LiveRock

Sorry, too overwhelming responses that I can't reply or SMS individually. My tank was more than 2 years and these rocks should be cured. I will be selling other stuffs like UV, Ehiem filter, skimmer later too after I cleaned up everything. UPS will not help in my situation as it won't last whole days. I have APC UPS, by the way.

Came back heart-broken last night to realise that power has tripped and all my fishes and corals are dead or half-dead. Decided to give up hobby once and for all since this is not the first time the ELCB tripped. I have rescued the situation many times but last night's one is the ultimate tragedy. My area Woodlands is so prone to lightning that when there is a thunder storm, the lightning and thunder are terrifying; and power is most certainly to spike. Well.... I am clearing first my Live Rocks, now in a pail of circulating new salt water. They won't last so I must let go all by today. Just S$2 per rock. Interested, please call 90909214. Please bring own container and call me first. I am in Woodlands.

Interested in zoo. Got picture?

I am interested. How much, how big?

Interested in 2 cleaners and starfish. Please PM me. thanks!

interested!

Version 3: Moonbar for the wider tanks

Version 2: Slimmoon (made with Swatch Watch casings) Day View Evening View

Day View Night View

HI I have been DIYing moonlight previously. In fact, the moonlight has gone thru 3 versions Version 1: Compact but Powerful

Sold! Thanks for all the inquries.

Ya, made it and somehow, the person who ordered it is now missing. So, here is it, at $45 instead of S$50. New and unused. Basic Specs: 10 x Blue LED Over-Current Protected Comes with AC Adaptor, ready to run. Interested, please PM me. Thanks!

I got a rock with purple/blue mushrooms from ML, within a month, they fade to brown!!!! Placement is middle, with MH. Sigh....

Hi guys I'm interested in the game industry. Is there one in Singapore? Woonming, u got lobang? Thanks!

Hi onghm nice abstract... here it is: Abstract: In many species of symbiotic corals, spawning occurs synchronously several nights after the full moon. This process is correlated with the level of lunar irradiance, but the mechanism by which these cnidarian/zooxanthellate symbioses can detect such low levels of light remains unknown. Here we report the first biophysical evidence that the host animal exhibits extraordinarily sensitive photoreception in the blue region of the spectrum. Using a high-resolution laser-induced signal to detect tentacle scattering, we measured the effect of low irradiance on the contraction of polyps in the corals that normally have their tentacles extended in darkness. Similar to most deep-sea invertebrates, the action spectra of coral photoreception reveal a maximum sensitivity in the blue, at 480 nm, with a spectral band width (at full-width half-maximum) of ca. 110 nm. The spectra closely overlap the maximal transparency of oligotrophic tropical waters, thus optimizing the perception of low light at depth. The detected threshold of photoreception sensitivity is ~1.2 X l015 quanta m-2 s-1 in the blue region. This makes corals capable of sensing the blue portion of lunar irradiance, as evidenced from the recorded slight contractions of polyp tentacles under variations in moonlight intensity

wow! The discussion is really interesting! Talking about SimCity, we should also have SimAquarium with all the moonphases, tides, mists, meteor showers, rain, fresh air, etc. ha haha ha.... Anyway, I always try to approach a problem using the most simple solution I can find. First we define what we want, the main objective. In this case, the first objective, like AT mentioned, is to have a suitable nightlight to observe the activities at night, so you leverage on your investment, which is your tank. Now you can actually enjoy your tank 24 hours a day, even in the middle of the night when you wake up to do your business Other 'benefits' like spawning, killing parasites, etc. are not guranteed However, I do think that varying the LED intensity whether automatically or manually, is a valid and important user requirement. The wavelength of the light is also important because the light reaching the corals in nature is invariably blue, after the absorption in the water. Yes, lets work together for a moonlight that is affordable and meets the primary needs. Cheers!

Hi Ian Me too late? For small one, use in 1 feet tank?

cheapest in the market? What is the price?

S$200+ with a yellowish bulb. Paid another S$100 for the 20,000K Saki.

An old picture of my tank (front view) is in the DIY section under Moonlight : Reloaded

Technially, to simulate the the moon light intensity cycle by switching the number of LEDs to be switched on is no problem. The challenge is to design the circuit for optimum space, lowest costs and ease of use. Hmm... maybe I should do a bit of R&D on this area... BUT.... if nobody wants it after my research, then how? Anyway.... I may look into other possible solutions... like varying the intensity of all the LEDs together instead of switching on/off of individual LED?

Price is S$50 including the power adaptor ready to run.

Hello there This is the new moonlight, called moonbar, for the bigger tank. It is slightly less than 2 feet long, has 10 LEDs, and comes with its own power adaptor.
