REGARDING ISSUE WITH PHOSBAN 150 REACTOR

[acepumping]

Hey, got a question for ya guys, just started using pellets in a Phosban 150 reactor, my question is,

Should i leave the red little protectors in??
i put in the screens on top of them.

my thing is i only have a 250 GPH right now for the night, but only 1/2 the pellets are turning,
so i am purchasing a 350 Gph tomorrow,

my net water volume is also only 65 Gal-- with 100 ml of pellets for the first time and to get it going

please let me know your thoughts on if i should cut those red trays out and just use the screens

thanks
