View Full Version : 2 photon 16s or 1 photon 50 on 5ft tank

I have been using 2 leds as well as a retro t5 kit over my 5ft mixed reef. one of the leds is a photon 16, the other is a similar type led (evo ts100). I am now considering replacing them with the V2s. I am on the fence if I should get 2 photon 16 V2s or 1 photon 50 V2. the reason I used 2 before and was thinking 2 now is the way I have my rock setup. I have 2 peak/mountains in the tank. one on the left and one on the right, each LED is directly over it. In the middle of the tank I have a low section, there is rock but it only about 6in off the sand. In this area is where I keep my chalices and some acans. I was concerned that adding the 50 which would be a full length LED would blast the middle are with more light and kill the chalices. What do you think?

One V2 50" over a 60" tank that is 20" deep and 24" front to back. BTW, this tank was set up in Sept 2016 so it's just over 6 months old.

Your corals in the valley between the 2 fixtures are already deeper in the water which makes a big change in PAR. I think you are over thinking the situation. One 50" works great. They only reason to go for 2 would be if one has issues (hey, it happens) you still have 1 fixture for over the tank. Or, if you have other back up fixtures, 1 50" looks really clean. I just happen to have 2 because I have 2 tanks. LOL!

Looks great Ron!

Thanks Steve. My old tank leaking and having to be torn down was awful, but the new system looks so much better and I'm very happy with it and the Photon V2 fixtures.

And I just want to help steallife904 to get what is the best fixture for his situation.

i pulled the trigger on the photon 50 V2. Cant wait to set it up... I hope i love it :).

Side note- look out for a sale thread with my old photon 16 (one is 2.5 years old, the other is brand new in box never used). i also have 2 evo ts100s (very similar to photon 16). so 4 total leds will be for sale. if anyone is interested before i list them in a few days shoot me a PM.

Ron: Any particular reason you went with the Photon instead of the Aquasanrise?:confused:

To be perfectly honest, I really hadn't read anything about it. It doesn't seem to have much of a following here at RC compared to the buzz the new Photon V2 got as soon as it was introduced.

The V2 50" was on sale at $610 and the Aquasanrise 48" was $699. The V2 has a better blue to white ratio IMHO. If yo you take the RB, CB and V add them together vs the W it works out to 60B:20W (3:1) for the V2 and 56B:32W (7:4 or roughly 2:1) for the Aquasanrise. I think the 3:1 ratio is much better and even at that, I still run my blue channels a double my white channels. I liked the look of the V2 a bit better and I liked having a dedicated remote rather than an app for a remote.

I don't know if the Aquasanrise can be addressed so each fixture can be run separate from any others. I have 2 of the V2 fixtures and would like to run them with different color mixes, one cool white and one warm white over my display refugium. The V2 has a feature in the remote to add discrete ID's to each fixture, but it doesn't work with the fixture. That was a big disappointment then I found out. I don't know if the Aquasanrise can do that or not.

I realize others may see those features differently. And the fact that the Aquasanrise pucks are easy to swap is a really nice feature. If the V2 had been at the regular retail price of $675 and I were making the decision again, I might very well go with the Aquasanrise. If they can be programmed and run independently, I certainly would have gone with the Aquasanrise. But I didn't give it much consideration at the time.
