growing the rots in the hatch tank is a bad idea. it will add to much waste and ammonia. only need to add rots when the babies hatch.
i dont use alot or any parent tank water for my hatchlings. all you need is aged saltwater. aged as in made 24hours old. i always buffer my rodi with a pH buffer so its not so harsh on the fry. it seems to help. so when i fill up my rodi tank, i'll add the buffer and mix it up with a powerhead for a few hours then add the salt. i heat it and let it mix for a day before i use it in the fry or any tanks. sometimes ill add a little parent tank water if its clean enough.
when i fill the fry tank with water, you just want enough to cover the pot or tile that you have. so in a 10g i use, i'll add like 4 gal of water. i would keep the babies at a higher temp than the parents. i keep both of mine at 84, but since your main tank is 80, i would keep the fry tank at 81 or 82.
as for the rotifers, if you want to use the rots that you thin out in your main tank thats good foood for the corals and fish to eat. i do this sometimes. just make sure you strain it. hehe. the bucket of rots usually get high ammonia. so i would strain them hen rise them a little with fresh saltwater.
if you have a problem with keeping the temp up, then use a controller and a bigger heater. some of my tanks i use a 100 or a 150 heater with my rkl. the longer heater will help keeping the water warmer for the babies. i never trust heaters to remain constant so thats why i use a controller for the heat. i found a good deal on a rkl so i bought it. you could use a jbj heater controller or a whatever.
