Methane harvesting from waste gases of aquaponics sump tanks?

Does anyone have any knowledge of this? I can't find much by researching on the Internet

Edit: similar to this

This was yesterday's harvest to grab your attention. The problem is that it's the first harvest in almost two weeks from my media bed, when it should be every few days. I recently lost my nearly mature tilapia and have a question (see comments).

What plants can help change the water in aquaculture tanks?

Okay so my highschool agriculture department has aquaculture tanks. My teacher wants me to do some research about what plants we could use to help regulate the ph and the water hardness. I spent an hour googling stuff I thought would help but I can only find plants that can live in low ph and hard water.

So I thought you guys might be able to help?

Any Ideas?

Help needed with 1 project

Hello aquaponicists,

first post here and first indoor project. I recently bought a 30L aquarium and would now like to put it into operation.

I have come up with a plan and would like some feedback.

The water runs from the aquarium into 2 individual pots (one with mint, the other with chives) and from there into a larger bed, in which 3 herbs are to be placed. I wanted to plant basil, a head of lettuce and an xx (I don't know the last one yet...) in the larger bed.

I want to grow 2 smaller aquatic plants in the aquarium itself and hang an ivy plant in the aquarium.

The aquarium should contain 15 danios (e.g. https://en.wikipedia.org/wiki/Boraras_brigittae), 10 shrimps (e.g. 10 dwarf shrimps) and 3 snails.

  1. is such a setup even possible in terms of the fish/plant ratio?

I'm afraid there are too many plants and too few fish...

  1. should I replace the lettuce? If so, with what?

(This is just the best I could come up with anyway)

Many thanks in advance :)

Texas tilapia

I’m confused, some sources say a permit is required for any tilapia except Mozambique. Others say Nile can be stocked in private water. Are there any Texans that can chime in and let me know if I can use Nile tilapia? Thanks y’all.

Filtration for drip watering

I have a system that pumps through 10gph drip emitters to towers and buckets. Problem is, whenever I shut down and restart (or do anything that disturbs the system), some of my emitters inevitably get clogged. Some right away, some hours later. Otherwise, mo problems as I have two separate gravity wells for solids.

What do you use for in-line filtering?

Do you know of an in-line raft type filter?

Would a large filter housing with a 25 micron filter cause issues?

Maybe a large t-body type filter?

All the things! Radishes, strawberries, chocolate mint, cilantro, garlic, maybe a carrot too. And the fig tree is putting on new buds.

Better to start with a young plant, or mature?

I’ve been trying to google it all day but haven’t really found a definitive answer. I have multiple fish tanks that I’ve successfully grown pothos from. I received my Etsy order of a bunch of philodendrons but I’m trying to find out if it’s better to start the plant out in aquaponics or let it mature a little while longer in soil for better chances of transitioning?

Sorry if this is easily found in a guide on this subreddit, I almost posted to the planted aquariums subreddit and thought to try here first.

Aquaponics in an off-grid low-maintenance situation?

I recently saw a video on Youtube about aquaponics which got me thinking that it could make self-sufficiency easier, then I saw a video where a guy had an aquaponic system off-grid and said it required too much maintenance. I love the idea of the symbiotic relationship where the fish helps the plants grow and I can get 90% of my food straight from there.

Tilapia seems to be the fastest growing fish that works well in this system however most nights where I live get to below 60f which is the temp they seem to die at. Not to mention the pumps and filters and general upkeep of these systems don't seem to fit in an off-grid system for a guy who works full-time.

I guess my questions are:

  1. would a greenhouse work to keep the heat in so the fish don't die or would adding a water heater be the better choice?
  2. I know how to make a homemade water filter but would those even work for a system like this?
  3. is evaporation a big issue for you guys or am I trying to work my brain too hard?
  4. How long do your pumps last?
  5. Would it be smarter to use one big tank or a few smaller ones?
  6. how big of a tank / how many tanks would you say it was take to be well fed while keeping maintenance to a minimal?
  7. how many hours a day/week would you say you have to put into maintaining your system?
  8. how much money goes into it?

Overall, it seems like a great idea, being able to grow protein and greens together with little waste but is it too good to be true? I need this to be an off-grid system or at least be able to transfer it into an off-grid system and with that I've been seeing it seems very difficult to make that happen.

Edit: I figure if this ends up working out, I can use a small solar panel to charge the pump and keep it running and subsidize my diet with eggs, fruit, and goat milk along with the veggies and fish. Along with rain water collection and a wood gasifier I'd be set for life granted I purchase enough replacement parts.

Also wondering if earthworms and duckweed would be enough to keep the tilapia well fed or if there were any other plants I should grow alongside the system to give them a healthy diet?

Couple beginner questions

As a kid I used to have a few live terrariums which thrived, but now as an adult I'm looking into aquaponics which I'd like to construct in my garage.

I have a 320 gallon tank that I'm looking to use as a fish tank. I'd have live plants, snails, shrimp, plecos, and tilapia in the tank. I plan to provide good cover on the bottom of the tank as shelter for these others from the tilapia. The grow bed would be 32sq ft to account for the 320 gallons. I'd likely only have about 5-10 tilapia in the tank.

My questions are...

Is a solids catching tank necessary if I have snails, shrimp, plecos and live plants to clean up the excess solid waste in the fish tank?

How bad will the smell be, in general? My garage stays closed most of the time.

I don't plan on eating the fish unless in some emergency situation. Will they breed in the tank and overpopulate? To avoid, should I get all male or all female tilapia?

Thanks in advance!

Can redclaws live in muddy water?

Ive seen videos of folks farming redclaw crayfish using grow out mud ponds (and I don't even see any air systems) and they seem to harvest quite well.

On the other hand, all the RAS systems talk about keeping the PPC below 50.

Id imagine in the muddy clay pond the PPC is above 50. So what's the ideal condition? Cause it does look like they grow up to big sizes in the clay pond than they do in clean water systems.

Anyone who keeps red claws can comment please?

Media specifications datasheet: MBBR, K1 Media

Hi everyone,

I am working on a small project to design an MBBR and I was wondering if anyone would have a detailed product datasheet of the K1 media and could share it?

I have tried all websites possible to find a datasheet that would list the total surface area and total volume of the media (not protected surface area) but so far I find varying information ranging from 800 - 1200 m2/m3 for the media and I wanted to cross verify my information. I would also like to know their porosity/void fraction but this data is barely available in all datasheets I find online.

I have also tried to contact various suppliers but their datasheets always mention only the protected surface area but I would like to know the total surface area for my knowledge. I have also contacted AnoxKaldnes but they did not reply to my emails.

If anyone has this datasheet please do share it and I would be super grateful!

Poop settling in corner of IBC?

Is there any creative way to prevent poop from accumulating in corners of my IBC? I have a SLO in the middle, and a settlement tank that works great. Every day I get a ton of poop trapped in the corners.

RGB Garage light as grow light

Hey all!

I've been using the 5000k 4000 lumen basic version of this RGB Smart Garage Light as a grow light for my kratky tomato setup. It's been working really well so far (no tomatoes yet, but they went from seed to 2 feet tall in like a month and a half), but it's been a hassle having to manually turn it on and off at the start/end of the day. This might be a dumb question, but the RGB Version shows the same lumen count, so arguably would it be better for growing since I could tune the light to specific temperatures? Plus I could schedule it to turn on and off.

What are your thoughts? Ofc a grow-specific light would be ideal, but 25$ for a low-power and low-stress option feels pretty great to me.

Thanks in advance!
