Any ideas on how to concentrate phytoplankton

[ezhoops]

Looking for ways to concentrate my phytoplankton. Not looking to create a paste but to create a more concentrated thickness in a liquid form.

I know the major companies use a centrifuge, but alas I do not have one.

I welcome your ideas that you have tried and that have worked.

Well I was culturing phyto for several months and finally stopped since my cultures quickly out grew my needs. I dont have anyone else around that would use it and was throwing more out than I was using. I would love to see some pics of your setup. I was thinking about getting back into it again.
As for your question I wouldnt think it would be that hard to make a fuge to spin down the phyto. What are you culturing in?

Centrifuge

If you are lucky you can get an old used working centrifuge on ebay for pretty cheap.

Ok, I understand that a centrifuge will work, but also keep in mind that most centrifuges spin very small amounts of liquid (50ml is a big one) I'm looking to concentrate gallons at a time.

The recommended spin is 5000rpm for 5 minutes

as for the net, I just don't know how well it would work. it catches and strains phyto but you have to add water to rinse it off. So, I guess its a start.

just let it settle in the bottle and pour off the water part once its settled
