Tell me if I am on the right track (Planning on 29g setup)

Hi everyone. I've been lurking on this forum and others for quite a while, anticipating setting up a reef tank. We (my wife and I) already have a 90 gallon Mbuna cichlid tank, and a 55 gallon planted community tank (running co2 and 2 110w VHOs) that are well established, and running great. We've been wanting to do a smaller reef tank for a long time, but didn't want to rush into it. After about six months of reading a lot of good info (and a LOT of confusing info), I think we're ready to to give it a shot. We bought a 29 gallon tank and stand from a friend of ours for a great price, and this is what I was planning on doing for the setup:


29 gallon tank. back drilled for overflow (1" hole maybe)
10 gallon homemade refugium in stand
Coralife super skimmer 65 gallon version (or other, recommended skimmer)
Mag5 pump to return sump water to tank
Closed loop SCWD powered by Mag7 (Or two SCWDs [one high one low] powered by a MD18 I have lying around)
250W 14,000K HQI with cold cathode night lighting
2" sandbed and 38-44lbs live rock in main tank
5"-6" sandbed in refugium with chaetomorpha and liverock rubble
Heater will be in the refugium, with fans in canopy, and over fuge

Once everything got up and running, and cycled, the plan was to add a cleanup crew of various snails, crabs, shrimp, and stars. Once everything has been running for a while, we'll decide on livestock, but we planned on having softies, sps, maxima clam, an anenome, black and white percula clown, and possibly a watcman or other gobie.

Any and all advice is welcome and wanted. I know that the MD18 would probably be too much flow for the tank, but I was thinking of using two SCWDs. One having it's two outlets near the top of the tank, and one having spray bar-like outlets going horizontally across the tank, behind the live rock. The upper outlets would create a more directed, powerful current. Where the lower, spray bars would make more gentle current to get water everywhere, all around the live rock. I figured the MD18 would probably just move too much water for the tank, but since I had it lying around, I figured I'd ask. If a Mag7 is enough flow, I'll be glad to stick with that, I just tend to overdo things.


So please, tell me, what do you think.

The 1" overflow is plenty for that sort of flow. You may want to consider a bigger fuge if at all possible...say a 15 gallon or even a 20L if it'll fit. I would skip the sand bed in the refugium...everyone I know of that put sand in their fuge regretted it. Instead, try a RDSB...that is, a 5 gallon bucket that is remotely installed... http://reefcentral.com/forums/showthrea ... genumber=1 (very long thread but you will get the idea in the first couple pages. Also as far as fuges go, I would suggest looking here http://www.reefcentral.com/forums/showt ... did=462212 and here http://www.melevsreef.com/ . The cheato is great... go with the light from Walmart that is made by Lights Of America... 30 watts 6,500k screw-in, $8.99 (here is a pic of mine http://i28.photobucket.com/albums/c247/ ... light2.jpg ).

I dont have experience with the Coralife skimmer, but I know that the Aqua-C remora is tried and true and is great. Also, ASM makes in-sump skimmers that are equal to the larger Aqua-C's but cost much less... http://www.asmskimmer.com/catalog/produ ... 404da44168 .

Instead of the sand bed in the fuge, you could do a 4"-5" sand bed in the main tank because of the height of the 29 gallon. I would avoid stars as they usually starve in mini reefs. Also, take care in mixing softies and SPS as they require different care.

As far as a return goes, try a manifold. This has allowed me to have around 650 GPH returning to my 20L without any problems... http://s28.photobucket.com/albums/c247/ ... mbing2.jpg , http://s28.photobucket.com/albums/c247/ ... stRun3.jpg . It looks rather intrusive and bulky, but i never notice it... this is all you see from the front... http://s28.photobucket.com/albums/c247/ ... -17-06.jpg

For a closed loop, the Mag 7 should be enough...it all depends on the target flow you are going for... SPS tanks can go as high as 100x turnover per hour.

I dont know...I hope i was of some help.

Feel free to ask as many questions as you need to.

And welcome! :welcome

:welcome to nanotank.
Jesse has pretty much covered everything I was going to say. I do want to second that ASM skimmer, they have a model out (Mini G?) that sounds perfect for your tank. I do know their bigger models are great and would expect nothing different from their newest addition to the line-up.

Thanks everyone. I have a few more questions. First off, Eddy, what kind of fish is that in your avatar? It looks like a goby of some sort, but I've never seen one like that before. It's beautiful!

Jesse, I've read to page 18 of the RDSB thread so far, and I'm totally sold on it. Here is what I was thinking for that and the fuge: Have the tank drain into an empty bucket containing only the skimmer. Have the skimmer bucket drain into a 10g glass bare bottom refugium rolling around chaeto. Have the fuge drain into a 5g bucket for the RDSB. Have that drain into a 10g glass tank containing bubble trap and return pump.

For the main tank's circulation, this is what I had in mind: (Please forgive the crappy MSpaint pic)

Front view of manifold

Back view of manifold

The spray bars toward the bottom would disperse water over a greater area, getting fresh water to all the nooks and crannies of the LR. The upper nozzles would create greater directional flow throughout the front area of the tank.

I know high flow is a good thing in an SPS only tank, but would running 1,300gph in a 29g be too much for LPS, or zoas, or an anenome? I want to put the right sized pump on the manifold, but if more is better, then I'd be glad to use the MD18. Thanks again.

I love the setup! Can't answer your questions as I no nothing of SPS. But I have an idea for your "sump" setup. How about the water coming from your tank split into a T and have one section go over a RDSB bucket and the other into a skimmer but and have both of those drain into a single 20g long tank that has your media slots/macro/bubble trap/return pump? You could have your two buckets above the 20g and that way save a bit of space and still have room for a bucket for ATO water. Just an idea.

Tim,

The reason I had planned on everything being in series, was because people in the RDSB had said that it would be best to have as clean of water going through the RDSB as possible. Unfortuneatly, I wouldn't be able to fit a 20g long tank under my stand. The interior dimensions of the stand are 27.5"L x 10"D x 27ish"H. I'm either going to have to build a new stand, or just have some equipment behind it. Maybe build a separate box to hold all the plumbing.
