There is enough I don't know about your system that I can't answer those questions. I might not be able to answer some of them even if I did know everything I needed to but I'll try to get you started where you can find what you need.

For the aeration in the biofilter to get the media boiling (it should look like a light boil unless you're trying to clean the media) - This is going to vary with the amount of media, type of media and shape of your container - Here are some pump recommendations based on media volume (the numbers in the pump name are the max LPM the pump delivers (at least in this case)) - http://www.evolutionaqua.com/acatalog/K1_Filter_Media.html. I think their estimates of the pump needed might be too high but can't be certain.

Take a look at this and see if it answers your questions on aeration in the DWC troughs - http://teca.fao.org/read/8397

Tilapia are very durable fish and can tolerate very low dissolved oxygen levels. On the other hand, they'll grow better with good conditions so if you're planning on lots of fish then you need to aerate (keep the DIO above 5 and preferably higher). If your stocking rates are low just water movement may be enough. Given what you've told me I would aerate the fish tank especially if you see the fish hanging out up at the top of the tank like they need air. If you want to figure this more accurately then this article by Dr Rakocy should help - https://thefishsite.com/articles/tank-culture-of-tilapia.

Hope this helps :thumbright:
Thanks for the reply !
I would again like to mention that we won't be using telapia due to the on-going dispute politically about it being banned.
We will be using Catla Carp instead.

Also, the link states we need to use around 4 LPM in 2-4 m2. The hypothetical aeration is then just an overkill. I would make the changes and post how it goes when system runs ^^

The pumping of water is practically 3000 LPH. We have calculated it so it should be good !

Oops, forgot about the fish switch. I think the DO requirements for Catla Carp will be similar to Tilapia. Their transport requirements from this abstract (https://www.researchgate.net/publication/267559592_Oxygen_consumption_of_carps_during_live_transportation) look like they are in the middle of the Tilapia range from the Rakocy paper and carp are usually pretty good at survival in low oxygen water.

Oh yes ! Good to read the paper and nice comparison of the local fishes. Actually Catla is a "canal fish", they breed and live in almost any water body. They are strong and people love eating them in India.
I think transportation should not be a problem as the max time it's gonna take for transportation is 1 hour. Do you recommend salt bath for new fishes before being put into system ?

Probably a good idea. A lot of people will quarantine the fish in a separate tank so that they don't introduce diseases into their main system.

Thanks ! And we are growing indoors. We wanted some help with the light setups. We are going to use LEDs and guidelines say it should be 30-40 watts per square foot. And temperature should be 6500°K. Anymore points or a handy guide we could use to set it up ?

6500°K - 7000°K is daylight and being old school that is what I would have used, with a little bit of heat output, but now they use COB LED, with red light added to the daylight.

COB (Chips on Board) , is a new technology of LED packaging for LED light engine. Multi LED chips are packaged together as one lighting module. When it light up, it looks like a lighting panel..

The diagrams are a guide to output and height.

Thanks for the reply.
Grow lights of any kind are very hard to find where I live. The online stores provide them with no guarantee or warranty. The local stores only have traditional CFL, halides etc. But I'll search for more.
The diagrams were super helpful ! So now I see it is also dependant on lumens. Will update soon !

Thanks for the wonderful support you guys !

Sorry for being away for too long, we was too busy in making our system !

We successfully completed the test cycle and now we are a very small local farm selling food to people around us. We are currently successful with Kale, Swiss Chard and Lettuce. More information on our setup will be shared soon.

Thanks again for the support guys ! The forum is a gold mine for people like me.
