This is almost exactly what I did last year. I however used an orbit walkway tunnel nozzle at the elbow to increase pressure with a valve you can use to control the pressure. I also put my CO2 reactor inline so that the water being pumped by my waterfall is completely diffused with CO2. My apex unit controls the solenoid attached to my CO2 tank and keeps my ph at a constant 7 - 7.5 ph. It's basically maintenance free. I only do top offs and a water change about every 3 months and my livestock of blue dream shrimp, plants, and various nano fish is thriving. I love seeing other people's methods of the venturi being used over the typical air stones. Great job on explaining this to everyone with the cad drawing too. Keep up the good work.
Followed this tutorial and have had great success. Very glad I used the powerhead and your method rather than the airstones. You are a legend. Thanks for your help
I have built the pipes, using a powerhead that was lying around and got the whole rock structure up and foam secured it but it was too heavy with all the rocks so I just dismantled everything and am going to follow your method. Thank you
I was into aquariums back in the 80's; I'm sure no one was doing such creative things back then. Though with no internet then it was hard to share such ideas.
This is totally awesome!!! Thank you for sharing this simple yet magnificent design. I now have part one of my plan to build my own waterfall. By far the best design. I love the graphics tutorial as well. Many thanks!
This happens to me too, the water pressure inside the second tube gets too high and returns to the first joint and gets out. It probably is because of the second tube being too high..... but i need the height in my aquarium. Any body that can help fixing this? I tried changing the angle i the first joint, but it didnt help.
Wow this seems like a great idea! I given up on sandfalls because the sand would get blown around too much and wouldn't where it needs to refill. I'd buy a pvc pipe setup with the slit you made if you are selling it?
Loved the video. Have purchased every thing you used. BUT how do I attach the power head motor to the 1 inch pvc pipe? the extension from the motor is very small. Please tell me so I can finish my sandfall
Hi Great video. Have been trying to build a sand waterfall but having problems. looking for advice thanks. Have built my T section the same as yours but it seems to be blowing back out where the sand should go in. Main difference between mine and yours. I have a round tank so have set the power head at the top behind the waterfall return at the water surface where most people and yourself have it very low or at the bottom in the tank. Thinking I may try a larger pump. have seen others with the same problem as me with no advice. Cheers Any advice much appreciated
I’m not sure what I’m doing wrong🤨🤨🤨🤨 I’m struggling with the cycle, stops at the T as if I didn’t put the plastic in, Bubbles out , however if I take the elbow out before it goes up the fall pipe the water flows and does not stop at the T😀It’s been a few days of working on this I’m usually pretty relentless but the fish need there tank back. Any suggestions would be so appreciated. Thank you for the best video
I am struggling struggling with the cycle working🤨🤨🤨🤨🤨 The water bubbles out as if I didn’t have the angle in the T😒 However when I take the elbow towards the fall off the water flows without stopping at the T. Putting the elbow and pipe back on the water stops at the T bubbling out. Any suggestions would be so appreciated. I am usually relentless but it’s been over a week and the fish need there tank back😉 Thank you for the best video excellent directions.
...Awesome. I have been wanting to incorporate a sandfall into the scape for a while now, I absolutely hate the hummmm of air pumps though. ....Venturi for the sand, ...freakin' ingenious, very nice. Hydrodynamics are slightly different from aerodynamics, ...or it may be all relative based on weight and viscosity?! ...Anyway, I do have a spare red sea pump from a CO2 system laying around and some plastic tubing so I will play around with it for a while. Thanks a lot man!
Thank you so so much. You save me i have a 158GPH powerhead. But i need to get a higher GPH for my 55 gal and i will do this.. About the sand are you using 1mm? Thanks
You're a genius! My question is how far away from the intake / output of a canister filter should this setup be? Or from any waterflow for that matter? Thanks!
Dear Keith, Thanks alot for the wonderful comment. As long as your powerhead can push out at least 350GPH you should be fine. But my advise is to keep the plumbing works as short as possible for a better sand flow. Or your sand might clog up with the natural sludge/algae created by running water over a period of time.
I'm in the process of trying to get my setup to suck in the sand but so far no luck. I have my T return laying on its side with a 3" tube (sand intake) under the waterfall outlet at the top of my mountain. I used 3/4" piping and the pump pushes 400 gph (the flow rate is adjustable). I've tried pushing the sand into the inlet pipe but there is no suction being created by the venturi. I have the venturi on a 45' angle and the plastic insert is past the 1/2 way mark in the diameter of the tube. Any thoughts as to why my sand is not being drawn in? Its aquarium sand no sandbox sand. Rich
Please help me. I am struggling with this project. I follow your instruction but sand flow out for 1 minute then the powerhead stop working because sand get inside the powerhead. I use 1 inch PVC and 400 GPH. powerhead. What am I doing wrong? Please HELP
Well explained mate , do u mind me asking what type of rocks you use and what type of sand you use, many thanks i look foward to your reply to these questions.
I did a similar build but I was having the water push up through the t-joint preventing the sand from falling. This is with the t-joint at a 45 and inserted plastic. Do you have any ideas? I did cut the top (collecting portion) a little shorter but wouldn’t think that would cause an issue.?.?
Ali Arif not sure...I ended up using a reducer within the t joint instead of cutting. With the right sand it works good. Amazon has a Venturi t-joint which works great too.
Hi Avideep. I didnt buy it. I made it. Check out my channel for the tutorials. ua-cam.com/video/IoQRn0_AJ3Y/v-deo.html&lc=z12qyb4a2yese5vdj233cfdinyqwitv2a
i already use a stronger power head and followed the instructions regarding the (slit)T joint but still the water escape from the T it's like the sand won't go down because of the water coming out form the T joint. what is wrong with it?
Problem 1: Something is blocking the outflow mouth of the whole setup Problem 2: The facing of the slit is in wrong direction (There is no way for the water to gush out if the slit if facing along the flow of water Problem 3: Powerhead (need at least 250 GPH) is not strong enough to push the force of water to the end of the setup up hence it will retreat and gush out to the nearest exit. Problem 4: The sand is not heavy enough to sink Problem 5: The Piping works must have too many corners (each corners will slow the flow of the water hence not enough force. These are all the problems which i can think off. Please update us if you have resolved the problem.
Hi Leo.. 1/2 Inch pipe might be too small and cause the sand to clog up somewhere.. or it could cause the sand to spew out all over the tank due to the water pressure. Tank size does not matter. If you want more complicated layout of your pipe, i suggest that you get a better powerhead.
@@ScooterFXRS so i build my own system, whole thing came out to be about 16 cm in height x 24cm in length, using 13mm pipes. I started with a 200l/hr pump and it failed, i scaled the pump up and experiment with the 3 pumps i had (200, 450, 600l/hr) and it finally worked with the 600l/hr pump
@@pbpyro5546 you are piped wrongly. The outlet which blows water is what you need to use. The inlet can be placeed inside a filter compartment not near the sand
@rakazaastudio2727 the piping goes ( 🌬➡️🕳⬆️⬅️ ).. lol best emoji description i have. So it's like a c shape. My issue is that the sand doesn't come out of the spout but out of the return hole that the sand comes from. This is why I think my pump isn't strong enough.
i did the same way with you but why my sand flow out from the T pipe? As it supposes to be the entrance of the sand. But the sand flowup immediately when i put it in. Could u teach me how to solve this prob? thanks a lot
Hi Yong quan. Did you check the direction of the T-pipe? Make sure the slit is facing away from the flow of the air pump. Also Make sure that the slit closes the t-pipe leaving a little gap for the water to flow through.
What GPH pump are you using? I suspect that the pump flow is not strong enough to push the sand forward thus the water is escaping through the nearest hole. Also what type of sand are you using? have you checked if your pipe has no blockage anywhere?
Hey mate do u think I need powerful powerhead as I have a very large tank holding 450 litres of water. Last time I gave this method a try every connection was perfect only problem I faced was the sand not coming out but I could feel the force of the water but not enough to make the sand come out.do u think the powerhead might be the issue?
No, more than likely you have not created enough suction at the venturi portion of the system or possibly the sand is clogging / the sand is too course[heavy] but these last two would be pretty obvious.
Ciao buona sera scusami ma non parlo inglese ho realizzato il tuo progetto ma dal foro di entrata della sbbia ho sempre una fuori uscita di acqua e non si chiama la sabbia potrei sapere dobe sbaglio graxie
Hola Amigo: el video esta espectacular... disculpas por escribirte en español. he intentado muchas veces su explicación y la arena se escapa por la T no he podido hacer que funcione. mi cabeza de poder es de 500GPH , la tuberia que tengo de de 1/2 , los recorridos son cortos pero el agua sale por encima de la T. por favor ayudame. mil gracia un abrazo!!!
Hi Rakazaa I tried this sand fall system but have one problem can you please help . So I did the T piece with the cut of 45 degree angle . But for some reason i have water coming out from the top of the T piece. So it push the sand out.

