Ong Dai Lin, Today Online - They have been hauled to court many times for staging protests and other activities in public, with a guilty verdict the regular outcome. Yesterday, however, a group of Singapore Democratic Party (SDP) leaders and activists were acquitted of holding a procession without a permit. On Sept 16, 2007, five of them had marched from Speakers' Corner to Queenstown Remand Prison to mark the first anniversary of a protest led by SDP secretary-general Chee Soon Juan at the World Bank-International Monetary Fund meetings in 2006. The group, comprising SDP chairman Gandhi Ambalam, assistant secretary-general John Tan, central executive committee member Chee Siok Chin, SDP supporter Yap Keng Ho and human rights activist Chong Kai Xiong, also wore white T-shirts with the words "Democracy Now" and "Freedom Now". In his written judgment, District Judge John Ng noted that the group had walked mainly on pedestrian pathways and did not attract "any significant" attention of the public. They also did not carry any of the usual equipment associated with a protest, such as placards or banners, and the walk did not disrupt pedestrian flow. The judge said: "It was a group of people walking purposefully in a public place from one point to another, but on this occasion, it never amounted to a procession." He added that there has to be a distinction drawn between "walking in a group from one point to another, even if it was to commemorate an event, and being part of a procession". When contacted, Institute of Policy Studies senior research fellow Gillian Koh told MediaCorp: "The judgment suggests at face value that there are political activities that seem to be acceptable which we never thought would be allowed." She said that political activists should look at the previous cases and the specifics of the judgment, and "they would want to be cautious in staging political activities in order to avoid running afoul of various laws". The five SDP leaders and activists had been charged for participating in a procession without a valid permit. Each of them could have been fined up to $1,000 if convicted.

hehe reporting! comycus from upper bukit timah!

Bro live rocks that have been established in another reefer's tank is actually good for you. Some might have coralline algae to help you seed the rest of your rocks, and they are relatively stable, and you get at a fraction of the price compared to buying elsewhere. Do check with the seller though if he's selling live or dead rocks. No indication if they are live.

lol so bad... yeah the rule is arbitrary, especially when technology nowadays has all these IR, VR, stabilisation stuff. Guys, u take really beautiful shots of your tank, maybe wanna share your camera settings, thought process, preparation work, post processing? bro you are damn pro!
-
BEAUTIFUL! heh wish i could take those shots...

Shutter Speed Shutter speed is the amount of time that the shutter remains open. Faster shutter speed = less light enter camera = darker photos = motion freeze Example: When taking photos of corals, we can afford to have a tad longer shutter speeds while maintaining photo sharpness, provided the coral doesn't move, with the use of a tripod. This will allow us to shoot at lower ISO setting, thus having better photo quality. However, we do not have the luxury of shooting at lower shutter speeds when taking photos of fishes. This is because we need to freeze the motion of fishes, and thus will need to employ higher shutter speeds, thus resulting in the need to either take at a higher ISO setting, or with a bigger aperture. I find the norm for capturing swimming fishes is to shoot at least at 1/100 (.0001 second) or higher. Some examples to illustrate this. ISO200, 1/20 F5.6 (my royal gamma swim too fast, unable to capture anything) ISO800, 1/100 F5.6 (Managed to capture my leopard wrasse w/o much loss in exposure) Some techniques we can learn to master to help us. As you can see, I'm limited by aperture size because of my kit lens, and ISO settings due to my old d60. Does tt mean we need to succumb to the BBB Syndrome? Not true... Panning technique in 3 simple steps 1. Select a slightly lower shutter speed (<1/60) 2. Track your subject (fish) with your camera 3. As you release your shutter, continue to move the camera with the fish. ISO 200, 1/20 F5.6 If that's not enough, change your release mode from single shot to continuous and pan at the same time. This gives you more margin of error as you take multiple shots, and hopefully 1 comes out right. ISO 400, 1/20 F5.6

lol dude, i'm sure he wanted to focus on the dog's eyes, but because the dog moves too much too fast, it's almost impossible to hit it spot on all the time. Tt's why big apertures may be good in allowing faster shutter speeds, but results in v. shallow depth of field, therefore the margin of error is alot higher, miss the spot, and you are out of focus straightaway. Besides at such shallow dof, if I get the eyes in focus, the nose and ears might be oof. That's why I'm starting off with the so called exposure triangle. Because there are always pros and cons for adjusting each of them, if one has the knowledge, hopefully it will improve your thought process before planning a shot, and hopefully result in better photos. Theory la... as usual theory is easy, practice makes perfect I will move on to shutter speed next.

