  1. Gnome Glass Skimmers

    While having the collection cup at or above water line would solve any siphoning issues, it may also reduce one of the big benefits of having this type of skimmer, which is not having some nasty skimmate cup on the top of your tank for all the world to see. It would be possible to put it behind the tank with the opening at water level, or you could seal the skimmate container, and use another section of tubing to have the vent of the container be above water line. It really should only be an issue when the skimmer is mounted very low, though - if you're skimming on the dry side during normal conditions, even if it goes crazy from pulling the floss it should be high enough to prevent a serious issue. One of the other big benefits of this type of skimmer is that it's so flexible - you can use anything you want for the collection container, put that container wherever you want, and the in tank footprint is so small that you'll barely notice it. You don't have to worry about your skimmer adding heat to the tank, and you don't have to listen to the crazy noises produced by a needle wheel pump. Once you use one of these you may just never go back (unless by some miracle a manufacturer decides to make a needle wheel skimmer for nanos that doesn't suck!).

    Makes sense! I sadly can't make a good suggestion because of my limited reefkeeping experience, other than saying that putting it anywhere in the back chamber will be efficient because of the turnover of water it will see. Putting the bottom opening of the skimmer in a moderate to high flow area helps efficiency greatly, since this type of skimmer doesn't have a directional cycle of water like most needle wheel skimmers do - sucking water in from one side, and outputting filtered water on the other. It instead relies on turbulent flow inside the skimmer body to cycle water, which does work surprisingly well, provided that the water near the bottom of the skimmer is cycled externally. One other thing I can add, though, is that they do tend to be great at manual gunk removal. The skimmer described above in the Bio Cube 29 gallon tank was in chamber 1, and it pulled out a ton of particulates and stuff (even bugs that fell in the tank O_o) before the water would get to the other back chambers. Whenever I'd take a magnet to the tank walls, all sorts of crud would appear in the foam of the skimmer and get ejected out the port. It's yet another reason the increased output spout size over the Mame skimmer was a real bonus. So I'd say your setup would depend on whether you want the skimmer to contribute to large particulate filtration first, or whether you'd like that task to be performed by the other stuff you plan on putting in the tank. Personally, I'd put the skimmer in first just since it *can* help with all that manual removal, and I'm lazy and this will increase the amount of time between changing the other media and cleaning the floss. But, like I said - limited reefkeeping experience - I'm not absolutely sure that putting the skimmer first is the 100% best way to go, and your situation may vary. There are other considerations such as if you are trying dendros in a back chamber, you'd want all that stuff they may or may not eat to pass over them before removal. It's just one part of the equation

    Yes to all counts. It comes with an airstone, the rings for the mount (if you choose that option), some spare rings (which are just cut from 1/4" silicone air line in case you ever need some more) and a small bit of airline connecting the airstone to the glass air tube. What you'll need to hook it up is an air pump of some variety (anything from the smallest sold locally such as a Tetra Whisper 20 on up), some 1/2" vinyl tube (I prefer black since it doesn't show skimmate buildup), and, if your air pump is not adjustable, I highly recommend a 1/4" Tee and needle or ball valve. To adjust air flow, you can hook the tee up to the valve before the skimmer, which will allow you to bleed off extra air. Putting on a couple feet of air line after the valve will make the setup entirely silent. Regarding the 12G Aquapod, I can't find a great picture of the hood setup, but it will certainly work for a 12 gallon size. The skimmer extends about 3-1/2 to 4-1/2 inches above water line, and the outlet of the skimmer must be above the level of the glass rim, so some modification may be necessary. Typical installation yields the outlet of the skimmer rising about an inch to an inch and a half over the rim of the tank. 32mm skimmers are approximately 1.5 inches by 2 inches in footprint, a total of 9 inches tall including the spout, and will work in as low as 6 inches of water. For a 28 gallon tank, you'll definitely want one of the larger models - probably the 44mm to give you the best flexibility for stocking your tank. The footprint of the 44mm is approximately 2 inches by 2.5 inches, and a total of 11 inches tall including the spout. It will stick out above water level by about 3-1/2 to 4-1/2 inches, and only having a couple inches between the wall and the tank will be just fine. I've seen one at work in a BioCube of similar size and setup - there was just enough room behind the tank (about 1.5 inches) to fit a flat 375ml whiskey bottle, which worked really well as a skimmate container. Sadly I can't give you advice about the hood, but hopefully having the footprint measurements will help. For the 44mm model, the Tetra Whisper 20 will run it fine, but the Whisper 40 is not out of the question for some extra power (with the above tee/valve setup) Hope this helps!

    Thanks for the reviews everyone! I really appreciate the kind words, and I'll do my best to keep providing great products and customer service - I think it's a great way to start a business, by building a foundation of quality and support. As always, if anyone needs some support on the various things I make, please shoot me an email or a private message here. I can't always keep up on the forums as well as I'd like, but I'll be sure to get back to you quickly in either of those mediums... It's distressing to see that one of these skimmers could lead to so much water loss - I'll have to experiment a bit and see if I can create an anti-siphon model. I'd also like to note, though, that the skimmer in the video is mounted a bit low for how much air is flowing through it. The dense foam column should end about an inch underneath the bottom of the dome, so I'd recommend a higher mounting position to prevent this. It does seem to be a special circumstance, since the floss was just pulled, but it would be best to adjust the skimmer during the increased foam if you don't have an anti-siphon installed as Tiki does. Finally, if you have any ideas for my products, something I should make or something I should alter, I'd sure love to hear 'em! Shoot me a mail - heck, I might even send a prototype out to you to test if you're willing to give me some feedback. You never know! Thanks for the support! -Calen
  5. Protein skimmer for 10 gallon reef tank