Hi, in my practice water gets escaped in first T-joint (t-elbo). It is not reaching second joint. What I should do?
This happens to me too, the water pressure inside the second tube gets too high and returns to the first joint and gets out. It probably is because of the second tube being too high..... but i need the height in my aquarium.
Any body that can help fixing this?
I tried changing the angle i the first joint, but it didnt help.
I have to say that this is the best explaination of this underwater waterfall on youtube. Thought the length and height seem to matter......
what a cool and simple idea
Wow this seems like a great idea! I given up on sandfalls because the sand would get blown around too much and wouldn't where it needs to refill. I'd buy a pvc pipe setup with the slit you made if you are selling it?

Hi, i have a question when you use waterfall set up.. is it okay not to have a filter in your tank?
so what sand pool filter sand?
thanks for sharing your idea..
Thank you so so much. You save me i have a 158GPH powerhead. But i need to get a higher GPH for my 55 gal and i will do this.. About the sand are you using 1mm?
Thanks
Yes. Its 1mm sand
Yes. 1mm or 1.5mm sand is fine as long as your powerhead does not spew them all over the tank.
Rakazaa Studio hello again i cant find a 1.5mm so hoping the 1mm will be okay. Ill update you soon
I made a waterfall with this design however the inlet is not pulling the sand in, it’s more so blowing it out some. What did I do wrong
Hi, great sandfall thank you for video why you prefered power head, instead waterpump?
Hi, I wanted to make the waterfall without having any bubbles disturbing my surface so that i can control my CO2 flow.
As I thought thank you for reply
In the diagram your power head is on the top but in your diagram it's on the bottom. Will a water pump at the bottom of the tank do this?
Hi mate, great video, what is the litre an hour rate of your powerhead? Thanks!
You're a genius! My question is how far away from the intake / output of a canister filter should this setup be? Or from any waterflow for that matter? Thanks!

How many watts of powerhead will used for fountain?
Black soil in the bottom. Is it entirely plant substrate or mixed with black sand ? Please reply sir
may i know what apps or software you use in drawing
