Frag tank advice..

Frag tank advice..

Hi guys,

My two d120's are working great over my 4ft tank. I might swap a few blues to uv yet tho..

Anyhow, I have emptied my 2ft / 60 litre tropical tank and I am going to make it into a small frag tank.
Would a single Full Spectrum d120 be ideal for this, or would that be overkill? Seem diy kits and nano light but d120 is actually cheaper (maybe runit at 30%?)

(On a side note, small frag tank: will be getting some live rock in, BUT sand or no sand?!...!):uhoh3:

FWIW I have one running on a 24 gal nano cube frag tank...18x18" up to 55% now after about 6-7 months.
I have no sand in display but I do have sand in the fuge.

Hi all, brand new to the reefing hobby. been looking through the forumn and there is just so much information regarding led lighting its all hard to take in. I found a good deal on some full spectrum fully dimmable 120W led panels. I have a 72 inch 125 gallon tank. hanging from the cieling is not an option so they will be going in a canopy. Ive read the threads on the fire risks and stuff but my main question is....I dont plan on having my tank with hundreds of pounds of rock and coral in it. maby a medium load. Not lookin for the best thing on the market either. are these lights good for something like that? do they perform well in a canopy that has a good airflow? would 3 panels suffice? thanks!:beer:

We should try to not post direct links I think that was One of the issues with the first thread getting closed FWIW..

I am planning a 8'x18"x18" what would be a good inexpensive fixture? Seems like the rb is made for wider tanks. I don't need tighter optics for my depth. They should offer a model the has less LEDs wide and more long. Ideas welcome.

I wish somebody who actually knows what the rules are would post here so this kind of worry doesn't keep popping up. Hey! Are there any MODERATORS out there who can explain the rules on outside links! Please. :idea:

The farthest you can get width wise is about 24", if anything, you need more rows width wise. I would use 4 fixtures with 120 degree optics, at about 5" off the water to cover your tank.

hey reef breeders. they coming out with a new lilght.. hear rummors.. I know it was delayed to redesign. do i have this right. ?

Yes, we are in fact coming out with a new light. Our engineer tells us it will be ready for April 1st. Check out hte SuperNova page on our site, and stay tuned.

That is an outstanding setup! 250 PAR at the sand bed at half power? Nice.

Thanks, The lower par numbers were on the corals at the bottom so that's about 3-4" off the sand, still really good numbers.

I had a PM about the bulb layout but I can't reply without 10 post so I'll post it here, hopefully they will see it or I'll post a couple more times so I can respond lol

Please color code it, those are hard to read, lol. I would skip the 10ks and 6500ks, and go with nuetrals. Swap the 400nm for 430nm

Thanks for the advice, I took the lazy route and went with the layout some other guys in our local club came up with in a group buy.

That is the page that was sent to me, it would be nice to see the colors

How many of your fixtures would you say for a265 gallon 7 ft x 30"deep?

I have a IT 2080 light and need to change some of the lights. It came with some of the white on the blue channel in one corner so I need to change the position of six of the LEDS. What do I need to do to change them? Thanks for any help you can give.

You need a soldering iron, thermal paste, and some 1mm solder. A pair of tweezers helps for placing the diodes.

how wide? and what kind of corals do you have?

Ok what is the thermal paste for?

 

[hillscp]

It creates a heat transfer connection for the led. It's the same as the paste that sticks a computer CPU to the heat sync.

 

[john reefer]

I have some extra leds from when I bought the light. Just looked at one paste under the metal on the back. I"m fine w/ the ones I'm moving, but the new ones how do I know + - or does it matter? If I need to test them how many volts are they? Thanks a lot! I feel much more comfortable moving my lights to the right channels now.

 

[hillscp]

Yes the + - matters. I have not seen those emitters but I have strung LEDs before. Have you sent RB an email? They should be able to answer. Most stars have plus minus clearly marked and idk if they are in series or parallel.
