ATI power module 10×54w

[Yanir38]

Hello reefers !
my tank is 1 year old , and right now I'm using ATI power module 10×54w . my tank dimensions are :
140 cm long
70 cm wide
55 cm high

i have used the ATI power module hybrid 8×54w and 3×75w of leds.
it was nice , but it seems that the LED's was with horrible narrow beam that fries some of my sps.
Because of that I made the switch to 10×54w.
I can see that most of the SPS showing good health and good grow

But , I'm still debating what is the optimal mount for this fixture.
I mean how high should I hang above the tank ?

Also what is the recommended bulbs combination?

right now it's hait's0 cm above the tank (its pretty high) , because I don't want to burn my SPS.

I had running my T5 fixtures about 15 cm above the water surface. If you like to you can lower it in two steps to prevent issues.

Not sure which bulbs form which manufacturer you plan to use but basically this would be a good combination for a 8 bulb fixture:

5 x white (14k)
2 x blue
1 x purple

Should give you a white, clean natural look.

Good morning.

6 months ago I used a Apolgee Mq-510 from a importer.

excited and disappointed at the same time.

tank 1500x65x65

I run 8 T5 fixture 54w (1200 long)

9inch above the water.

Bulbs - b+ p+ b+ ab b+ p+ b+b+

this combo many years ago was what the grimreaper off reef central use to recommend but with 6500k bulb instead of the ab+. (6500k been to yellow that why ab+ is there now )

coral siting 12 inched below the water
120-180-220-180-120

on the sand bed
160-180-200-180-120
found the ligh to be biases to the front of the tank even tho it’s centered

Just out of interest I change the bulb combination

removed the p+ (x2) and replaced them with C+
Coral sitting 12 below water line
150-280-330-260-150

sand bed was 150-200-220-200-150

next change was replacing the c+ (x2) with KZ coral light new gen

12 below water
360-400-400-400-360.

Sand bed peek centered 260

I was excited to find out what was what, as I had never known or measured the light.
Just changing 2 bulbs and what what changes in par

The disappointment was par falling off on the ends of the fixture.
All the test brs and other place post on T5 seem to be very even. But looking back they use a smaller fixture 600( 24w) and they assume the longer fixtures are going to be the same ??
Maybe it could just be my fixture ??

It’s all interesting 🤔

Hello, I did PAR test with my 10×54w , sand is at 250 , top of the rocks is at 550 .
im also using Apogee MQ-501 , in the software there is option that called "immerg settings" .
you have to activate this option , because that is the only way that it will read the correct PAR levels.
By activating this option, PAR readings will be 15% to 20% more.

What height is the fixture above the water and the rock below the water for u you out readings.

Did you park fall alway half off centre - or was it even all the way along ??

Thanks, I was given the meter to use, no instructions- turn on and GO. (Read screen) no downloading.
I’ll remember this next time.

The fixture right now is 29 cm above water.
the rock are 20 cm from the water surface.
I remind you that it is 10 bulbs fixture , not 8 bulbs.
if you PAR meter is not connected to computer and have its own controller , the yous should multiply the PAR results with 1.25
for example, if you get PAR reading of 300 ,then the real number is 300×1.25 = 375 .
That is officiall answer that I got from Apogee.
