Poop, its poop water

Very awesome! That’s my ultimate goal to run my systems off of solar!

Thanks

Thanks

Yes but a very slow rate so that the moisture content of the wicking bed is at an optimal percent. Too much water and the water will not drain fast enough creating a water logged soil which would kill the plants. I can almost let the water run at it's slow rate for a few days until the optimum moisture content is reached and then turn off the water and let the plants dry out the soil and then turn the water back on to repeat that cycle. I don't do that because I have it hooked up to my aquaponics system so I let the wicking bed filter my aquaponics water.

It's 20 ft down horizontally. My aquaponics setup here is an inline setup. The top of the setup is the wicking bed, then the dual root zone flood and drain grow bed, then the sump, then the fish tank, and then the radial flow settling tank. The water elevation difference in the whole setup is roughly 4 feet with the greatest water elevation difference being between the sump water level and the fish tank water level. Someday I'll make a hydraulic gradient line video for this system.

Been using this sand/soil grow bed for three summers now (2022 to 2024).

I can use a GoPro to film them. :)

@robguyatt9602. Water properties are opposite, the solids will accumulate at the center, do an example on your own by stirring a bucket of water with some sand in it, stir with a spoon.

@robguyatt9602 - for mineralization of fish waste water or in making compost tea from worm casting there are two methods. 1) the classic bucket or trash can/bin aeration where you place air stones at the bottom of the bucket or bin. Here the air stones provide the oxygen (BOD) for the microbes to decompose the waste and keep the water aerated and moving. 2) using a vortex aeration the vortex takes place of the air stones providing the oxygen (BOD) for the microbes to decompose the waste and keep the water aerated. The physics of the vortex allows for natural aeration of the water to take place, hence one does not need air stones to aerate the water. A simple way to look at it is, as the water speeds up as it closer to the center of the vortex, more air is "pulled" into the vortex water column. With vortex aeration, you can either have a water pump create the vortex as it sucks water from the bottom of the bucket or bin and pumps it to the top of the bucket and because of the opening at the bottom of the bucket/bin a vortex is created. In this setup, one needs a sump for the pump to be placed in. The vortex bucket/bin drains into the sump and the pump pumps water from the sump into the vortex bucket/bin. In my case, I don't have a sump nor water pump but an air lift. The air lift lifts the water from the pipe at the bottom of the bucket/bin and then discharges it at the top of the bin thus creating a closed loop water cycle without the need of a water pump and sump. Less parts and pieces. As the air rises in the air lift pipe, it pulls the water with it. There are disadvantages to both systems but with the vortex aeration setup the farther the water is away from the center of the vortex the slower the water's velocity is. This is not advantageous because the water near the sides of the bin/bucket are not moving fast enough to have the particulates stay suspended in the water. So with this setup there will always be particulates at the bottom of your bin/bucket and if there is enough build up of particulates on the bottom, the mineralization process will turn anaerobic when you want it to be aerobic. This is why several times a day I open the drain valve and remove some of the particulates on the bottom. What I collect I put back into the system for further aerobic decomposition. Another disadvantage with vortex aeration with air lifts is that dissolved oxygen (DO) levels are not as high as the standard air stone aeration thus you are limited to the amount of mineralization or compost tea making your can achieve. A water pump and sump vortex aerator could possibly achieve higher DO levels but that would depend on the flow rate of the pump and size of the bucket/bin. To know for sure, one would need to measure the DO and calculate how much aerobic microbe decomposition one can achieve. When finished mineralizing or composting brewing, I open up the drain valve and fill my buckets with the water and let the particulates settle over 24 hours. Once the particulates settle, I have clear water to put back in my aquaponics. I then dewater the particulate sludge and add it to my homemade compost. The above answers your question but if you have more questions, please let me know. APOLOGIES for taking so long to reply!

@@sudeshramdhanie6216 Yes. That's why I have a drain to remove the particulates at the side of the bin. The drained particulate water is put back into the system. It would be better to have a conical bottom so I wouldn't have to do that but I wanted a cheap DIY setup.

@@sudeshramdhanie6216 Not so. The congregation in the center is only AFTER the particles have sunk to the bottom. The swirling of the waste laden water does cause the denser than water particles to go the the outside of the column of rotating water. This allows cleaner water to be extracted from the center of the tanks before the settling is complete. This is basic fluid dynamics which I studied as part of my Mechanical Engineering course. I subsequently worked as a designer of materials handling equipment which included dust separation cyclones for things like cement particle size separation and sawdust extraction systems for timber milling and wood working. The same principles apply whether the fluid is gas or liquid.

