Great post! I’m also trying to culture phyto and pods for a future mandarin. My phyto crashes all the time and I’m considering doing two pod cultures instead of one pod and one phyto. If you’re not culturing phyto, what do you feed the pod cultures?
So this is exactly what I went through that led to a very important discovery.
I was also getting tired of culturing phyto. With the pandemic, it was very difficult to keep it sterilized all the time as there was no alcohol anywhere.
I came across a post from someone who has been culturing copepods en mass for a decade and something struck my eye.
The person didn't feed their tisbe pods phyto. In fact they had phyto as a secondary food source behind detritus and fish flakes as the primary food.
My tisbe culture was weak when only using phyto so I decided to give it a shot. I tried a hand full of different foods and the winner was reef roids. I believe this is because reef roids is just ground up rotifers (which all pods go crazy for).
Currently for my tisbe culture, I dump in maybe 1 small cap of phytofeast by @reefnutrition (normal, not live), and 1/8th teaspoon of reef roids (twice for 1 harvest). My weekly harvests are 10x what they were with phyto.
For apocyclops genus copepods, they prefer detritus in some way shape or form. These are your tisbe & apex varieties, the ones that live on surfaces (rocks, glass, sand, etc).
For tiggers, you will have to feed phyto, they require it.
