Mars Aqua Chinese LED review (Ebay)

How is the spread on the photon 24 over your 40B? I am torn between getting 2 ocean revives, the marsaqua 300w or upping my budget (quite a bit) for a reefbreeders 24.

is the RB juice worth the extra squeeze over the marsaqua??

I'm getting great coverage over my 40b with just a Reef breeders 24. I have it about 8 inches over the water. Max 50 blue 45 white and there is plenty to grow easy sps. Not sure how much better it would be turned up.

Does anyone have any pictures of corals poping with the actinic turned up? I saw one of these Mars Aqua lights at a LFS I believe. Any pictures of Acans?
 
Does anyone make one of the 300w longer versions with the timer built in and single plugs like some of the smaller units have? I have a 180 gal. 6' tank, was going to use 3 of the 165 watt versions but I would get more coverage out of 2 of the 300 watt versions.

The blue makes fluorescent corals pop really nicely. Good to hear about the par readings. Mine are still 6 inches off the surface and 24" deep tank. And I run 75 blue and 50 white. I didn't bleach any corals and my sps coral is 5 inches under the surface and loves it. My maxima is in the substrate and is fine.

I am thinking of getting 2 of the 165watts for my 36Lx18Wx24H. I can only mount these about 6 inches above my tank (Sitting on the canopy). Are you getting any shadowing in the corners of your tank?
 
Whats your guys cost per month for these lights? I assume most people run the blues around 75% and White a lot less.
 
Hi

I currently have a model very similar to mars LED lights mine are 165w Chinese led light over a LED frag tank but not sure what intensity to run these at. My tank is 36 x 12x 15. The tank is 15" high and the light sits about 20" high from bottom of the tank. So about 5" from the top of the tank. I only about 10" worth of water in the tank so from the waterline to the LED its about 10" distance. Volume of water is about 70L, Sorry i know its confusing.

I have had some hammer corals in there and some zoas and Duncan coral with some Favia, everything is doing well except the hammer coral. It has gone from a fairly strong green colour to a pale transparent colour in 2 months I have had them in there. I suspect it might be the light as the nitrates in there is about 2ppm -5ppm and phosphates sit about 0.024-0.03-0.04. I am getting some considerable algae growth in there which I assume is keeping nutrients in check because i was feeding the corals once a week. I clean the algae and do water changes every week.

I run these LED at about 35% white Channel and also 35% the blue channel. Is my intensity too low or too high, since the light is not situated very high off the tank is the reason why i have not ventured up much higher than these levels.

any advice would be appreciated.

Dimmer One(28 LEDs): Cool White 14,000k, Warm White 2700k, Red 660nm, Green 520nm


Dimmer Two(27 LEDs): Royal Blue, Purple ,Blue
 
@Lpspsclown
Borrow a PAR meter. You be trying for 200 PAR or below, especially with LPS.
Please take a look at Dana Riddle's video from MACNA 2016 I referenced up thread. It explains it very well.

It's killing me that the Chinese factory for popular grow is delaying my led. And that I have to pay the duty fee when it arrives. I have no clue how to calculate that.

Wish I had a friend with a par meter for this. I'll check my local club.

Killing me!
 
Anyone know the thread size/pitch of the hangers? I am working on an alternative mounting setup and want to replace the hangers with bolts..

TIA.
 
Most of these are made by the same manufacturer with some branding slap on to them.

Here's the video of me actually replacing the diodes by desoldering and soldering on new and improved 20000k 3watt leds. I hope this helps anyone who is curious about replacing theirs and wasn't sure about doing it. If you have questions just ask.

Hope you don't mind me bumping the old thread, but love to hear your input on swapping some lens! Was thinking of making the following change. 2x Mars Aqua on a 55g
Abridged Version (for each):
"¢ Ditching 3x 3500k & 3x 7500k on white channel, for 6x 20,000k
"¢ Ditching 6x 460nm on blue channel for 2x 385nm & 4x 415nm

I was considering removing all the 3500k on the ones I'm getting. I don't like the yellow look. I'll probably swap with a combo of 7500k nd 12000k.

The first one i understand (less yellowish look), but why change the blues for violet?

To give more variety in color instead of only 450/460 nm to that channel
Sb reef also had an interesting point of introducing uv , which in return corals develop uv protection coloring
But only considering 2x per light
