Going from leds to t5s mounting height

[Knotyet]

I have 2 ocean revives over my 110 gal tall tank from the water line to the sand bed is about 26 inches or so. Im switching over to t5s. I just ordered a 6 bulb ati fixture. Wondering what height what be be best?

Maybe from 5 to 10 in

Start it up a little higher, but you can lower then down pretty far once you get everything acclimated. I lower my lights down until I am happy with the spill... some of them are pretty close.

I was thinking about starting them around 10 or 12 inches then slowly lowering them my LEDs aren't turned up very high

I keep losing sps everytime I put one in the tank it dies within about 2 weeks. All my parameters are good and no swings so I'm thinking it's the lights that's why I'm going to try t5s.

Phos .1 to .18
Nitrates about 15
Alk stays about 8.2
Cal 420
Mag 1350
Sal 1.025
Temp around 78
Dont know what it could be other than the lights

 

[Cole.mormon]

Try keeping phosphate at about.02to .09 and get nitrates down to 5 or 10.

 

[Cole.mormon]

Try purigen to get rid of dissolved organics or other things also what nutriens do you dose and what filtration do you have

I can never seem to keep my phosphates stable I have a reactor that a run carbon in and whenever I ran it mixed with gfo it would bottom my phosphates out everytime. I have 11 fish in the tank and it's about 10 months old in the beginning I had to dose phosphates Nd nitrates and the corals were growing great now everything has completely stopped for the last couple of months. I was using nopox for about the last 3 weeks and it was working good but I stopped because I I've came home twice and my skimmer was overflowed out of nowhere

 

[Knotyet]

Idk what to do anymore I've been struggling with the tank for months and just cant figure it out. I just got icp test results too and everything was perfect

The tank will mature with time, a brown coral is better than a dead coral. It has taken me months to peg phosphates at the sps is happy around .10 and 5 nitrates.

Is the coral losing tissue? Turning white?

Personally I would stop GFO and NOPOX and just go back to basics, watch your feeding and ensure your skimmer is working effectively along with weekly water changes

 

[Knotyet]

I had a green tipped birdnest with tissue just flaking off and now I have a milli and tenius that I've had the whole time that are stning. The faded color now turning white at spots

 

[Knotyet]

Lps are doing fine

 

[Bpb]

Have you measured par? And are you frequently changing your spectrum and intensity? It has been well established those lights can grow sps if used correctly. If the lights are indeed the culprit, I’d sooner say it is in the application of the product. Not the product itself

Did you start with dry or live rock? Also switched to a sunpower thinking that was the issue and it was not.

 

[Knotyet]

I started the tank with all live rock
