Thanks for all the info I was just thinking to myself today that I need to find out more about the fuge. I just set up my fist one so I hope all goes well with it.]]> Mon, 18 Aug 2008 17:50:00 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=27220&PID=248525&title=sump-light#248525 <![CDATA[Sump Light.... : Pods live in macroalgae but you...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=27220&PID=248291&title=sump-light#248291 Author: Mark Peterson

Pods live in macroalgae but you can also place some large sand or LR rubble in an area of the Refugium to encourage more bugs.]]> Sat, 16 Aug 2008 12:21:26 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=27220&PID=248291&title=sump-light#248291 <![CDATA[Sump Light.... : Do pods need some live rock in...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=27220&PID=248210&title=sump-light#248210 Author: kdinkel

Do pods need some live rock in my sump? I have a pretty good population down there that I don't want to lose.

Thanks for the help.

In my experience, 3-4" of LS covering the bottom of a Refugium is many times better than LR. The depth can be increased to 6" which will provide more low pH area to dissolve the sand, releasing CaCo3 into the water.

The light on a RDP (Reverse Daylight Photosynthesis) refugium should be very bright, as bright as possible, unless you are going for a Benthic/Sponge Refugium, then the old kitchen light will work just fine so the sponge can grow on the sides and bottom of the LR.

Fluorescent tubes lose most of their power (like about 60%) by a year. For the bright light needed for an RDP Refugium they should be changed before a year is up.

Not to Hijack this, but I am looking to improve the same thing. I have a lot of live rock in my sump/refug. Is it better to have 3-4 inches of sand? Should I go deeper? I have a florescent kitchen light attached to the inside of my stand (mounted on the side above the sump) and the florescent light that I had on a 20 L. It is just the cheapo light that comes on as part of a lid. I think they are T12 or T8 and it is 24". Is that bright enough? Do I need to change the bulbs yearly for here as well?]]> Fri, 15 Aug 2008 14:31:27 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=27220&PID=248163&title=sump-light#248163 <![CDATA[Sump Light.... : I recently asked here for Utah...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=27220&PID=247363&title=sump-light#247363 Author: Mark Peterson

I recently asked here for Utah sand because I don't get to Salt Lake very often and never have time to go out and collect it like I used to. I had more offered to me than I could accept.

I have found that Silica sand will not do the same as Oolitic. It packs too dense creating too much black SO2 sand areas and does not provide any CaCO3 dissolution. I would not use it.

Look at HD for the daylight twist PC bulbs by "N;vision" They even make it easy for you by providing a light color scale right on the package. The "daylight" ones show on the blue side of the scale.

If you can't find any Utah oolitic you can use silica playsand. I got mine from HD at like $3 for a 50 lb bag. It is an acceptable substitute in a fuge - just wash it thoroughly first

Yeah I haven't had a chance to get more sand or rubble yet (Does anyone have any extra)?=) I'll be working on that....

=) but I guess I'll just look for a daylight bulb next time...

From the look of that light in the pic it's either an ordinary incandescent bulb or a soft white bulb. That's the major thing you need to change. Also move the light so that it's more centered over the refugium to take advantage of all the light from the fixture.

That clamp-on fixture works great but the best bulb to use is the highest wattage value "daylight" spiral fluorescent bulb you can find. Don't worry so much about getting the exact one that everyone is saying here. The most important thing is to get a daylight coloration (it's more blue, not soft white) at 65W or better. If my memory serves, it's about $9. Unfortunately many stores carry only the soft white end of the spectrum. It's too yellow, growing more slimey brown algae than the bluer spectrum bulbs. I'd also check other stores thart sell lights, Ace Hardware, Walmart, etc, etc.

Now let's talk about growing a flourishing crop of algae in the refugium.
Algae needs four things: good bright sunlight, high water flow, nutrients from the display tank and room to grow. Harvest it regularly after it covers 90 % of it's avalable space. Harvest it back to about 1/2 of the space so it can grow again. Nutrients include Iron. That's why Miracle Mud a.k.a. "backyard dirt" is useful.

Also, I see a lot of unused space in your refugium. I would place a 3-4" Utah sand bed in there. Few rocks, just sand. If the sand is covered by rocks it can't do it's job. A refugium as tall as yours is an ideal place for that. From the looks of it I'd say it will increase the filtration capacity of your system by ~30% Smile
