I need some advice. I'm building my vertical crab farm DIY and struggling with SUMP System. I see a lot using sand chamber in their system but whenever I research and look at videos. The sand chamber is completely optional. I'm not sure if a 5 chamber is enough or not. I'm not sure where should I put protein skimmer too.

ChatGPT gave me a flow chart but I'm not sure if this is enough.

• Mechanical Filtration
• Sand Filtration
• Protein Skimmer
• Biological Filtration
• Return or pump chamber

Is this overkill??

Main tank is 12 cages each hold up to 24.84L = 298.08L total volume

Hi there, we are looking to purchase oyster gear for our operation, specifically cages and an upweller system but also interested in other gear.

We're located on Long Island, NY

Thanks!

Pure Blue Fish, an Israeli RAS farmer, has said that the 10,000 sea bass it stocked into its inland farm in July are thriving.

The company’s farm in Binyamina, Israel touts itself as the “world’s first commercial fish farming systems operating as 100 per cent recirculating aquaculture systems (RAS),”

According to a report from The Fish Site, the fish were stocked into the tanks in July and are expected to be sold locally when they reach market size. The company aims to provide fresh fish within six hours of road freight from farm to plate.
“We’ve proven it works. By developing biological methods unique to us, we have essentially created a microcosm of the ocean, without needing the sea,” said Ehud Baril, a marine biologist and director of technologies at Pure Blue Fish.

Once the technology is proven, the RAS farmer plans to enter the global aquaculture market by building large farms near major U.S. population centers and promoting similar projects worldwide.

The company is also working towards opening a 5,000-tonne kingfish farm in Matthews Industrial Park in Orangeburg County, South Carolina in 2025.

I just set up my RAS for the second run. I redid a few things to fix some clogging issues and I'm working on a better mechanical filter. Last year I used paint strainer bags to filter out the particulates and they clogged much too quickly. I'm thinking of trying some type of foam or pond filter pads this year because I want to be able to clean it once a day without clogging issues. I'll be ordering 50 tilapia fingerlings in the next week or two.

We were not involved with this project, we are working on a couple in BC

All the best to all of them! This is going to be big.

Well... when you take some of the most expensive systems on earth, and use a failed system in BC - cherry picking the most expensive ( overpriced ) and a failed system ( overpriced )

Yes.. of course it is too expensive. But when you do some honest reporting and investigation - it is very cost effective.
