I've been thinking about this a lot. I have some of Inve's MIC-F, and I recently bought with very expensive shipping, a couple ounces of Fritz's Turbo start. Now I realize that the bacteria in MIC-F are supposed to populate the gut of the larvae, and the Turbo Start is more for ammonia control of the tank, but the MIC-F is supposed to help with ammonia control as well, so this expermient was about survival and ammonia control.
I used three 15 gallon tanks filled half way, after my usual routine of cleaning, with 27 ppt saltwater, new but aged 24 hours. All three had identical 100 Watt Eheim Jager heaters, set to give 81F water, and an airstone. All three were bleached at 1 ml per gallon for 24 hours, then dechlorinated with sodium thiosulfate, and tested for chlorine. The first tank was dosed with Fritz's Turbo Start according to directions, the second tank got MIC-F according to directions, and the third tank was a control tank. These bacteria or spores were added September 25. Also added on that day to each tank was 100 ml of live isochrysis, because I had it and I'm not sure why, but I doubt that it hurt anything.
The following day, I hatched a small nest of A. ocellaris in a bucket. I distributed them 70 to a tank, by scooping 10 larvae into a small plastic cup and delivering 10 to each tank in succession until I had 70 each.
I fed each tank 500 ml of my enriched rotifer culture which had 900 rotifers per ml. I filtered out the rotifer culture water and only fed the rotifers. I put in 10 drops of RotiGreen twice daily or as needed to each tank. Each tank was lit by 12 inches of a cool white LED strip suspended 12 inches from the tank, probably 18 inches from the water. 14 hours day, 10 hours dark.
On September 28, I had 23 dead bodies counted on the bottom of the Turbo Start tank, 27 dead in the MIC-F tank, and 23 dead in the control tank.
The next day, I found it easier to count the live ones:
Turbo 17, MIC-F 10, control 7.
The following day,
Turbo 17, MIC-F 8, control 6.
There were no further losses until day 7 when the experiment was ended, and all remaining larvae were merged into the TurboStart tank. It's day 12, metamorphosis has been going on, and all appear well.
