    I like checking out these old videos and seeing just how far Joey has come in his production quality and presentation skills. It's like night and day. Dude has made a ton of progress in every aspect. That's why he's the king.

      Love this, one question, If i make an underwater waterfall, will it give off air like a normal pump does? I only have 1 air pump and my fish need those bubbles lol, so does this waterfall give off any air into the water?

      Of course. It is underwater so O2 will diffuse into the water like any other source of air underwater... And yes, of course you will have a constant stream of bubbles emerging on top of your submerged waterfall.

    I used to use this exact system in 1970 but placed underneath a sheet of plastic which formed a bottom with a 1" gap underneath. This naturally used the sand/gravel as a filter bed. But I realise ideas have changed over time. Love your videos although I don't breed Discus anymore.

    Oh my goodness! I'm so glad I stumbled upon this video. I've been looking at all of the solutions to move water from a fish tank into a sump tank. So far, the options are pretty limited. 1: Extra pump, 2: Aqua bridge (of a sort), 3: Drill hole in side of tank. None of these solutions particularly excite me and each has it's drawbacks. But seeing as how you essentially made a PVC air lift and it has decent water flow... THIS is the solution; I'm sure of it. Liked + Subbed

    Awesome! I can see this technique used in a sculptural way. I can see wall sized versions that are 5 in thick with an unlimited way of creating backgrounds. My initial idea: Grand canyon walls with multi waterfalls complete with brush. Focused lighting would be a challenge. One question: how to get say 8 or ten waterfalls working together with one pump? Also, I wonder if you can disperse the sand evenly to create the effect of snow.

    Joey, I think you should do an update to this with the following modification. Seperate one corner of the tank as you would a weir using glass or acrylic. Place the spout facing the glass and use the same grain of sand. The partition will trap the sand at the bottom create an interesting background effect. I'd love to take this on myself and post it, but I lack the time! You're the man- give it a shot and show us what it's like!

    This is sooo cool! I was hoping for just a little more though. Like, would you build a styrofoam "rock" (like the one that covers the pvc pipe) with a stair effect for the sand to flow down? I'd love to see how that concept would work, instead of having the sand just fall straight down. Or do you think that may make a huge mess?

    Hi Joey, first off i'd like to say thank you for all your videos. It's been a great help especially since I recently moved to Colombia and its a lot harder to come across a good aquarium items here. I'm currently building a sandfall using your pvc method, using Styrofoam to build my mountain that will in return support the pvc. This will be my 2nd attempt since the spray paint melted the stryofoam I used . Needless to say my 2nd one is coming out a lot nicer. What can I use to paint that wont melt the foam? Will acrylic paint hurt my fish?

    Would be good for reef tank with internal overflows, of course minus all the sand. Use it in the same way but have it an inch or so above the sandbed. You could position it next to the overflow and it would help to bring fish waste and other debris to the top. From there it would be pulled right into the overflow. On the other hand i don't understand why you would want to cloud your aquarium with sand. Plus can't be pleasant for the pets we keep, breathing sand. Good vid, sparked lots of ideas.
