At what point is it safe to move fry to a grow out tank?

Here's the story on these guys. They were laid, hatched and became free swimming in a twenty gal. with mom and dad. After a week of free swimming I moved all the fry into a ten gal. Filled with water from their original tank and the filter from their original tank. Skip ahead three weeks and they are growing like crazy, but so is the ammonia. I don't think the filter is keeping up. I have an 80 gal. bow front set up for a grow tank but is it to soon to put em in it? Oh ya they are angel fry.

no it should be fine as long as the water in the bow front is ready. make sure the intake is covered so none get sucked up. and watch them grow like crazy with more room

the more water changes the cleaner the water and the faster they grow
