Does anyone local have rotifer culter they would be willing to share a teaspoonful of, or anybody have rotifer cysts ofter a crash????
Or anyone know of any local retailers/moody garden/ houston zoo/ aquarium resturant that would be able to help start a culture.
Or would anyone be willing to split an order of rotis and live phyto for culture experiement??

Darrin, are you adding any type of fertilizer to the phyto?? What species is it?? What is their light cycle??

REEF: I've never seen any at LFS. We(Moody) do not have any. We(Kemah restaraunt, i just got hired their, start in Jan.) do not have any either. I'm pretty sure downtown doesn't. I might be interested in splitting an order of cysts with you. How soon would you be wanting to do it??

http://www.aquaculture-supply.com/ This place has pretty good prices. You know of any other online places??

www.brineshrimpdirect.com Has decent algae prices. Want species do you want?? I would be wanting Nanochloropsis.

is it bubbling too much? Is there foam forming at the top of container?
And what is spec grav?
I am only trying to guess at the cause. Hopefully we can get your culture booming if we try to address all possibilities...

Are you culling enough plankton out?? Nanochloropsis is usually pretty tough.

it usually does not live long enough to cull out enough.... i got 2 -2liter bottles living out of 10. what does foam and too much bubbling have to do with it? i didnt know that was a problem....

As long as you have enough air rolling to keep all of the phyto in suspension then your ok. Is the water temp staying constant??

per JOYCE WILKERSON

Foaming is a result of 1. too much aeriation,2. older cells overdue for harvest, 3.damaged cells........ or the overaeriation could be fracturing cells.
Not enough aeriation will result in all cells not getting enough light. And can also result in ph problems which goes hand in hand with not enough CO2 in your culture to help feed them algae cells (yes I used the word them)
I would say there could be a contamination problem too, it seems like your busting your ********* and not getting the results you should.. 8O
I would try a new culture in one bottle, start a whole new clean culture and see if it takes off, but I wouldnt use a starter from one of the established cultures, if the starter is contaminated then you would contaminate the new culture.
Is there any chance the greenwater could be contaminated with rotifers that are eating the algae faster than it can grow..
I hope this helps....
Thanks for helping this thread along. I am learning more from this thread than I ever expected when I posted it...

p.s.

P.S. 10-15 bubbles per second per WiLKERSON, I would say whatever makes the whole culture slowly mix is enough...10-15 per seconds seems like alot, but i think tinkering to get right amount is in order, adn she recommends plugging the top with filter floss to keep contaminates out..
Sorry took so long, I am trying to work and reply

If there were rotifers in there, then there would be no greenwater left. So I don't that is the prob.