@@eskunkel Thanks very much for your detailed reply. So I was wondering how the vortex assisted settling when that's not the purpose but aeration is. Got it :) If you read my reply to @sudeshramdhanie6216, you'll understand my background and note especially that I have no experience in biological systems hence me thinking it was about filtration. Where I am right now and why I'm looking at Aquaponics is I'm keen to take it up as a hobby. I'm winding down my mechatronics business soon. My system will be based on my 1000L fish pond. It's been breeding Goldfish for decades but I got bored with them so being a Fly Fisherman I thought I'd give Rainbow Trout a go. Last September when we restocked my Son's farm dam I put a dozen or so fry in the pond and got rid of the Goldfish. At this time I have 3 Rainbows between 9 and 11" long. I am using a mechanical filter and pond pump in the pond. For the Nitrogen cycle I have several water plants in the pond and as Ammonia rises I just add an extra plant or 2. Currently Ammonia and Nitrites are trace amount. Before next September when we get the next batch of fry, I will build the grow beds and complete the system. Oh and I forgot an important factor between now and September. I will have a feed of home grown Rainbows. 😁

I’ve retrofitted my vortex aerator so I’ll upload a video about that upgrade.

Thanks so much!

Sorry, mate, for taking so long to reply to you! Been beyond busy. I'm in Central Texas so in the summer we can easily get 40C temps (105F) and in the winter for a brief couple days -10C temps (15F) or colder. I can't imagine doing aquaponics in Newfoundland! I've made everything in my 2 systems except for the pipes and pumps of course. I try and get the stuff for free at construction sites and buy as little as I need. I made 2 greenhouses for my two system also from scratch. I'll made videos on those. This winter my tank water go down to about 4C (39F). This affected the fish badly. I have koi, hybrid stripped bass, and largemouth bass. The koi did ok but the hybrid stripped bass didn't do to well and the largemouth's metabolism almost slowed down to not being alive. But over all things went well. My mosquito fish breeding tank froze again and killed most of the fish. But that tank is outdoors with no cover and only has a small 100 gallon fish tank heater. Next winter I'm making a solar water heater to see how that works out. Cheers, mate. I lived in Cardiff from 2013 to 2018. Loved it there.

The purpose of the breading tank is to bread the minnows to feed my hybrid stripped bass and largemouth bass in my two aquaponics systems. My stripped bass are 18" long minimum and I have 7 of them. I have 9 largemouths at 5". Bass only eat live food. :)

@@eskunkel Wow!! So interesting. Thank you for replying

Thanks! Will do wrt to the under water camera.

Thanks!

Thanks, mate.

Hello. I can try and make a video of this tank's construction but it would be after the fact. I constructed the tank from pallet pieces for the sides and 1/2" plywood for the bottom. Across the bottom transversely are 2x4s supporting the bottom plywood and providing support for the sides. The tank is lined with 50mil pond liner which is wrapped over the top of the tank and stapled on the top of the sides of the tank. Then I screwed a 1x4 finishing piece on top of the liner to make it look better. The effluent weir pipe penetrates through the bottom the tank where I installed bulkhead fitting. A uniseal would not work because of the 1/2" plywood. I used silicon to seal the bulkhead fitting to make sure it wouldn't leak. No problems with leaks. I also painted the tank to keep it from weathering. I raised the tank so I could put the filter below and more or less out of sight and so I wouldn't have to bend over to do any cleaning or feeding. I'm a structural engineer so I used that knowledge to design the tank. The legs of the tank are supported on concrete pavers. I should have put the legs on bigger pavers but didn't. The tank thankfully has settled more or less evenly. Thank God. If you use your plastic pond I would wrap it with an nsulation blanket and build a wood screen around it to protect it from the elements but you don't have to do that. RE wasps, etc, I just bought wasp killer to kill the nests underneath if they are even built. I had one instance of that in the 18 months since I constructed it.

Yes I can add a drain but it wouldn't drain the tank all the way due to the tank is partially burried.

Yes, friend. But the most beneficial and helpful plant of the three types of plants I have for breeding the minnows is the hornwort (Ceratophyllum). Its a minnow fry's perfect safe habit for growing and not getting eaten. :)

I took care of the SLO siphon problem by drilling a 1/2" hole in 90 bend. I clean it out if needed so there will never be a siphon with the SLO.

@@eskunkel that would work. Good one

Thank you! Cheers!

Glad you enjoyed it!

Thanks for the idea, mate.

i use a milwaukee stick pump hook up to a 100ft garden hose to water my garden while sucking up the waste

You could put a seine net weight it and place inside your solid waste filter and just simply pull it up trapping the heavy solids when you want to clean it out !

Thanks so much!

Thanks, my friend!

They're in the works!
