Triops Longicaudatus Detritus Removal

[Bettabuddy664]

Hello, I know this forum is meant for fish, but this is the only place I could ask this question. For those of you who know about Triops, at what day after hatching could I remove the detritus (the brown little plant pieces) out of the water? I wanted to know because It makes the tank look bad. 
 
Thanks!
