    That much new K1 would probably cost you more than you have just paid for that filter and all that media. If you don't use the filter stick it back on eBay and you could probably sell it for what you have just paid for it. Result

    Hi Johnathan
    Ill try get pics tomorrow. I didn't start until mid pm and it was dark when I finished and the light in the room is shit. The lights will be better when I set up the aquaponics grow beds. LOl. Only joking, i think! All that fish poo going to waste.
    Steve.

    Steve. Just looked at your plan. On the barrels. Looks good.
    Are you adding valves at bottom of each barrel to get rid of the waste.
    Or have i missed them. If not how are you cleaning them out.
    You sound as though your well into the game mate.
    Keep photos coming.

    So you don't see any problem with pump feeding the immersion tank and then gravity feeding the two barrels Fred?

    I suppose as long as the pipe from the immersion tank to the first barrel and from the first barrel to the second barrel are big enough to keep up with the fed from the pump then it will be OK?

    Just thought that you would need something like 3" outlets to flow via gravity to keep up with pumped supply without making too much back pressure in the system?

    Like most pump fed systems they are just a gravity system running backwards if that makes sense?

    Wasn't sure if it would be possible to fit 3" onto the immersion tank that was what was throwing me.

    I have pumps after all my filteration systems. and that is the only way I know. gravity in and sucked out with pumps. so to be honest I don t know about pump fed. but what I was getting at. is that all my filters have a discharge on the bottom of each filter to dump waste frim. after cleaning. like on an easy pod for example. you shut valve boil it with air and all the muck goes down the drain.
    on steves drawing plan I could nt see valves on the bottom to discharge the crap out. unless I have missed them. so I was wondering how he was going to clean them.

    when I had my old pond which was pump fed to easy pods x2 the pipe work was larger on the returns to the pond then the feed in from the pumps. so I reckon they should be larger then in.

    Yes I agree with you Fred and I couldn't see any option to flush the immersion or barrels either as I was more concerned about the system not working and maybe just overflowing if the outlets weren't big enough, like as you say they are on an Eazy Pod etc.

    I have only had pumped systems as I installed my ponds before finding this site so didn't know about bottom drains and gravity systems but what I found with the first system on my current pond was that with the box filter which was being fed via a canister type filter via a pump in the pond was even with the supply to it already being diverted before it got to it I still had to be careful how much water was being pumped through the 32mm pipe into it as even with the outlet of the filter being at least 50mm it was still very easy to get the filter to overflow as you can push more water into and through a pipe feeding a non sealed or non pressurised filter than gravity can flow it out through a bigger pipe. I think for it to work going by my box filter and an Eazy Pod experiences you need the outlet pipe to be about twice the diameter of the inlet pipe diameter. An Eazy Pod has 1.5" inlet and 3" outlet for a pumped system doesn't it?

    Hi Frim, all good points.
    here is a pic of the back of the tanks.
    I will run it without media first to see if it works, if the overflow allows pumped water to pass I will have to rethink that.
    Yes there are drains. Standpipes to tanks 2 and 3 so I can boil the media with a shop vacuum I have from the top of the standpipes> I dont think I need to boil tank one as that has no media, its just a vortex.
    And re the 3kw heater. That's the reason tank one needs sealing up and filling to top and to be vented. And I already have a 3kw on my IBC that is controlled independently with digital controller and stat in the fish tank.
    And my drawing should show 2 x 50mm gravity outlets from tank 2 to 3 and from 3 to the grow tank. new tank drain plan.jpg

    Nice description Steve, thanks.

    If I understand you correctly, going by what you have just said you may only need to seal the immersion tank as that is being pump fed. With the 2 barrels both having 2 x 50 mm inlets and outlets they may gravity flow from one to the other and out to the tank OK.

    New grow tank started at last.

