Chris really can modify arh. Your tank and mine same same. Good if can, coverage at side will be better.

I do not know if this will void the warranty. As you can see, the design of the 2 fans are placed in between the 3 segment of LEDs, maybe for a reason to cool down the LEDs, or the right spot for heat dissipation of the metal frame. To me it seems like the whole metal frame is a heat sink, whereby the placement of the fan is less concerned.

That will be great, at least we seek your consensus before modifying it.

Any update, DE?

[dr evil]

factory mention not advisable to modify the light set. Was recomended to have a better coverage for 4ft by using 2 nos of 120w for 4ft

Hi Klim, from the pictures, per module is 13 number's of led? Total of 39 for your 160w model? Thanks.

Yes. if use on a 4ft both end of the tank will be quite dark

U think 2 sets of 120w is enough for 5ft? 2 sets of 160w may be too long for my tank...

yes u need 2 units of 120w for the 5ft tank.....2 units of 160w will be good for a 6ft tank

cheers!

[bubblefish000]

isit enough to cover the length if i place side by side

[khuancc]

cheers!

Can the 160w joined nicely with the 120w? I mean without any gaps in-between? Are the lens and led changeable? Thanks.

for a 4ft tank, yes.....it will fit nicely side by side

What about the LEDs? Btw, I'm the guy that bought the ati ballast and fan from you. Thinking of changing it to led. Do u have the 160w 8000k set for freshwater planted tank? Thanks.

[dr evil]

In 2 weeks time, the 8000k version will be available. Not many left as well so please book your unit now

Just tested the 160w 16k on my 4x2x2.5. The brightness is superb for Lps. However the left/right iside of tank isn't brighten up due to the 3 segment of led placing very close together. Just wondering if I can modify to spread out the LEDs to cover more area.

Initial

bar led fan led fan led bar

Modify to

Led bar fan led fan bar led

For those who has the set will understand what I mean by shifting the left led closer to the left, and right led closer to the right to spread out.

Hi Chrislwp, your tank height is 2.5'..? if yes, how is the penetration to the bottom of the tank..?

[RockyBoy]

Hi Chrislwp, your tank height is 2.5'..? if yes, how is the penetration to the bottom of the tank..?

2.5' should be no problem. Also depend how high the LEDs are from the water surface.

[alvin00us]

Bro, do you own 1..? Might be using the original stand. But prefer to hang it on the Mazarra rail frame. Not sure can support the weight for 2 120W or not.

Any Bros out there can advise on Ideal Program Timing?

I get Big Time Algae Bloom using the Preset Programs.

[tropic]

Try not to set the whites to high.50-70% white has the red spectrum

[sngolf]

Pardon my ignorance, so I should be setting the whites with no more than 70%?

and stay in the red spectrum?

[tropic]

I thnk it depends on your coral placement and height from your water level. Can slowly acclimatize them rather than setting all 100%... Some other forums also has reefers recommending not to set till 100%

[tropic]

Anyway are the algae bloom cause of light or something else? Any bleaching?

[sngolf]

R420 16K has been on my first mixed Tank(3 X 1.5 X 2), got some fishes, LPS with SPS Frags,

Algae and cyno bloomed when I used the presets.

Been setting it down to no more than 80% for a week now.

Algae and cyno clearing up, did a big time clean up.

Some of the SPS Frag bleached out, while a few SPS with brown algae on tips.

Also clearing up, been cleaning it with a soft tooth brush.

I just got another Razor 420 10k for my 4 ft X 1.5 X 2.

This is more of a FOWLER Tank with soft corals, trying to be careful not to have another Algae Bloom.

Appreciate your advise on ideal settings for both Tanks.
