Thx.. Not all rocks are natural live rocks, some are made using white cement and coral chips. Thats how I get the shape I want.

Update:-

Red... My nutrients are on the high side so no additional feeding done... Tigger... I'm using H&S skimmer as well as a CR..

Rescaping the entire tank.. will post pics when completed.

Coralline...

This is a little hard to say.. Every1 has their own pref.. Manufacturer says 8mths, but they can sure last longer depending on the K. 6.5k can last for years according to many in US. While > 10k said to last abt 1.5-2yr on 2ft depth.. then again.. intensity gone by then.

Not lose spectrum, just lose intensity. 6.5k bulbs have the best growth rates as they have all the spectrums covered nicely, but the colours are not that great. Growth and colour are two different things so don't mix them up. What BH has said is true and must be considered at all times else your SPS will turn white and say bye bye. Why SPS turn white? Simple.. white consists of what colour spectrums? So too much of all spectrum forces the SPS to try to reflect all the spectrum. Thk I'll confuse more ppl here

Anything that shows red needs iwasaki type of light. Anything that shows blue needs 20k type of light. This is only for colour, no consideration of intensity.

wah i confused so many.. Intensity and Spectrum are 2 different things. Blue spectrum (blue light) penetrates the water deep but the intensity is not great as such with a tank that is >2 ft deep is best to use 400w 20k MH or more T5s Actinic. The yellow spectrum (Iwasaki - 6.5k) has very high intensity but the spectrum does not reach deep. To reach deep, we need higher wattage (high risk as the surface water will be very hot).

ham..That topic think was covered somewhere liow.. I not guru abt this so I too experimenting, so far got some results showing.

This is from XM 10k SE bulb.

hehe when i first read also blurr... ok simple explaination. > SPS that shows orange/red colour, needs 550-600 nm spectrum of the light. > SPS that shows purple/blue colour, needs 310-380 nm spectrum of the light. > SPS that shows blue/green colour, needs 380-470 nm spectrum of the light. >SPS that shows green/yellow colour, needs 430-490 nm spectrum of the light. > SPS that shows yellow colour, needs 440-500 nm spectrum of the light. >SPS that shows Red/Orange colour, needs 500-540 nm spectrum of the light. I see if can find the light spectrum chart, then will make it easier to understand.

Its a long thread so hope this helps. Summerise: Pocilloporin is the fluorescent cells on the SPS. SPS absorbs one light spectrum and displays out another. >Pocilloporin primarily absorbs green/yellow (550-600 nm) light along with some upper UV-A . it emmits a orange/red >highly fluorescent pocilloporins primarily absorbs light from 310 to 380 nm (UV-B and UV-A) and then fluoresces this as light from 400 to 470 nm (violet/blue). >highly fluorescent pocilloporin primarily absorbs light from 380 to 470 nm (UV-A, violet and blue) and fluoresces light from 475 to 520 nm (blue and green). >third type of highly fluorescent pocilloporin primarily absorbs light from 430 to 490 nm (violet and blue) and fluoresces light from 490 to 540 nm (green/yellow). >Yellow fluorescing pocilloporin primarily absorbs light from 440 to 500 nm (blue) and fluoresces light from 520 to 620 nm (green, yellow and orange). >Red/Orange Fluorescing pocilloporin that primarily absorbs light from 500 to 540 nm (green) and fluoresces light with wavelengths that are primarily orange to red.

I found this forum site that would really help those into SPS. http://www.reeffrontiers.com/forums/showth...15&pagenumber=1

alot of skeletons showing.. still can recover, best don't move it else will stress it further.. T5 are ok..

Testing my shots..

Thx.. Would they sell the ballast as well?