    Form my original plan you will see I was going to drop the supply pipes to the bottom of tanks 2 and 3 and run a circuit of drilled pipe to allow water out but keep media from entering. But today I found some scraps of pig board. Its stuff I bought about 20 years ago to make pig pens out of. Its 1/2 thick recycled sheet plastic, really rigid stuff, had to be to be pig proof and pressure washable. Anyway, the barrels have these lovely rolled strengthening bands ideal to hold a slatted media floor. So rather than dropping supply pipe to the bottom I will create sumps and just bring supplies via a tank connectors below holed floor.
    So I cut some ply as templates and got them fitted ok, and then cut the pig board to shape and drilled loads of 9.5mm holes, just small enough to hold back the micro media.
    Looks like another cad drawing is required to show the amendments. lol.

    Hi Freddyboy. I know what you mean about gravity system, it was my first choice. One reason I like gravity is to do with the solids, as they pass though a pump impeller they are bound to get broken down a bit, so wont settle in a vortex as well as if gravity fed, and being liquidized cause more work on the other filter media. But I am doing this with materials to hand and a larger pump is not happening and I doubt my 3000Lp/h thing wont move the water around fast enough to shift tho solids off the tank floor anyway. And I don't really need a larger pump for my tank. Also, if I went off gravity because of water levels in the filters, my barrels are just too tall, and my No1 vertex/heater barrel, needs to be fully filled for the heater to function.
    Steve.

    New grow tank started at last.

    Here is a photo of work so far. Its been more planning than actual work, but as a carpenter/joiner/cabinet maker I am all into planning and drawing.
    I have taken on board your comments and suggestions. My pipework drawing shows 42mm dia, but that is only because I do not have a cad bolt on extension with 50mm pipe option to draw.

    Regarding flow backing up, I was always having twice or more the outlet size than the pumped inlet pipe size, so it does not back up and fill the filters, but I have changed the pipe routes and I now can have sumps in each barrel, and also done away with the overflows for now to see how it goes.

    Also the pumped inlet has been altered, as I think it was Frim who mentioned water taking its easiest route, I it worried me that water would fight to push up the vent pipe as it came out of the top of barrel 1, so I now have a 90 elbow immediately as it exits the top and has to go horizontal, and fitted a T in the horizontal pipe with a up-stand to the vert.

    Originally my fill pipe from pump to the vortex was all set at or below my fish tank water level, and I thought if I turned the pump off or it stopped, this 1st barrel would siphon back through fill pipe via the pump back into the fish tank. No bid deal, but if the heater was on it would burn out. Thus an anti siphon vent up-stand.

    I also have shown how I intend to install the media. In barrel 2, I will just fill it with knotted bailing twin sitting on a plastic grill, over a sump. Being a multi strand material it has fantastic surface area, AND I get tonnes of it.

    Barrel three will be divided into 3 sections, a bottom sump, then a grid with Alfagrog on top, another grid tray above the grog with K1 micro bubbling in air lines in the upper third. There will be screens to stop K1 leaving the tank.

    Still happy to take on board comments so I can fine tune it, its not built just yet.
    Steve

    Looking good Steve.

    How are you going to be controlling the temperature the immersion tank will heat to again?

    I only ask as you are using a 3 kW immersion heater element and if you have a separate stat it needs to be capable of running 3 kW which is between 12 to 13 amps depending on your supply voltage. A lot of the controllers I've seen only seem to be rated at 10 amps unless you can run the element via a relay that can handle 13 amps or more and then just use the controller to switch the relay via its coil.

    Was it you that asked this via another thread recently?

    I've been to sleep a few times since seeing that thread lol

    No not me, but I looked into it when I set up my IBC with the same type of 3Kw domestic heater.
    My stepson had a controller he wasn't using.
    I put details of it up on my very first post when i was starting the IBC., hope the link works.

    https://www.koiforum.uk/attachment.p...4&d=1541874305

    I manually set the immersion heater stat control to between 25 and 30, you cannot do much more than that with the stat control in those heaters, but I do it just in case the digital stat failed then I know the water heater wont go over about 25.

    I think as I have not seen a stat for an immersion heater recently that they have a thermal cut out fitted to them but as this is set to work at something in the region of 80 degrees C it won't be any help to you as you would have boiled to death anything in the tank at the time. Didn't realise the stats in them went as low as 25 degrees C but that's a hell of a lot better than 80 degrees C.

    If you need any help with drawing up a control system for the heater, controller and relay etc let me know OK.
