Hydra 26HD power level

[twilliard]

To me montiporas are tricky and finicky
I had many discussions with Scott when he worked at Unique Corals about these guys.

So what's their deal as far as lighting goes? Less light? Or, is it more of a light plus nutrients thing? I know that back when they were thriving in my tank, I was lazy with water changes, had a lot of algae, and my light was a diy light made with 3w cree leds.

Now that I have little algae and a hydra26HD, they are bleaching.

bleaching is both light and nutrients ime.

either up the nutrients or down the lighting.
a common issue dosing nitrogen is that po4 is driven down to absolute 0.

i personally dose po4 very rarely for this reason alone.

i wouldnt suggest this kind of thing unless you are fully aware of what you are doing.

It's a tough call.
Too much light for the available nutrients is what it sounds like for that specific coral.

Agree there... I don't have very high nutrients (5ppm NO3 and 0 PO4) so I keep my Alk pretty nominal (8.5 dKH) and the lights pretty low I suppose as well.

I have quite a number of montis and they all do really well.

Ah I forgot about nitrates pushing down phosphates. That may be why I don't see any. I'll see how rhe frozen food does the tank. I don't rinse, just toss a piece of cube in there. Just made the switch yesterday, so maybe I'll see some results in a few days. I'll hold my tank lights at 35 watts peak and see how things behave with the added nutrients.

Russ,
Which light are you using?

What I'm really getting at with this thread is how much wattage should I be working towards. My acros look happy, but montiporas are losing color. Not sure if it's too much light or too little nutrients. My nitrates are around 5ppm but phosphates,according to Hanna, are 0. Montiporas are fading out, even on the bottom and off to the side, while acros are coloring up and encrusting.

Matt

hanna phosphate test has two types, the low and high range... use low range, it reads from 0.00 to 4.00, the high range reads 0-20 i think.

I run two Hydra TwentySix HD LED's on my mixed reef 120 specs being the following 48''x24''x24'' and currently have my 2 fixtures mounted 10'' above the water line.
Scroll all the way down to see where I keep my settings at. I run them with a 2hr ramp up and 2 hr ramp down w/ my Royal Blue & Violet @ 1% for my moonlights lights from 11:00 pm till 8 am, then they are totally off until ramp up time which starts @ 2 pm. Last but not least, I am going to be adding a Reefbrite 50/50 Lumi Lite Strip LED across the front of my tank to add some extra pop.

Been away for awhile after hurricane hermine crashed my tank. Back for a reboot!

Anyways, still trying to figure this light out. When I see these PAR charts, are they assuming maximum output? All channels on over drive? If so, ick. I'm running the ab+ schedule now, which is blues at 90% and the rest at 35%. Wonder what PAR that would be? From the charts, this light is pretty weak as far as PAR goes.

dang sorry to hear about the tank

running two 26HD's over a 36x24x20 about 9 inches off the water.

For 30 gallon shallow frag tank acro heavy I have 26hd hanging about 15" above water and white uv and violet maxing at 35 green and red at 25 and both blues maxing at 55 percent. This gives a wattage of about 45 when maxed if my memory serves. Just bought par meter and have not checked it yet but will post readings later.

Very blue heavy, mixed reef. Max at 84watts 10" awl, 2x hydra 26 hd

I'm especially interested in your par readings. How are your acroporas doing? I'm surprised you just need one light for a 30g and you have it 15" awl.

Here is my update Light Sch for my pair of Hydra Twenty Six HD LED's. Keeping all Acros and Monit's about 8'' -10'' from the water line and my light sit about another 8'' from the water and my SPS corals are doing great! My Ramp up time is 1hr and a half starting at 1:00 pm and ramp down time start's @ 9:30 PM. Also, I just grabbed a Neptune DOS system for Automatated water changes only. I have it setup to take out 1.5 gallons of OSW and replace it with 1.5 gallons NSW at the same time every day from 00.00 till 18:00. So my water is constantly doing tiny water changes which are super healthy for your tank and corals.
