Which MH/T5 combo for growth and color

[biecacka]

A guy local to me had a store that closed. Was extra inventory.

Phoenix or Ushio 14 k would.me.my bulb of choice for good colors and growth. If u need more growth then maybe a 10-12 K bulb would be best

Holy smokes! That is some mad growth! I assume you run a calcium reactor too?

I just dose 2 part and 15 gallon water changes every week on Friday. I was pretty surprised when I was looking at the pics.

Do you guys think 20k produces slower growth than 14k?

 

[Broadfield]

I'm thinking that even running all 17.5k Giesemann MH would give you what you want. The lineup of Giesemann bulbs always seem to have a crisp white. At one point or another, I have ran the 14.5k, 17.5k and 21k on my tank... along with Giesemann Actinic Blue T5s. I am currently running the Radium 20k with the Actinic Blue T5s.... but I don't run them all at once per say.

 

[Black Pearl]

yes, I've been running the T5s fro 2 hours before the MH come on and 2 hours after they go off the reefbrites are the first on and last off. once I get the new bulbs I'll probably change this arrangement and run the T5s longer, but then again with the 800W of 14K and 400W Radium they may not need any help except for viewing time

The lower the kelvin the more PAR is my understanding, like I stated earlier, I had read a lot about the Aquaconnect 10k and that it was the bulb of choice for fantastic growth

Giesemann MH are like gold a bit expensive even at 15% discount, but I have heard that they last longer. If that is true it might justify the cost

Maybe in metal halide but not t5, atis blue plus is their highest par bulb I believe.

I probably should have been lol, I'm a little tired. With all the blue light going around these days there is a lot of debate on this topic across all types of lighting. I'm always curious to hear people's opinions/experiences. Watch tulio del aquilas (spelling?) talk on lighting from macna, he'll make you even more confused. Basically explains how kelvin means nothing for us and that two completely different light sources could have the same kelvin rating, or something like that. Interesting talk but just kind of went in circles.

Haha yup. It was a great talk, and the guy clearly knows his stuff, but it didn't really have structure. A lot of interesting info for sure though. I kept waiting for him to bring it all together somehow.......but nah, mic drop.

I've been experimenting with Reefbrites Twin-Arc. Has a 10k and a 20k lamp in them. I have it on 10k during the mid day while I'm at work and then later on it switches to 20k for me to look at.

Sweet bulbs, my lfs runs those + reefbrites and I love how that tank looks. Great growth n coloration as well.

 

[Black Pearl]

Two Radium 20k one Ushio 14k
Four ATI blue plus

Love the look of the tank now, colors appear to have more pop, water looks clear instead of blue