To all wrasse lovers... Taken from Wikipedia: The word "wrasse" comes via Cornish from the Welsh word gwrach meaning an old woman or hag. Just some food for thought... I'm trying to kill time before my meeting.

bro paiseh, I take back what I said this morning about algae scrubber and carbon. An ATS will remove large amounts of organic compounds, with large amounts of nutrient uptake. The drawback is the algae can yellow the water. Systems that run ATS will need activated carbon to keep the water crystal clear. One of the major benefits of an ATS is the amount of zooplankton that will proliferate in the turf algae, whose larvae make great zooplankton for coral food. http://www.advancedaquarist.com/2007/9/diy

I want myself a pirate ship tank too!

lol i had to dig up old threads to find ures! Think must make a list on sharing the blue tub le... anyone wants to do tank migration can 'borrow' from src. idea?
-
bro u will need more rock if not for filtration purposes, but for future coral purchases. 3ft tank will look v. bare with so few rocks. But it's not compulsory, if you like less rock, then go for the open, zenlike look. Bio filtration can always be handled in the sump using bio home or more live rocks in future as your bioload increases. There was a thread previously on how to do tank transfer, you can read more about it here: http://www.sgreefclub.com/forum/index.php?...p;hl=3ft+to+4ft

wow if I cycle a new tank and hypo the LR, would tt mean tt I get an ammonia spike + kill off hitchhikers kill 2 birds with 1 stone?
-
heh no la, must be win big prize but then i dun buy lottery... how ah?
-
The other concern, of course is the focusing distance. Won't be able to work if we can only focus 3" away from subject. I will dig out my old cd rom and try it out this weekend! Once again, cool stuff!
-
haa me not santa claus, but if strike lottery wun forget u guys one la! 1 pair each!

Just to add, after seeing the photos taken, light will be a concern when using this 'hack'. Because the phone will be v. close to subject and might have shadow cast on it. Actually this is true of macro photography in general, so need to find a way to ensure enough light Binosage can provide a rough indication of how close you had to take to get those 2 photos?
-
Awesome! I never thought our camera phone could be so useful! thx binosage! Let's share more stuff here guys!
-
thx, I find v. long for it le... Tell you what, next time u go choose and reserve for us coz you pro, I will collect another day for both of us. Whether I pay for both of us depends on your luck le
-
Just my observations. Saw duncanl36 01:45PM post with "Okay , so heres a photo". Then, checked back later and it was changed to "Just relax". 01:49PM GheyLord posted "Okay , so heres a photo" I rest my case. No I have no proof on this, just my eyes.

Is your tank water yellowish in the first place? If running RO water, there shouldn't be impurities in the water in the first place right? There are advocates of running carbon 24/7, others who only run carbon when needed. If your tank is doing fine, then I would suggest not changing anything unless you have strong reason to believe adding something will only result in a change for the better. You would also want to monitor your tank for any changes, good or bad. What's working for others might not work for you, best is to monitor and gauge for yourself.

I say your lineopunctatus colours are really amazing! Time to scout for the holy grail bro
-
omg! yeah with parents like ours, I think tank's much safer not doing anything. Just get an auto feeder and put in just enough food for 1 feeding a day. Fish are made of better stuff and will still survive if you put them on a diet regime for 10 days. Just clean/maintain everything before you leave and make sure everything is in working order. If you really prefer to have someone on hand, I would suggest having a reefer you trust drop by from time to time to check on the tank. I mean if chiller pump spoil or some other more technical stuff, I don't think my parents or neighbours will be able to do anything about it, in the end will call me to check, and spoil my holiday.

Re: Reduce Nitrate Level in Fish-only Tank
comycus replied to tench1's topic in General Reefkeeping_
Bro, I don't think dosing bacteria will instantly bring down such a high amount of nitrates. My own experience after dosing bacteria and az-no3, took about 2-3 weeks to bring down nitrates from 50ppm to <5ppm. Anyway dosing vodka needs to be done on a daily basis, so I also assume it would take some time to see the results. Prodibio products are dosed every 2 weeks, I believe the results will also take time.
