I just had four of my nine bottles of nannochloropsis and Tetraselmis crash. I have about ten gallons of fairly dense rotifers going right now and there is now way I am going to be able to maintain them with what is left. I will have enough phyto to enrich small batches of them before feeding to the dottybacks, about 150 at five days. Is there any readily available food source that I can use to keep the large culture of rotifers going. Overnight air for some concentrated phyto isn't an option. I'm afraid I'll like it too much and this venture is expensive enough already. Yeast, V8, any ideas from someone keeping the cultures going on other than phyto.

You can get RotiRich from Reed Mariculture in smaller quantities of powdered form (low shipping). It's a yeast and vitamin based rotifer food, very good stuff. It will foul the water more quickly than phyto, so be careful. I made up a gallon and maintained 2 10 gallon cultures very densely for almost a month with it, I think it was around $20 landed, so it's not going to kill the budget too bad.
V8 and Yeast will also foul the water quickly, I've even heard of people using powdered spirulina and vegetable oil...but I aint putting that in MY cultures!
Good luck,
Jason

V8 will make the ciliates bloom if you have in your cultures.
Get this from the grocery store:

I mix with 1 liter of water and feed about 30 ml of the solutions to 10 gal. with about 100rots/ml. This is what I use as staple for the rots, enriching is another story.

Thanks Jason,
I used Rotirich once before. I crashed my culture, I'm sure it was my maintenance schedule that caused the problem and not the Rotirich, I'll have to see if I have any of it left. My other thought was to put another shop light on the other side of the remaining bottles to increase the light level and maybe speed up the growth of the phyto. Not sure about that either, maybe the increase in light would do more harm than good. The thing that really irritates me is that I'm pretty sure I know what caused the crash. I had been using a bad bag of salt that had much higher alkalinity and Ca levels for my phyto and rotifer cultues. Well, I guess when I started a new bucket of salt the phyto didn't take the change all that well. I wasn't even thinking about it when I took the 2/3 out like always and just filled it back up with the new salt water. Thats all I can think of anyway.
