What process do you use to sterilize sea water? Im guessing the first step is carbon filtering the sediment. But is the water then heated to 150? Or can you chlorinate and then oxygenate?
Hi Gerald! thank you for your questions! Sterilized seawater is needed because regular seawater taken from the ocean will have phytoplankton and other algae in it. When given ideal growing situations all those other things would grow in the water and ruin the kelp sores that we want to grow. The sterilized water is still salty but free of anything that could mess with what we want to grow. You can sterilize with an autoclave, using bleach, or with particle filters and a UV light. As for nutrients, because we sterilized the seawater there are no more nutrients for the kelp to grow. We need add those nutrients in so they can grow. there are lots of ideas and peoples thoughts on what is best needed for the kelp. Generally speaking you need nitrogen and phosphorus plus trace amount of metals and other things. this link might help: ncma.bigelow.org/PDF%20Files/NCMA-algal-medium-ES.pdf Lastly the temperature should be anywhere between 5-10 degrees Celsius. You can look for small aquarium chillers online. Amazon has a few that are good.
@@herringgutcoastalsciencece419 thank you so much for your time. Your video has launched me into a flurry of action. I have a drone with FLIR so I will be looking down on my farm area to get the right temp. I could also just use a fridge I guess.
This is such a great informational video to bring a lot reading to life, thanks so much - looking forward to the first steps of my hobby nursery

interesting tutorial! If you don't mind, at 6:25, you describe filtered sea water with nutrients...what are the nutrients?
We use Guillard's f/2 concentrate 14x with silica from Algoid Technologies
If you are in Florida where can you find fresh kelp to germinate?
@Patrick Burnham Are you willing to sell some to me for reproductive?
sterilized seawater?
added nutrients..from where
what temp was the aquarirm and what brand has cooling? thanks..just a few holes to fill
