If you are going for PAR only the Aquablue is a good choice. Using the clip to measure the distance from the lamp to the reflector would be good cause I aint gotta clue about that.

If you are overdriving 80 watt lamps I would say most SPS would be good 16" (12" of water 4" of air)down for sure and montis a bit lower.

Thanks Grim, I think that is where I was off a bit. The bulbs are 9" above the water (in the ligthing rack with the MHs) and the corals were about 9" down below the water line. So I either need to lower the lamps at least 2" or raise the corals that much. Unfortunately neither of those is an option, due to structural reasons and the door that swings open to allow access to the top of the tank. Any other ideas about how to overcome this "little" problem ? Would putting two 3' bulbs give better penetration ? (or one 3' over the particular corals ?). I am trying to take on the mindest of lighting the rocakwork/corals and not just lighting the tank.

Thanks again

thanx....Do you think saving the extra money compensates for the fact that it's a tad underdriven.

Probably. Especially if you use it for actinics.

How about mounting the T5's to a thin piece of wood and hang them from chains.

 

[barjam]

If wood ain't your thing Lowes/Home Depot sell aluminum pretty cheap, you can make frames and mounts pretty easy.

 

[The Grim Reefer]

Theres also square PVC channeling that would work but I am not sure where to get it.

Hey Grim,

I currently have a 4 x 54 Tek retrofit with SLR reflectors over my 60 gallon SPS tank. A couple of weeks ago I asked you how should I upgrade my lighting and you suggested to get 2 more bulbs instead of overdriving the 4 that I have right now.

Anyway, I was wondering what bulbs would you recommend that would work with the ones that currently have which are:

- ATI Sun Pro
- ATI Blue Plus
- ATI Aquablue Special
- UV Super Actinic

Thanks a lot!

we have a full aluminum lighting rack that is on a double motion track. We can move it left or right to remove it from over the tank (for maintenance) and it also moves front to back when we feel like hooking up our light mover. So aluminum is my thing (there is no wood over our tank).

I was actually planning to use coated chains to hang the 1" sqaure stock that the refelctors and endcaps mount to but here is the rub: We have a mesh top over top of our tank. I have a latch system where I can open it from tne front (like a lid) for access to the tank w/o needing to completely remove the screen (the tank foorprint is 4' X 6.5"... that is not the kind of screen you want to be moving more than needed). When I "open" the screen from the front it is just below where the lamps are now, so there is not much more distance that I could lower them. I really only need to light a single 2' rock, so I thought an overdriven 2' or 3' bulb might work for just a little better penetration (and with a 3' one arriving tomorrow from Reef Geek, that was going to be my first try).

Thanks for the suggestions, any more to add (with the new data I provided) ?

Wish me luck

 

[The Grim Reefer]

I would add a Blue Plus and GE 6500K Daylight. Should keep you with about the same look you have now.

So get creative. Set up a pully system that will Raise the T5's as you lift the screen If you couldhange the T5's just have hooks or something to hold them up while you access the tank.

 

[Sparkss]

I think that might be my only option. Thanks Grim (and everyone else that chimed in ).

Thanks for your response Grim. I was thinking that I would like to pop up my red and yellow corals a little.

Should I still get the bulbs that you recommended?

 

[The Grim Reefer]

You could try the new ATI pro Color lamp. That will pop reds really good, should get yellows too.

That sounds good, now I have:

- ATI Sun Pro
- ATI Blue Plus
- ATI Aquablue Special
- UV Super Actinic
- ATI Pro Color

What would you pick for the 6th bulb?

 

[The Grim Reefer]

Another blue plus

 

[carlos_fb]

Got it, thanks a lot Grim, you rock!

Grim thanks for your last responseabout my 75. I have another question concering another tank though. I've built a small acrylic tank 2'x 1'x 6" for frag grow out with a standpipe running to a larger rubbermade sump for increased stability. I have a 2 X24 watt t-5 retro with icecap reflectors. I'm not looking to maximize growth at color's expense, but instead like good color with acceptable growth. Any suggestions for just the 2 bulb setup and how high do youthink I should have the bulbs from the water surface. The racks for the frags will be 1 inch off the bottom, and I can use acrylic or screen to shield some light on lower light corals. Thanks Bill.

 

[witelytr]

grim,

I have taken your suggestion on the 4x39watt for my 30g and was wondering what would be back draw to having a the lichts approx 7" from the water surface to 4". the reason I ask this is that I am trying to make a fixture from wood and it will not have hinges. For maintenance reasons I would like a little more clearance.

4 lamps in each fixture should be plenty. I'd probably do a UVL Aquasun, 2 Blue Pluses and a Super actinic in each set so you can have a blue plus and super actinic for Dusk/Dawn in each.

Many thanks for the suggestions. I'll let you know how it looks - long about January or so!

[The Grim Reefer]

I'd say the lamps could be up to six inches off the water. For lamps do a UVL Aquasun and a ATI Blue Plus. That is gonna give your frags all the spectrum they need for growth and color.

[The Grim Reefer]

Having the light 7 inches above the water will lower the amount of light making it to the bottom of the tank quite a bit. If you are doing all SPS it might be an issue but for a mixed tank it probably not be a big deal.
