Frag tank On the same system as display

[TUSI]

Does most reefers have there frag tanks connected with the display tank? If so how are the frags doing in frag tank compared to corals in display? Lighting period in frag tank is 10hrs per day vs 12hrs in my display.
I have a frag tank connected to my display, the only difference is my display have MH and T5 for lighting and my frag tank have only T5. What I have noticed is that corals in my frag tank do not color up the same as matter of fact they loose color or get much darker in color. I like to hear some opinions as what could be the reason.

If they share the same water, the only difference is the lighting and placement. What size frag tank, what is the fixture, how many bulbs, what colors are the bulbs, and how old are the bulbs

Mh gives off certain wavelengths ( infer red, uv ) that other light types don’t. This would have to be my guess

Water quality will obviously be the same, but there are things beyond lighting that could vary. Temperature, flow ...... lack of fish. For example, I get more polyp extension on the corals in my frag tank because there are no nippers.

What’s the time frame that you notice the changes? How old are the T5 bulbs? I forgot when I stopped by how high the lights were off the top of the frag tank. What’s the flow in the frag tank?

I have a 40b connect my 120dt and 40b simp. It works well for me. I run radions and t5 in the dt and reefbreeder and t5 on the frag. No real difference.

We just have to determine what’s different between the 2 tanks because the chemistry aspect is the same.

Lighting, flow

My guess would be the MH is the difference. Also which T5 bulbs are you using? Do you k is what par they are getting in the frag tank?

It would be interesting to put a frag back into your DT and see if the colors return back to normal.

All good points.
Frag tank is 36"x12"x24"
Light is an aqua medic 8 bulb fixture
I was using 2 actinic, 1 Fiji red, 3 coral plus and 2 blue plus.
Just changed them to 6 blue plus and 2 coral plus
Light cycle is 4 blue plus 10 hrs and 2 blue plus with 2 coral plus for 4 hrs while others are on too.
3 fish in frag tank
Mp10 for flow and eheim pump for circulation.

Once I was told by a hobbies that I keep my lights on to long in my frag tank, which I'm having a difficulty understanding.

Here are pictures of my display (215g) and frag tank (50g).

Display has an ATI T5 setup, frag tank is lit with Ocean Revive LEDs.

Other than differences between how they look under each type of lighting, health is generally the same. Only differences I notice is slightly more shadowing with the LEDs on my acros and its much easier to take pictures of the display than the frag tank.

On my old setup tank (215g), I had attached my frag swap tank (12g) and used it temporarily as a frag tank. Similar set up except there was a much lower volume of water and very shallow which made flow options very limited. In that setup, I was running the same Ocean Revive LEDs on both the display and the frag tank. My acros looked terrible, browned out mostly, algae grew everywhere, and I couldn't figure out why it never worked out.

Hindsight observations, I blame it all entirely on flow. It was so shallow that all I could do was setup a circular flow and it kept detritus within the system. So basically it was a detritus dump for my whole system and eventually the corals looked that way too.

The frag swap tank that I used as a frag tank was similar to this one.

Looks like we have a winner lol.

Is there a reason for the sand bed in the frag tank

Is there a reason for the sand bed in the frag tank

No, just prefer it over bare glass. Plus it allows me to keep a melanarus wrasse in there to pick at frags all day.

 

[BoomCorals]

It’s going to be lighting or flow. I don’t think the T5 vs T5/mh is the cause. But placement and par.

 

[TUSI]

I am starting to think it's flow. The lights also but I changed lights and some corals are showing better signs of growth