    It would seem someone else has been doing development at the same time as me... It looks like they even settled on black skimmate tube, probably for the same reasons (all clear tube turns a lovely shade of greenish brown - yum!) Begun, the nano skimmer wars have. As to the OP, air driven skimmers can be nice, even on small tanks. They're just enough filtration to keep parameters more stable between water changes, and they can be a real lifesaver if you somehow managed to anger a coral and make it slime by dipping it in revive at too high of concentration (DOH!). It may not be necessary for such a small tank, but it can certainly extend the time between your water changes, low in volume as they may be.
  6. Starting a 5.5 gallon nano reef

    I think we see the same site, but the price is not listed in usd.... check out the RB post on it: http://reefbuilders.com/2012/05/29/aqualighter-led/
  7. Starting a 5.5 gallon nano reef

    If you can find one, the Aqualighter Nano Marine is one sexy piece of kit. Roommate just brought one back from InterZoo and it's so tiny, with just the right balance of white/blue. Threw it on an 8 gallon Evolve and it looks like it was made for the thing. So far doing a google search though, I only see them in Russia. Perhaps you have a comrade who could send one *edit* After viewing the price, at about $50 it's a ridiculous value, even if you have to pay $20 to get it shipped. I'd grab one in a heartbeat.
  8. Setting up a Glazer skimmer

    With this kind of skimmer, the best placement of the airstone is going to be as low as possible without spilling bubbles into the tank - this will depend on the flow in the vicinity of the opening at the bottom, as well as how centered you can get the airstones in the tubes. For really great efficiency they can even be poking out the bottom of the tube, as long as the stream of bubbles is caught by it. As far as how far out of the water it should be, usually I advise people to start with about two inches of straight tube above waterline (my skimmers are dome style, so measurement would be to bottom of the dome, or, for Glazer skimmers, to the bottom of the angled cut), and then adjust to your particular style - raising the height above waterline will give you drier skimmate, lowering it will yield wetter skimmate. Adjusting the air flow will also impact wetness/dryness of skimmate - this is easily done by adding a tee to your air supply line and bleeding off extra pressure with a needle or ball valve. Adding a couple feet of airline after the valve will yield a completely quiet build. Welcome to the dark side
  9. Hydor Slim Skin Nano Noise

    Your skimmate shouldn't smell (much) when it's fresh - it should be like really concentrated tank water... if it's really really watery you'll probably end up dumping it all the time and it won't have time to break down. The most atrocious smelling skimmate comes from when you leave it in the collection cup for far too long and it's really broken down, especially if you've recently fed something that can produce nasty hydrogen sulfide gas (and boy will that make yer eyes water!)
  10. We have a winner!! If you put the return of the reactor under water, air won't be sucked in from the output of the reactor and the water won't really move. The GFO will still probably fall through the small holes (until you put a sponge or screen in there), but it shouldn't end up in the sump.
  11. Used Aquastyle 9

    For something a little more persuasive, you can try mixing equal parts vinegar and hydrogen peroxide (or slightly more H2O2 than vinegar) - the peroxide has a mild bleaching effect and the vinegar eats away at metals (as well as slightly softening the silicone). The two combined actually have an industrial name (sweet, delicious piranha solution - no way you should use that lightly, if you could manage to find the materials) when you use laboratory strength stuff instead of the supermarket variety, but the supermarket strength mix is still rather nice - you can use it to remove the surface lead from brass parts, clean copper tarnish easily and quickly, and do some other household cleaning chores without worrying too much about the lasting effects of chemical exposure since the peroxide degrades quickly and the vinegar is just... well... vinegar.
  12. HOB refugium ?'s

    If you decide to put an airstone in that to make it a decent skimmer, be sure to use a wooden stone, since regular stones make really huge, poor quality bubbles.... The solid ceramic microbubble stones are alright, but are a pain to clean and can wear out your pump quickly due to the increased backpressure.
  13. Ebay digital temp controllers

    The problem with super cheap temperature controllers is they also use super cheap memory, which can only be written so many times... if you never change your parameters it's often fine, but if you're changing things frequently, each time you change it, it gets a little closer to farting out and either becoming useless or not holding params when powered off. Fuji makes excellent quality temperature controllers, and you can often find them for decently cheap on Ebay... they'll require you to run a separate solid state relay to control your device(s), but it's worth it for the peace of mind and flexibility. Also keep in mind that your controller can only read temperature as accurately as the probe you buy - omega.com is definitely the place to find good probes. My NQXL has been above 1200 F and below -108 F and looks just like the day I got it (other than a slight change of color). Omega probes are great at minimizing the temperature drift associated with extreme temperatures.
  14. In the mean time, check out this video. If you're already running a HOB, the surface film shouldn't be too hard to get rid of.
  15. Gnome Glass Skimmers

    SHHHHHHHH!!!! Actually those are in development at the moment. I don't plan on ripping off the Mame design, because Mame's a great company, and if someone wants a Mame overflow, they should go to the trouble and grab one (I've seen 'em in person and they're definitely cool!!) But I am working on a continuous siphon nano overflow/surface skimmer of my own, which will be 100% glass and in all likelihood will have the same sort of mounting adjustment as the protein skimmers (the glass sliding mount) to adjust the water level of the tank. My rough estimate on international shipping is $12... that's a truly tiny tank, though. Please mail or PM me some measurements and I can make up something custom (perhaps adding it to the stock lineup in the future). Not to my knowledge... it would be neat if they were interested, though.
