phytoplankton culture help
 

ok i got a setup from a member on here, its the whole setup, 3 gallon set up my ? is do i fill it up all the way with saltwater leaving enough to put 500ml of phytoplankton in and the f2 fert, and when i split do i leave half in and put new salt water in and the fert to keep the culture going, and do i have to put the split cultures in the fridge, sorry guys a lot of ?? i just don't wanna mess things up
thanks

I'm assuming that you are talking of the mamaroo phytoplankton kit.

and the air line and light.

I wouldn't fill it to the brim.
Leave a few inches for the bubbles to pop against other wise it will leak unless you fully tape the lid on to it. If you do that, you will end up with a sludge that forms behind the tape and has to be cleaned everytime you open it up.

yeah pretty much
read up on the amount of f2 required. It's not a lot.

I always have, not too sure if you must.

is it going to be ok if i have it in my fish room or does it need complete darkness, cause my sump light is on 18hrs a day

yes it is the mamaroo kit

To maximize growth rate, light the phytoplankton 24/7. It does not need a period with the lights off. The phytoplankton gets its "dark" time as the cell circulates in and out of the inner parts of the culture. I'm not sure what species you have, but typically 100 umol (PAR) is a conservative light intensity for microalgae.

Also, this website details the F/2 medium and gives some information about general algae culture.

F/2 can be purchased in bulk from aquatic ecosystems. The 1 gallon jugs of part A/B would last most hobbyists a very long time. To make it easy measuring-wise, you can make pre-mixed "stock-solutions" and keep them in your fridge. This would allow you to add (for example) 1 mL of stock solution per L of culture to achieve the appropriate concentration.

so i have to keep my f2 in the fridge , and why does everybody say 16hrs light and 8 h darkness iam confuzed

I always get best results 16 hours on, 8 hours off.

myka do you keep yours in the fridge too

The f/2? Yes. I haven't had any luck with f/2 though, I think I got a bad batch. I've been using Miracle Grow and Kent Essential Elements, but I worry that f/2 might make the phyto more nutritious, so I'm going to order new f/2 and try it...eventually.

I don't put any phyto in the fridge.

Yes you fill the reactor with fresh saltwater mix
Then you add the 500ml included and fertilizer
:)
When is time to harvest you can split the half
The rest you can keep it in fridge or sell it ;)
