Need to Start A Rotifer Culture

Hi all,

I'm looking to start a Rotifer culture, Can anyone hook me up with some starter.

Also, Any tips / Advice would be appreciated.
 
I might be making a bad assumption here... that he'll be running an algal culture to feed the rotifers... (if not, why bother with the rotifers?). If so, I've consistantly gotten much higher nannochloropsis culture densities using tap water. Years ago, Rick and I did some experimenting trying to figure out why his cultures, seeded from mine, weren't as dense. Problem was solved as soon as he switched to tap water...
 
That's interesting.
You'd think some contaminant or something they treat the water w/ would make it less hospitable, rather than more.

The tapwater is used in the microalgae culture, Mac.

Whenever I use tapwater in a brightly lit aquarium I get a noticeable increase in algae growth.

I'm pretty sure the nannochloropsis (microalgae) uses up most of the tapwater contamininents before being fed to the rotifers.

BTW- water used in these cultures can be sterilized by placing it in a microwave oven. ;)

That's what I used to do when trying to grow the Nano... what a PIA! :)
Take a bowl out of the tank, nuke it for 10 minutes, let it cool, mix up your nutrients, add the algae (or decant from one of your other cultures..).
Never had good luck w/ that (bacterial problems, lotsa clumping), and the wifey hated green bottles on the window-sill (fortunately, back then, she was just the g/f, and I didn't have to listen :D ).

Tap water's been working great for me.

Reefermac, I thought it was the other way around (you listen when she's the g/f, then all bets are off). In my case I'm the one with the green bottles and my husband just laughs...

dalbrecht, I could offer you some of my culture, but it's a little low at the moment (and seriously contaminated with brine shrimp!). In a month I should have plenty volume and the bs removed if you can wait that long.
 
Hi all,

I've been offline for a few days.

I can wait a while for the culture starter. I use aged tapwater + miracle grow for my phyto culture. Whenever anyone has some available just drop me a PM.

I can wait, I decided to throw out the first batch of eggs so that I would have more time to get things in order.

I heard there were some issue's w/ using terrestrial fertilizers for the marine phytoplankton strains... Not so much for the algae (NPK, is NPK :D ), but rather, the resultant dosing into the tank - some metals included in the terrestrial fertilizers were at risk of accumulating in one's tank. This was presented by the same folks making 'proper' phyto food (take it w/ a grain of salt, tho I trust FAF), and was directed more towards folks raising larvae on the stuff, however I thought it worth mentioning that little nugget my brain decided to retreive at this moment.

Mac,

Thanks for the tip. It could definately be an issue.
Miracle gro products contain chelated copper.

Since Copper has a positive charge. It will be attracted to high CEC materials within the aquarium including any phosphate remover currently in use. I typically run phosphate remover (Al or Fe based) so I think that's why I've never had a problem.
