| phyto i wash it everytime (jars and rigid tubes). Had them crash a few times because of it. For my phyto, I let go for 14 days. And it gets really dark, but I add 5ml of essential elements and I use a 4L pickle jar. They work great. Easy to clean. Some people use miracle grow for their phyto,but does not as green like mine. Use micro algae grow from aquafarm.
As for rotifer. You need to start in the dish that the phyto disk came it for 24hrs, then add them into a 500ml bottle and then I think after 48hrs into a 5gal tank.
phyto disk add a little of phyto and rotirich ...not much
500ml get the bottle a little green and add rotirich also.
