Unless you are using it on an air driven skimmer, you don't need that air pump. Or that bubble bar. Take them back and get your money back. They won't do hardly anything for oxygenation AND will give you "salt creep" everywhere from the bubbles popping and causing tiny sprays of saltwater. You will be much better off getting a good powerhead to increase circulation in the tank (VERY important for filtration....speaking of which, are you using live rock for filtration?)
Been gathering info for a while now. Thanks to the fellow redditors for all the help and advice, especially K_draggon, LikeMaugal, Pllatium, Baboa, Tropheusdubosi, medym, and ispringer.
You guys gave me a lot of great advice that helped me put this together, along with information from nano-reef and ReefCentral
Tank is a 20 gal high spare tank I had. 50w heater, Light set up is Nova Extreme T5, pump is Hydor 425, Thermometer is Aqueon Coralife
The 2 larger rocks in the picture, was 1 large 11lb rock, smashed into 2 base pieces, picked up from Absolutely Fish in NJ
The rest of the rock was purchased from Gulf Live Rock
Tank was set up on saturday 2/25/12, which is the cloudy pictures. Tank finally settled around tuesday. Rock came in last night. Sadly a lot of the stuff didnt make the 2 day trip, but Im sure more stuff will appear soon.
First water change is scheduled tonight, as Ive noticed salinity has dropped to about 1.0 and Im told to keep it around 1.01-.02.
HOB filter is an AC70 which is getting El Fabs 'fuge mod in the next week or so.
Only signs of life so far are a sand trigger, about 4-5 bristle worms, which after researching more are "Fire bristle worms" And i read they are the worst kind and dangerous, So i will be plucking them out at night as I see them. And a few dozen peanut worms in the rocks. There was a small snail, and crab, that I found that didnt make the trip , which would of been nice to have.
I gave about 3 cups of sand to a friend, whos going to put it in his tank for a few weeks, and then give back to me, so I can get some of his copipods and other stuff he has living in his sand, and to help cycle my tank quicker.
Try one of these. Pretty cheap and helped me out a ton. This worked on my 75g.
It's typically called a wave maker or circulation pump. This is the one in my video. I went through a few different brands before this one, and in comparison it's been really reliable. Helps keep water flowing and debris off the surface of the substrate.
I don’t think those exist, I’ve had a variety of air pumps and none of them were completely silent. I’ve padded them with towels and foam to lessen the noise but the good news is that if it’s for an air stone, you don’t really need one. Water circulation and breaking the surface of the water increases oxygen levels too so if you bought a water circulator and aim it at the surface of the water then you’d be good.
I have this one. It works great and it’s silent

If the air pump is for your filter then change the type of filter that you’re using. External or internal canisters are silent.
I recently started a 10g after doing a crapload of research. This is what I ended up with:
A lot of folks I talked to said the live rock and water changes would provide sufficient filtration, but I do enjoy the extra water clarity from having carbon and purigen in the filter.
You'll need a circulation pump as well, you have to have good water flow through your LR - it's your biological filtration. A 425 gph Koralia Nano would be sufficient. Or you could go cheaper I have two 800 gph circulation pumps off eBay and they're solid. Probably saved $50 going with them, and it's just hard to justify the money on something so simple. Even if these br
There's a lot of fish you can go with. Browse through this and this. Just no damsels - I don't know why they recommend damsels as a beginner fish. They're hardy and all, and I guess if you were just going to have 1 fish they can be nice.
I like gobys, firefish, and basslets for that size tank. I just added a royal gramma basslet to my 72 FOWLR - here's a pic, it would do okay in a 29g. Avoid dwarf angels, they're finnicky, a lot of blennies don't do well in a tank that isn't mature (dragonetts). Cardinalfish are okay.
That was there when I bought the tank, I just never took it off. I have another thermometer on a suction cup mixed in with all the other equipment. I used live sand and rock to get it cycled. 6 inches of water, sand, rest of the water, rock. Cleanup crew went in after 2 weeks, fish went in a week later. It has a Marineland Penguin Biowheel 200 for the filter, nothing fancy. The powerhead was a pretty cool find. Here it is Works pretty good on only 3-4w of power. Well see how well it holds up.
I've never had a problem with the Hydor Koralia power heads over the years.
Replying to both of you here - I'm about 5 days planted, so I can't tell yet where any stagnant areas are. I'll keep an eye out - I do have my pH meter and drop checker on the far right front and it's reading perfectly. I know I have current because of some of the debris that's floated up and is moving around. I'll wait to decide if I need one. I'm going to end up with a jungle, so a current will be pretty much required. I'm thinking about this one because it's small.
You don't NEED one, but I'd suggest this if you do plan to get one.
