Hello

Hey Jeffkroll look at me now!:rolleyes:



This might sound strange.....but apparently it isn't something new. I stumbled upon others who have been using this radion for the planted tank.Aquascaping with a shallow aquarium | Features | Practical Fishkeeping and here Ecotech Marine Radion XR30w Pro -- Guitarfish
So the question arises why not.
Given the Radions exceptional controllability and power its seems to be feasible.
Using this radion par calculator AquaticLog EcoTech Radion PAR Calculatoreven at using just the whites, red, green, and a bit of blue, as indicated in the first article the power is astounding. I also think that the colour is exceptional.
Aside from price what am I missing. By the way I have a big foot print to cover 60 inches long by 36 inches wide.....why did I buy such a big tank.


Thanks David

David, I wrote the article in the Guitarfish link you referenced. The Radion gives a ton of features and PAR. I get some of the reddest purples/reds in the tank with the Radion than any of the other tanks I keep.

That said, there are some notable drawbacks:

1. Spotlight: Since the Radion is a puck-based LED fixture, the areas directly under the light are very well lit, but the intensity drops off significantly as you move outward from the center. Unless all your scapes are center mounds, I'd recommend 1 fixture for every 24" of width of tank.

2. Color: To help compensate for the above, I find myself wanting to maximize PAR output. In order to achieve this, I have to add more blue light than I really want to. This results in much less pleasing color casting.

3. Fan / hanging: Not necessarily a drawback, but you do need to mount this light overhead, and note that it does have a fan. It's not super loud, but it does collect dust and any mechanical parts like this will wear out over time.

4. Computer control: While the flexibility is nice, without the extra accessory, you have a physically connect a laptop via USB. For things like daylight savings changes, it's far easier to do that twice a year on my other fixtures, than to fire up the laptop, connect, reinstall the radion software, etc...

For me, for the same money (or less), I've leaned toward BuildMyLED fixtures with a controller. It address the issues I list above, produces tons of light, and still has a decent amount of functionality with the controller. Of course, much of the above is circumstance and preference, so YMMV.

Wow pretty cool article.....neat that you wrote it. Really $1000 to cover 2 foot squared yikes! Yup I would need 4......not going to happen!


Ive had bad luck with BML not going there again.


Ok back to research.:nerd:


Thanks David

I did contact them and they suggested that I needed two fixtures for coverage. I was surprised that one wouldn't be sufficient.

Which did you contact?
As far as the Radions go.. the xr-30 is really reef centric as to spectrum..lots of wasted LED's really..





Though it is a personal choice, I find nothing really appealing about that color tank..

a bunch of FW 15's are better..

note the wall splash color..

Oh I. Was referring to reef breeders saying that I would need two fixtures.......is there any available par data for the xr15fw?

you will need 2 w/ any light since you are 3ft wide..


Actually w/ the Refbreeders you would get about full coverage at hanging the RB 12'- 18" above the water line..
i don't think Logan really "knows" fw..

It won't be sig. different than a reef version..
Good to know Jeff I think the xr15 comes in at about 825? Just below the light.....so the fw version should be adequate. I put in a request with ecotech inquiring about par levels and adequate coverage for my tank. Will share the findings here. The Radions are about $100 less each than my Kessils are on my 125......The Kessils have great spread but I'm not too fussy on their colour and lack of tunability ......ah no pun intended! 😊Oh BTW I trolled and found an old posting about you and Kessils.....
Really made.me laugh 😂

THANKS FOR ALL YOUR INPUT JEFFKROL I SINCERELY APPRECITE IT

Ok received contact back from Ecotech and they suggested that I use the xr30wpro!


I then informed them once again that this was a planted aquarium and not a reef. I thought the term planted aquarium in my first email would have sufficed. They said that due to the size of my tank that they would suggest that I not use the xr15fw but use two xr'30 instead. They also said that the spectrums would be suitable. Yup reef centric that is for sure.
They ignored the request for par data on the xr15fw and the suggestion as to how many units to use.


Emailed them again very nicely asking for answers to the questions I had asked.:wink2:

David,

We do not have PAR ratings for XR15FW Radions.

Thank You!

Yup that is some serious spotlighting dropoff.....but as he noted it is expected with this type of fixture.

Thanks

there is the 120 degree lensing.. Putting 3-4 about 1.5ft above the water line should give you pretty good overall coverage and fair fw PAR but you didn't state (or I'm too lazy to find it) how deep the tank is.

why did I buy such a big tank.
Yea, was wondering that myself . too much discretionary income.. ;)

anyways, I still think one reefbreeders Photon 48 long is adequate...Say 18" above the water line and a 24" deep tank puts you at about say 38" from source to floor..
Guesstimating about 100PAR at 30".. You should still be around 50 at the floor.. Certainly not "reef good" numbers but...................

Hey jeffkrol

Tank is 27" deep so with 2-3" of substrate that should give me 24" from top to bottom........the tank Also has a thick top trim about 11/2" so I don't have to fill it to the top so let's just call the water depth 23".
This was going to be a reef tank.......but my first love is the planted......so much more forgiving and not high strung like a reef tank seems......plus making all that dammed rodi water!
Every tank I've had had gotten bigger and bigger so I though just buy the one you dreamed about and sell the rest and that's what I did. I wish I had that much disposable income...but really this has been a very long term project.

So.....and I know that this is only your opinion.....and that u aren't responsible for the out come but based upon your observations and knowledge 4 xr15fw should fit the bill for fairly even coverage and a bottom most par of about 80 micro mols?

A local fish store has one set up so I'm going to be able to take a closer look. I'm particularly interested in what the colours will actually look like in tank in person.

Thanks david

You have one every 12" on center.. Should be plenty of light for anything.
you could even do some creative spacing.. stagger each front back..

At short distances LED falloff is fairly linear.. BUT eventually it starts to behave more logarithmic.
not sure I'd guarantee 80 w/ out a tad compromise on the height (lower than full coverage at the water line).

Get a cheap lux meter or use a camera phone app to at least get a lux reading at like 4ft free air would help..

got to admit big tanks reinforce my bias against puck style lights though..;)
