Best settings for hydra 64 HD

[morrisDR]

Hey I have two Hydra 64 HD lights for 2,5 years now. So far I am really happy with it in terms of coloration. I bought a purple clam that turned blue in 2 days with these lights. I also run a really high kh of 10.5 but corals are still looking great. There is only one problem. The growth! I was wondering what spectrum and light schedules you guys use.


My tank is a little under 100 gallons
Size: 125x40x40

Here is mine (the screenshot was from 2 years ago my reds and greens is now at 0% haven't changed anything since):

 

[X-37B]

This was 2 16hds.
I got good growth with
First 4 100%
Last 4 50%
1hr ramp up/down
10hrs peak.
Start and at 10 months when I broke it down. 20g

Thank you looks fantastic!

Anyone else with great results?

This is that I run on my reefer 350 (3x hydra 32)

I absolutely love my color spectrum. It’s juuust blue enough to make colors pop with next to no washed out windex look. I like to be able to clearly see the natural colors of the fish so overly blue is a no no for me.

My coral coloration is great. Growth on all types of montipora is fantastic in my tank but I find growth rates of acros to be lacking.

I believe the Hydra’s aren’t great for coverage. To mitigate that I’ve got 2 Quanta Pro (reef crest daylight) arriving today.

Oh, forgot to mention run the 3dReefing diffusers on all my hydras. I think every Hydra owner should be. It eliminates disco ball effect and helps with the spread of the light a lot over stock configuration

Nice Programm aswell. Can't afford some extra lights sadly so I will place across on the best spots possible

Just to confirm, are you running them at the recommended mounting height of 12-14” off the top of the water?

Sadly al little lower. It can't be placed higher. My corals are still doing fine to be honest but could receive some more light.
