    I've an aquarium that is fertilized with CO2, so obviously I don't want to much oxygene pump in with a sandfall. I was wondering if it would be possible to bring the sand up with a waterbeam based on the venturi-principle.

      "cement" isn't some standardised material that always contains the same ingredients, there are aquarium safe cement just as there are kinds you should not put in your tank.

      +Gary Mcpherson well, that's really going to come down to how well it was made and how you mixed the cement/cured it. Sometimes they will start to crumble after a couple years if too thick of a layer was put on, on top of another. Several thin layers is best. If done right, they last many years. I have seen some that were 10+ years old.

    An air lift is a great cheap way to 'pump' that sand, but what about the horizontal flow? You are limited to a strict reduction in flow once the air vents behind the feature (which also causes noise and in my case a splashing issue).

    I have spent the good part of a week working on 'pumping' methods for sand that still are applicable to tanks you would find in a home.. I have a working model, cheap/easy to adapt/works consistently without anywhere near the constraints exhibited here.

    I would be interested in speaking in a more private forum regarding this project and others like it.

    To contribute something useful, it might be a good idea to install your "algae scrubber" behind the styro background. :)

    Hi Joey, this is Ryan from Mumbai, India I've watched a lot of your videos. You're amazing! keep up the awesome work man!..I have a question I'm building a sandfall and I wanted to know if the air bubbles created by the airstone (to lift up the sand) provide oxygen to the tank? I know it probably does but can I use use that as an aerator and remove my regular airstone oxygen? or not? If the answer is yes then I think my aquarium will look awesome with the sand waterfall doing the job of aerating the aquarium as well. thanks again!

      +I'mHungry great. I thought it would. thanks for replying back.

    • I'mHungry
      I'mHungry 10 months ago

      I think it will aerate your tank. By following the laws of physics of osmosis, the oxygenated water will flow into the unoxygenated part of the tank (from higher concentration to less concentrated area).

    Can you do a DIY hang on the back filter?

  • Omahaquatic
    Omahaquatic 2 years ago

    Joey, curious about buoyancy of the foam.  Have you had to hollow out the parts facing the back sides, or has the Quikrete been enough?  I've had a carving I've been working on for a similar corner waterfall, and I found the pressure of the foam wanting to float made me extremely worried about it popping up and out, yet as a waterfall piece I really look for not adhering it to the sides with silicone.  Really, I look for the best of both worlds, and if Quikrete is the way to accomplish that, no problem, but is it generally enough?

    • Omahaquatic
      Omahaquatic 2 years ago

      +The king of DIY Thanks much.  I'll have to consider it if my rock tower doesn't work out. Excellent work, Joey.

    • The king of DIY
      The king of DIY 2 years ago

      The cement will not hold it down, the silicone does. Use lots where ever it makes contact and give it extra time to cure. Generally up to a week. 

  • richard knight
    richard knight 2 years ago

    Hi again joey, ok so i tried a u in the pipe work and turned the flow right down but im still getting bubbles in my tank so im gona try and shorten the outlet pipe from above sump and gently lower to the tank via a series if bends and see if that helps, if not im getting a t piece and splitting the flow to try and slow the flow down not that its moving that fast i think its just the height of the sump tank above the display tank thats making the water turbulent.
    If you get a chance i put a video on my channel that shows what im on about
    Cheers rich .

  • Waseem Muhammed Ilyas

    Great video, i tried making sandfall twice, but had problems directing the sand vertically down .This video has made me wanna try it again. Also If you can make a video on natural looking, painted 3d background like ones made by " design by nature" it would be awesome.

  • b.a. Warman
    b.a. Warman 2 years ago

    It's such a simple principle but with an awsomely creative result.
    I might have to buy a new aquarium just to try making a background with na underwater waterfall.
    A few months ago i bought a Marina Dragon aquarium for my kid. I am now thinking that red sand and a red led light would be the perfect addition to it as they would create the effect of a lava flow.

      +The king of DIY That's what led me to find your channel, I was looking up freshwater rays and your vid came up! My husband and I want to get either a Scobina or Pearl ray and name it Chauncey. <3 We'd love to be able to dedicate a whole room to a shallow but broad tank, maybe 6 feet by 3 feet square, but we also have a pet duck, so we'd have a hell of a time keeping it out of the water and that just seems like a recipe for disaster...

    • The king of DIY
      The king of DIY 2 years ago

      +Amelia Bee ha! I was actually just looking at this old glass i had. It would make a 20"X5"X5" tank... I thought it could make for a really cute 2 gallon tank. Maybe make a miniature aquascape. Knowing me though... i would keep it bare and try to put stingrays in it. haha

    • Amelia Bee
      Amelia Bee 2 years ago

      +The king of DIY That's a relief! I've already got, like, ten of your vids bookmarked for when we move into a bigger home and I can finally pick up this hobby full-time, hehe! Although I do admit the miniature tanks have their own charm. It's like fish bonsai. And it's fun to find teeny versions of popular aquatic plants!

    • The king of DIY
      The king of DIY 2 years ago

      +Amelia Bee Totally agree. As i built this for such a small tank... i kept worrying about how i could make it look good. Definitely need to be in a tank 3 feet or longer. Although, with some creativity im sure people can make it work and look good. 

      For cleaning.. I wouldnt worry too much. The ore algae the grows on the rock, the better it looks. I never touch mine when i have them. For the pump, the sand will rub on the inside, but i cant really see enough algae building up in the back to cause any real issues... thats if the light even gets back there. 

    • Amelia Bee
      Amelia Bee 2 years ago

      +The king of DIY Sadly I don't have the money or space to dedicate to a tank large enough to make it worthwhile, I live in a townhome so my current obsession is with mini planted tanks. I've got one with crystal shrimp and another with pea puffers! 

      I do have one question, although it's in motion is there ever an issue with algae? It'd probably be a nightmare to clean off that craggy rock or inside the air pump!

    • The king of DIY
      The king of DIY 2 years ago

      Well, not really. I bred some for a short while about 8 years ago or so. I just tossed a few in a 30 gal tank with java moss and a sponge filter i made. (and a heater) 
      A few months later i had hundreds. Fed them algae wafers. Just dropped one or two in the tank and let them munch away. The java moss was probably the key to my success though. I ended up losing interest.... Was a super cool project at the time though.

      If the sand is rinsed and clean, it cant cloud the water. Over time, it would just get more clear. Not sure what ones you have seen, but i have not seen a cloudy tank with one done right. I didnt try ever sand size, i tried pool filter sand and something fine like playsand. Pool sand worked best.

    Hey joey, great videos.I have a planted tank above my display tank. As well as the bottom tank ,the water goes from bottom sump to top sump and into display tank and back to bottom sump the problem is the flow is strong, on sump pump turned right down it trickles not enough flow anyway the problem is micro bubble in display tank have you any thoughts as to stop the bubbles?. Thanks rich.

    • The king of DIY
      The king of DIY 2 years ago

      Turbulence in the return causes it. Make a loop (shape of a u) in the drain that causes it. Might have to use hose if you hard plumbed. The loop will cause the bubbles to rise back up instead of into the tank.

      No. Once you rinse and clean the sand, there is nothing to cloud the aquarium.

      To an extent yes, but i wouldn't depend on it. It would offer some biological filtration, however not by much. After measuring how much sand is actually moving through, i came the conclusion that it simply isnt enough. With that said, as it matures im certain it will compliment your main filter. This is as is though, im sure you could come up with a creative way to make it your main filter. The key will be how much sand you move.
