    I always wondered where your DIY name came from because when I started watching your channel you weren’t exactly doing diy crafts, just aquarium maintenance. I see what’s going on here! These are so cool. Why don’t you incorporate this into one of your new aquariums?

    hey Joey can you hide a heater behind the background as well or do you think it would heat the overall tank properly? i am asking because i want to the background for the sandfall and the the heater. the filter will be elsewhere. please let me know!

    What kind of air pump we use please tell me

  • John Leonard Fernandez

    but the sand behind the back isn't enough for 20 mins so we need to pour sand again and again and again and that could be the problem 😑

      The sand is suppose to keep falling into the front collection area. You could habe a plastic funnel in front as a collection area. My issue right now is trying to hide the bubbles somehow so they are visble.

    The king of King's! I really need your help. I'm a beginner to this but watched hrs apon hrs watching ur videos before I even began. All is great but the sandfall is really testing me! I used all of what you showed with rocks aiming the sand back to the bottom of the pipe but for some reason unknown I just can't get it to work I've tried fiddling with hight of pipe to sand and air stone to sand also pressure from the pump and nothing just tinny particals falling. Nothing like the videos you see where the sand is gushing down. If you help sort this problem you'll be my hero not just just the king lol :) thanks

    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.

    • Austin Salgat
      Austin Salgat 2 months ago

      With enough water changes all the tiny particulate are removed. Beforehand it's highly recommended to rinse your sand to get most of this out.

    • Strider
      Strider 3 months ago +1

      heavier sand. pool filter or river sand should drop straight down, but play sand for example, will come out like a mist and cloud the tank.

      "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.

  • Damn Yourugly
    Damn Yourugly Year ago

    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!

    • Ryan Murray

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

    • I'mHungry
      I'mHungry Year 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).

  • 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 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 .

    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.
