shadoh Posted March 13, 2012 Report Share Posted March 13, 2012 I saw a link to this on the IBC forum last night and thought it was a promising concept. IMO it would need to be larger to give the fish more room and accommodate a heater, but the concept is great and could be adapted for Barrack designs as well. The waste works it's way through the rocks to a reservoir underneath. To do a water change, pour the fresh water in and the waste gets flushed out... http://nocleanaquariums.com/85-2/ Link to comment Share on other sites More sharing options...
zhong89 Posted March 13, 2012 Report Share Posted March 13, 2012 Good concept, really makes me want to get one. but as a hyraulics engineer I'm wondeirng is there enough energy for the siphon to work properly Link to comment Share on other sites More sharing options...
shadoh Posted March 13, 2012 Author Report Share Posted March 13, 2012 Looks like there are other sizes in the works http://nocleanaquariums.com/85-2/about-us/ Link to comment Share on other sites More sharing options...
betta_splendors Posted March 13, 2012 Report Share Posted March 13, 2012 lol thats pretty cool. pretty simple concept and design :) Link to comment Share on other sites More sharing options...
kermadum Posted March 13, 2012 Report Share Posted March 13, 2012 Interesting idea indeed! It'd definitely be useful for jarring time. Link to comment Share on other sites More sharing options...
Pyrefly Posted March 13, 2012 Report Share Posted March 13, 2012 This is an interesting idea! Not sure how one would adapt it to a barracks setup though, I sense the water would have to go in one end and out the other to prevent backflow? Link to comment Share on other sites More sharing options...
shadoh Posted March 13, 2012 Author Report Share Posted March 13, 2012 You would just adjust the overhead flow so the container wouldn't overflow and the spout would empty into a gutter system... Link to comment Share on other sites More sharing options...

melbournebetta Posted April 17, 2012 Report Share Posted April 17, 2012 Well I have been thinking on this for a while now, and I'm trying to streamline my juvi grow out barracks, I've got containers all sitting in a bay-maree style with one heater and around 18 large containers sitting inside. Just for starters - totally hypothetical, and based on the principals of these no clean aquariums: http://nocleanaquariums.com/85-2/ Do you think this could potentially work, if I bought several beanie boxes, had them all flooding out into the bay-maree (which would then have a tap on it to drain and refill with clean water) Forget the logistics of what materials for a moment (that bit is next) would this work? I am not scientist. -MadinventorNess Link to comment Share on other sites More sharing options...
zhong89 Posted April 17, 2012 Report Share Posted April 17, 2012 u could try it with simply things such as a drinking straw and the beanie box. I'm not completely sure but I don't thing you could have enough head (energy) above the outlet to create a suckion effect to get the entire bottom of the beanie box. But then again the size of the pipe may can creat a big enough force to drag it out. Link to comment Share on other sites More sharing options...
somchai2500 Posted April 17, 2012 Report Share Posted April 17, 2012 Hey Ness. I am in the process of designing something similar. In a tank situation Suggest you try with various outlet diameters to create a suction/ drawing action. If you look at the video there is definitely a concave false bottom to the jar. also the pouring of the water into the jar is a little aggressive this could be to help start the drawing action. Hope to have mine up and running soon. Capillary Action demo Link to comment Share on other sites More sharing options...
shadoh Posted April 17, 2012 Author Report Share Posted April 17, 2012 From what I can see, where you have the mesh in your design, they have a funnel like reservoir. With the mesh, you'll just get all the waste washing back up into the main section when adding new water and just creating a mess. With the funnel design, if water is being forced down through the hole at the bottom, there is nowhere for the waste to go but up through the outlet tube... Does that make sense? Hope so, cause it made my brain hurt *lol* Link to comment Share on other sites More sharing options...
zhong89 Posted April 17, 2012 Report Share Posted April 17, 2012 it's not Capillary Action that drives this... it works by having a higher energy inside the tank than outside the tank. The reason that the water comes out is the tank trying to decrease that energy. A capillary action works by surface tension, the density of the liquid etc. Got nothing to do with self-cleaning tanks. If you want to research the siphon action is much closer to this design and will benefit you. Link to comment Share on other sites More sharing options...
Bettarazzi Posted April 17, 2012 Report Share Posted April 17, 2012 In your design Ness the outlet is too high. You need to drop it a bit so that when you fill with fresh water, there is enough pressure to push the water out. The siphon thingamajig that I brought along to the first VB meet we had last year works on the same principle. Link to comment Share on other sites More sharing options...
melbournebetta Posted April 17, 2012 Report Share Posted April 17, 2012 Razzi, I have to admit I thought of that siphon- and still don't have enough of an engineer's brain to understand it. Okay - Round 2! MAD PROFESSOR CHALLENGER, READY - 3, 2, 1 - FIGHT! WHAT IF I got a PLASTIC FUNNEL: .. Cut the large end so it has a SQUARE shape that fits in the beanie box... all the gunk goes STRAIGHT DOWN, I work a way to obscure the hole so Mister Betta won't get stuck.... Yes? no?

zhong89 Posted April 17, 2012 Report Share Posted April 17, 2012 that might work Link to comment Share on other sites More sharing options...
melbournebetta Posted April 17, 2012 Report Share Posted April 17, 2012 THATS AS GOOD AS APPROVED, BABY! so a thinner tube would also be better for the sucking action yes? I'm thinking bigger than a straw - not as thick as those external filter tubes.... Link to comment Share on other sites More sharing options...
zhong89 Posted April 17, 2012 Report Share Posted April 17, 2012 if you use funnel method u wouldn't need suction... I guess use a size that will high enough velocity to carry the waste but not let itg stuck in the middle. Link to comment Share on other sites More sharing options...
melbournebetta Posted April 17, 2012 Report Share Posted April 17, 2012 hmm - not sure what you mean by not needing suction? I'm still filling the beanie box with water from the top - hoping force would send all the dirty water out - same as the stupid invention that got me started on this in the first place. We still on the same page? Link to comment Share on other sites More sharing options...
Bettarazzi Posted April 17, 2012 Report Share Posted April 17, 2012 You could probably just shape the funnel into a square if you put it in boiling water then jam it into the beanie box. But isnt this getting a bit expensive? Beanie box $4, funnel $2? Tubing? Outlet tube like a sprinkler system elbow $1? Link to comment Share on other sites More sharing options...
