Good.Only snail are a bit far from us.

Bro, PM you liao

So does SPS

So far I think sulphur denitrator is the most effective to remove the high nitrate

No.I mean does the pump come with any rubber feet.Most of them have

Is there?

I don't know you (Jacky) you areso near to me. Next time go LFSing on weekend let me know What about comycus? Are you also from nearby?

Did you use the pad that come with the pump?

Did you set your white balance? Most camera on auto white balance will give you pink ring effect for blue. You have to adjust white balance up from auto till you see the pink ring go away

Nice to meet all of you. I walk through this road and meet with all sort of obstacles. Hope to share what I learn so that your path is easier than me. For the next 2 weeks I will not be available as I am off station

Our eyes cannot really tell how many watts is the LEDs by looking at the brightness. But if you say 168 leds then I think is only 1/4 watt per LED at the most. If it is 1 watt LED ,168 LEDs need a very huge piece aluminium to disspipate off the heat generated.

Blue and red is very important for photosynthsis. White has a bit of both. Depnding on what you keeping you may need to add blue or red accordingly

Why SSC LED? Seoul Semiconductor’s LED is used for lighting products of Havells Sylvania, one of Europe’s largest lighting companies 30 Sep 09 â—‹ Havells Sylvania, one of Europe’s largest lighting companies, released Concord Stadium spotlight range using Seoul Semiconductor’s Z-Power LED P4 series Seoul Semiconductor (CEO Chung Hoon Lee, www.acriche.com), a world’s leading LED manufacturer, has recently announced that Havells Sylvania, one of Europe’s largest lighting companies, released Concord Stadium spotlight range using Seoul Semiconductor’s Z-Power LED P4 series products. The products of Havells Sylvania using P4 series are characterized by their innovative design, taking the form of sports stadium light. Two kinds of products are released, including Stadium PRO and Stadium EVO, spotlights with a high color rendering index(RA=93). Stadium PRO has been specifically designed for use within museums and galleries with an onboard dimmer system, long life time(50,000hrs), and no IR or UV, while ‘Stadium EVO is ideal for retail applications. Z-Power LED P4 series delivered to Havells Sylvania are respectively W42180 (Pure White), S42180 (Natural White), N42180 (Warm White) and 16 pieces are applied to each module. Combined with Seoul Semiconductor’s own phosphor technology, Z-Power LED P4 series have a higher luminous efficacy and reliability with improved brightness, and these products boast the world’s best luminous efficiency with one chip. They can be applied not only to general lighting fixtures but also to other various areas such as architecture lighting, decoration lighting, flashlights as well as cars. In addition to this, Havells Sylvania is one of Europe’s three largest lighting companies with a sales volume of 1 billion US dollars a year, and the British corporation as a supplier of Seoul Semiconductor’s products is one of the major lighting companies specializing in LEDs and light bulbs. With regard to this delivery of Stadium spotlight products in the UK, an official of Seoul Semiconductor said, “Recently, seeing that various kinds of LED lighting products are being developed in a number of European countries including the UK, Seoul Semiconductor can deliver customized products which meet the constantly changing needs of clients. It is expected that Seoul Semiconductor’s products will be exported in large quantities not only to the UK, but also to all over Europe.â€

Is it 3 rd floor? All China LED. No publish spec to refer. No light meter to test. No side by side comparison to make You can try your luck

What type of LED you using? Look like is those 5 mm led

Owners for the Solaris will be able to answer .

Very quiet and long lasting.I have one unit running for 5 years and another running for 2 years. So far no problem

All LEDs have life for 70,000 to 100,000 hrs if connected up as manufacturer recomendation. So I personally think 5 years is nothing.Right? No manufacturer of high power LED recomend that. If fact all specify and highlight that you have to ensure good,sufficient and appropiate heat dissipation if you want your LED life to be close to the manufacturer claim. So how to run LED without fan?

Go for Eheim or Ocean Runner

Most of the LEDs users experience that. In fact this is one project the Singapore Government is funding

Have not seen any manufacturers produces LEDs to meet the difference requirements so far.(Beam angle) In fact choice of beam angle is very limited. Most major LEDs manufacturers like Cree, Luxeon, SSC ,Osram,etc produce a range of lens for different application for their own LEDs. Most of these lens is easily available on most online store. Maybe LENS for LED is like Filter for camera LENS

All necessary equipments you use must meet your tank capacity. Every piece of equiments have their own job to take care This is my opinion.

Bro, You are right in some area. But the light intensity falls greatly as the distance from the LED increase.Same for all type of lighting. Worse still your light will also be bent from its initial path due to the difference in the air and water density. So you actually need lens to bring the light spread to a narrower beam to get the require intensity and PAR as your tank go deeper. The light spread might be there but the intensity and PAR may not be there.
