Hi all breeders;
While Im culturing my phyto and rotifer for 2nd batch, I did extensive studies on the good World wide web. I stumber upon some problems that need answering, hope you guys can help out.
Phyto:
1. While it is easy to see that it is growing, but it crash at day 6 and pale to clear water in just 2 days. Many suggested spliting at day 7. But my phyto culture is not that dense when it crash, but then I bubble at a low rate, now I increase it to 20 BPS. Question is that should I add F2 media on day 7 if I want the phyto to thinken in concentration presuming the F2 media should be use by the phyto in day 7.
2. There is a layer of whitish scump in the bottom of the coke bottle, should I filter it out or is it all right to keep it there.
Rotifer:
1. I have problem knowing if the culture has crash. When it is bubbling, denitrus are suspended so I saw particles in the water column, once I off the bubble and let settle, on the lights, I dun see rotifer attracted to the lights, does it means it crash?
2. I get denitrus and gunk on the side and bottom of the 1.5l bottle. I presume they are to removed so I change the bottle every 2nd day, and rinse out. They are not rotifer by any chance right?
3. I keep a batch of gunk in my fridge hoping there is cryst in them that I can restart if I crash, is that true.
4. I'm using IA for now since I yet to get my phyto going, since IA is dead, how I know if the gunk at the bottom are from the dead phyto or waste from the rotifer.
Hope good samitarians can help.
Cheers.
