leave it nearby... i was astonished to see how the starfish raced to the point... dun noe how it smelled the food.

    There was once i forgot to feed it and it went around and digested two goni (given by the same person)... what an expensive meal.

    Unfortunatly, my pistol shrimp who was doing some underground excuvation caused one the rocks to fall on my starfish... and i didn't noe it.

    My starfish wasn't moving for a week and when i found out , it was with a deep cut and the a rock on top of it. ( funny i didn't see the rock on top of it for a week) and the starfish started smelling so i had to remove it.

  5. pH tests are one of the most useless kits because your tank 's pH will stay naturally constant if the alk and buffers are maintained. Anyway, I think that the Ocean Free bacteria doesn't work well but I like Cycle. Don't bother to continually add bacteria every few weeks though because it will not be needed .

    Seriously, i have not used any PH test kit for my tank up till now....

    Is 'cycle' a brand of bottled bacteria????

  6. Rocky...

    a skimmer is highly recommended for marine tanks. It helps by removing certain organics before it reaches the bio filterations... Should definitely be included in your list. Dun skimp on this one and dun buy a cheap one.... get a good one so u wun regret later.... not all skimmer works as they claim... some are even hard to tune.... why Dun u look at some previous treads abt skimmers... might help u alot or just ask some experienced buddys over here...

  7. I wasn't considering glass beads but was once thinking of plastic beads....

    But i too had the same idealogy as u AT... i was afraid that the bacteria might be able to colonize the surface....

    Tanzy can the glass beads support bacteria growth...

    Pls enlighten me more on this glass beads...OM :ph34r:

  8. Mr annoyomous,

    If you do not like the price you dun have to buy it... Tanzy is just selling off what he doesn't need. He is giving out alot for that sum of money... its abit n the high side because of its quality and the quantity... Its not really nice and fair to attack tanzy like that...

    Uncomfortabe with price is ok...tanzy is not forcing u to buy...

  9. sorry for posting too much... heres what i found..

    A denitrator is a very simple device, and sometimes bio-media is added to the first four or five columns of the flat-denitrator types, to produce a larger bacteria colony for the nitrosominos and nitrobacter to do their thing.

    Basically, as the water follows its journey through the system, the beneficial bacteria colonizes and begins to work. I don't need to get into how a wet/dry works, but the principle is the same for the first part of your denitrator. As the flow continues and oxygen is depleted, other beneficial bacteria take over, they are neither aerobic nor anaerobic, they are facultatively aerobic/anaerobic, commonly called nitrate respirators, sort of in limbo, not very technical but who cares. Once the oxygen is exhausted, this section of the denitrator becomes anaerobic and then these little bacteria guys take over and eat the nitrates produced by the aerobic bacteria in the preceeding stages. It is beneficial to have as much facultatively aerobic/anaerobic bacteria as possible. That is why you adjust your denitrator so that these little guys populate almost to the end of the line.

    Its not the aerobic or anaerobic bacteria which breaks down the nitrate but another group of bacteria which only survives in oxygen free water....

    Maybe thats why no feeding????

    comments???

  10. Phang,

    the 50ft of tubing ensures u that the water is completely free from oxygen(no oxygen)... normal denitrators need feeding becos there is presence of little oxygen(low oxygen) even with low flow rate. If what u say is true, that bacteria needs somt to sustain them in oxygen free environment then a DSB would definitly need feeding... A DSB doesn't need feeding becos its almost zero oxygen.... No oxygen and low Oxygen makes alot of diff...

    Barra got ur point.. besides did u buy the tube from pet provision which sells the 50m coil tube for 7.50
