My sps is dying?

I have a 65 gallon tank that i upgraded from my 20 gallon. It has been running for 4 months or so now. I have some acropora frags that i put in and the first month they grew a nice base and looked great and now the color is gone and it looks like the tissue is degrading. Im using a 300 watt led. And it has good flow at around 2400gph in the tank in different directions. The parameters are usuaally stable At...
Ph 8.1
Cal 425
Alk 9dkh
Mag 1350
Nitrate 5.0
P04. 0
i have a bubble mag curve 5 skimmer. And running a fuge with cheato and a gfo reactor with 1 cup of gfo. Every time i test p04 its completely 0 but im too afraid to turn it off because i dont want algea. All tests are either red sea or salfiert btw. And reef crystals salt with a 6gallon weekly water change wvery sunday. I dose 6ml a day of 2 part esv cal and alk to keep it in check. I have a 2 monticaps that look great but grow very slow if not at all. And the green slimer and the other mystery acro thats losing color and not growing anymore at all. Idk if its because i have no phospate or something complety different. I need so advice on what to do.

And i have 4 fish
1 small tomato clown
2 chromis (small)
1 kole tang (maybe 4 inches long)
I feed once a day and they usually eat it all in 2 minutes
 
Great nickname man...use it with my xbox account,lol

How long are the frags under the leds?
Did you change recently the gfo?
 
I change it every 5 weeks and last time was 2 weeks ago. About 7 hours a day. At first when i got them i put them at the bottom and it raised them higher every week. They have been at the top for a month now and in the tank for 2 months all together
 
If they were doing better when they were lower it might be the light.Maybe they just need a little more time to acclimate or less %.
If gfo had something to do with the stunted growth you'd probably witness some stn too.Just my humble thoughts
 
They didnt start really growing till they were on the top. I have another piece thats half way down that came off the same frag and its the same.
 
Difficult to say, but having GFO online with such a small bioload in my experience would be counter productive to sps health in many cases. I would consider taking it off line for a few weeks, and see how the sps respond.

You said 300w of LED? On a 65?

What type of light are you using? How high above the tank? Is it attenuated in any way? What is your photoperiod?

Wow that thing looks like a good value. :) are you running them dimmed? I think that is probably too much lighting if so. Difficult to tell though since I don't have any experience with that fixture. Do you have any sort of light meter?

I would be curious to know what the actual power consumption is. Multiplying the rating of the LEDs by their number isn't really accurate.
 
Full power. Its a nice light i had it for 4 months now and everything but the sps is growing i dont have any light meter and these are my first sps so im not sure what is too much or not enough. It say We use 5watt LED chips.It is more brighter than 3W,It can produce more Par Value.*
(2) To ensure its long life span, we drive this light with 490-550mA safe current,The best Par Value Current. Because different color and wavelength led have different voltage and currenty,So the power can reach 121-165W,and the max Physics power can reach 300W,when you run the currenty more than 680mA.
(3) Extra Watt is drived by higher current mean less in growing Coral Reef since PAR value won't increase too much.*
(4)We use Intelligent temperature control system Powersupply.When temperature is higher,the current will be low
 
I have it at full power for it can spread the light to the ends of my tank. Its very spotlight. Im gonna get another one soon for i can run both at 50%
 
I would turn it down. Without a light meter I would be guessing at intensity. But lower light is much less detrimental than is higher light. Turn it down and see if the SPS recovers. Try to get them darker in color.

Damn Chinese instructions. But yeah that's what I mean about the 300watt thing not being accurate.
 
in a normal SPS system for optimal health:

the higher the light intensity-- higher the nutrient load (think BALANCE)

mismatches end up with sps without color or browned up in the latter case

Sure. But browned out is better than bleached out.
 
Yeah its not getting brown its getting more white and it looks like tissue is coming off. And the green slimer is whiter on the side where its facing the light and not growing at all in the 3 months i have had it

What do you think?. Do you think its garbage haha? Ill run it at 55% when i get home for a few weeks and see what happens

No I'm sure its fine. A photon is a photon. I did mean that it seems like a good deal. The main gain you get by spending more on on LED unit is increased control and functionality. That said I think that light uses some unusual brand of LED that I am not familiar with.

Yeah 55% is a good idea.

I will put it this way:
If the actual consumption is ~ 165W then it is equivalent (in consumed power) to a single Radion XR30. It also states the coverage is equivalent 24"X 24". On my 120 SPS tank I run my radions at about 80% at the same height as your light. That is the highest I have gone with them and it took many months of slow incremental increases. I started at 45%.

Remember though that these are two different fixtures; different optics, LEDs, drivers ect. Not a great comparison.
