I got several cultures going. I started with a 2 liter bottle with pods collected from tide pools on the Oregon Coast. In the bottle was some macro collected in the same place. These things are really almost bullet proof.
As of today I have the original 2 liter bottle, 1 spaghetti sauce jar, 1 jelly jar, and 1 salsa jar all in the kitchen window growing the little buggers. A couple times a week I add a few drops of Phyto feast. The water should be slightly stained green. With the natural sunlight this should "bloom" the phyto. I also add a few drops of selcon when I remember, probably a couple of times a month. I always have a very small thin strip of nori floating around on the top of the water. They seem to gravitate to the nori. Whenever i disturb the bottle / jars I can see them scattering from the floating nori. In the Jars I also have some chaeto from my fuge to give them a place to hide and breed. About once a month I take the oldest jar culture and gently set it in the fuge, with the top on at first to sort of temp acclimate them, then take the top off and set the jar on the bottom so they can swim out of the jar. Them I will pour about half a jar from the original 2 liter culture into that jar, refill the 2 liter with fresh saltwater and keep going.
