I don't mean to sound like a "know it all". But please be very careful if you decide to ask his advise. . . 85-90% hatch rate? If he produces 700 fry per spawn, then his claim would be true. I know for a fact (I used to count them) that 4 month old females (smaller females) lay about 700 - 800 eggs while fully grown can lay over 1300 eggs.
For his method to work, you need to use a very clean tank and water. Otherwise mold will kill some if not most of the eggs. His method can be used for known egg/fry eaters. . . artificial hatching. But why risk it if you have a known good father.
Fertilized Eggs on the floor may hatch IF mold doesn't destroy it. When artificially hatching eggs in a bowl, some eggs will fall on the floor.
Again, I'm not saying he is wrong. I'm just saying he is NOT THE BEST and his methods are definitely not for new breeders.
