try to fit a sponge over your filter intake. that'll keep 'em from getting sucked up. the parents will guard the eggs, and sometimes even eat them. it may take a few tries for your parents to get it right. you will hopefully notice them "fanning" the eggs. this is done to keep the eggs getting good water circulation.
It's debated whether or not you should remove the eggs and put them in a breeder, or let the parents do their thing. I will be getting some GBRs in about a month and will hopefully be seeing the same results as you! very awesome that you got these results!!
