I'm one of the very-proud Malaysians to note that the had also referred to your idea to put the reducer on top of the standpipe as the first used or probably first written about in their "Japan Aquaponics DIY Aquaponics Guides: Autosiphons - Bell Siphons & Loop Siphons". I consider you as one of the aquaponics-Guru of Malaysia and this is an excellent blog for its well documented experiments and articles in aquaponics. Thank you again, for any advice you can provide. I'm expecting 4-6 cycles/hour.Īm I figuring things out in a reasonable way - or am I way off the mark? Which siphon size should I start with for the best chance of only needing minor adjustments (not having to drill a brand new hole - especially a smaller hole! ) ). In my grow bed, (taking into account the space media takes up) will be draining ~25 gallons (~100L) of water each cycle. My pump is adjustable, and I'm expecting ~125-200 GPH (~500-800LPH)with the head/pipe run I'm using, but won't know exactly until I start things up with pipe attached (I'll be reducing with 1/2", from 1" out at the pump, because the pump I picked up has room to grow if I add another bed higher up later). The fish tanks up-top are where I'm going to raise some crayfish and some cherry shrimp (well, I'll try) in addition to in the main fish tank, along with water lettuce or water hyacinth for filtration. The grow bed is 44x44x12 inside, will always have ~2" water at the bottom, and the ebb/flow zone will be 8". Here are a few images showing the setup I'm thinking about right now. I have a question of my own, as well - I hope that's OK :D People out there really respect your work and openness in sharing it! Thank you! I'll let you know how it went after I experiement on Saturday.Īs I get closer and closer to beginning construction of my kitchen-window setup, I'm nailing down details and every recommendation about siphons leads here in the end.
If there were another product or object that could be easily found to use I am open to suggestions. Ideally I would like the two separate systems to be a 1.5 inch drain and standpipe with a 3 inch to 1.5 inch reducer and a 5 inch bell, but alas, 5 inch PVC is not a standard size here in the US and I cannot find it. These to be constructed externally using a bucket as well (much cheaper than assembling the housingout of larger PVC fittings!). I will use 1 inch standpipe and drains with a 2 inch to 1 inch reducer and a 4 inch bell. I will use an 8 gallon plastic pail with appropriate plumbing as the external housing for the mega siphon (a bit taller than a standard 5 gallon).Ģ) If that doesn't work I will use two Mega-Siphons, one each for three IBC growbeds. I think then that I will try 2 things.ġ) a single Mega-Siphon for a ll 6 beds using a 2 inch drain with a 4 inch to 2 inch reducer. Never done a Mega Siphon before, a very tall ones I did but not Mega. Hope this work, this is great, please keep us update. You can reduce water flow, don't really need that high of a flow rate, but if you do then these are my recommendations. Tuning this siphon to work will be fiddling with this downward vertical and the stand pipe funnel. Handling that volume of water, you need a good initial vertical from the siphon outlet then an elbow one would do, if you could have 12" of initial vertical as a minimum, it would be great. I would recommend a 2 inch stand pipe with 3" to 2" reducer or bigger, but don't exceed 1:2 ratio, if cannot get reducer you can flare it top to make a trumpet like shape funnel it will work.īell size must be able to take the widest part of the stand pipe, I recommend for 3" you need at least a 5" PVC pipe. So working on that figure, my 25mm or 1" siphon stand pipe will work up to 1400 ~ 1600 lt/hr flow. Because this is the most important figure to take. These statements came on the heels of the resignation of Grover, in which he claimed being “forced to bid adieu to a company of which he is a founder.” On the other hand, BharatPe’s statement which came on March 2, said that as a result of his misdeeds, Grover is no longer “an employee, a founder, or a director of the company.” The company did not comment on whether the board decided to accept Grover’s resignation or terminated him.Affnan 19 April 2011 at you only need to take into account the 3600lt/hr rate to design a siphon. The only thing lavish about me is my dreams and ability to achieve them against all odds through hard work and enterprise,” he added. I would also want to learn who among Amarchand, PWC and A&M has started doing audits on ‘lavishness’ of one’s lifestyle. “It (the company’s statement) comes from a position of personal hatred and low thinking. In response, Grover said that he is appalled at the personal nature of the company statements but not surprised. Ashneer Grover proposed Madhuri Jain’s resignation in a Jan 19 board meeting
