  1. ATI Sunpower dimmable also offers timers and dimmable controls, so that actually sounds very adequate.

    But I must say that thunder and cloud modes are very tempting cool feature. I thought day/night cycle already very good feature, until I realize LEDs can offer this kind of "weather mode". And must say the interface offered by Radion is very solid marketing, imagine playing god and changing the "weather" from my ipad.

    But are LED bulb replacement must more costly than to replace T5 bulbs? any figure to advise?

    Yo bro. Led also have timer and dimmable controls plus all those fanciful mode like thunder, cloud, etc.

    Lifespan wise, led is 50000 hours or something like that. But led can lost up to 30% of their intensity in a year.

    Bro. Not all led offers replacement light pad de. So easier to buy more wattage than u need and buy new light set after two years.

    Yup, it is a very nice and relaxing sat afternoon to watch slow cloud moving over ur tank and watch the fish and coral react to the passing cloud

  2. Came across ATI, and there is a LED/T5 Hybrid, so best of both worlds. Not sure about the cost. but its really like in-between and not taking sides.

    What I gather so far, T5 is well-known and proven for its strong lighting, but it seems like LED can do alot more fancy configuration/setting.

    It is quite tempting to go along with LED, but at the same time, T5 still seems like the best-value for money. T5 also has dimmable fixtures, so what gives from the LED camp? Hmm..

    I read about people changing T5 bulbs due to their limited lifespan, but what about LED bulbs?

  3. 28/04/15 - SPS and Zoas

    As usual, FTS for this update

    Somehow, my updates have changed from a weekly update to a monthly update liao. Partly because I have been traveling quite a fair bit for the last months but also because I have already gotten most of my coral in place so there is not much I can buy or play around with.

    Two particularly painful incidents happened in the last month,

    1) My chiller was down for half a day (luckily I am in SG for that day). Temperature shot up to 32.X degree and by the time I got home, several LPS has melted compare to only one SPS (BN) has peeled. Funny tho, I always thought SPS are the more vulnerable one.

    2) During one of the weeks when I was away, the HOB canister that I linked that output to two FR (housing bio-sphere and NP bio-pellets) died. I did not think much and just restart the canister after I get home. Big big mistake. Tonnes of hydrogen sulfide was released into my tank. The whole tank smells like century eggs. Three fishes die almost immediately.

    On top of these two stupid incidents, by and large I have a happy month reefing. GHA is almost down to 5%, SPS is growing, zoas are growing more so. Fishes are eating well.

    I guess I will spend the next few weeks buying zoas to fill in the gap between SPS and watch both them grow.

    Random photos and a feeding video as of 28 Apr 2015 (Before I am away again)

  4. what UV kills depend on the contact time and spectrum, but by and large it will kill any floating virus and bacteria in the water, and yes, it includes good bacteria too.

    how you put your UV in sump? is your UV is those exposed UV i.e. can see visible light de?
