Coarse sponge harmful?
I have a tidal 55 and a dual sponge hygger. I was using half of a hygger sponge on the bottom of the intake to keep sand and stuff out. I just got an optimizer to try to make it shrimp safe. I ordered the prefilter sponge with it. It’s really coarse and really, really scratchy. I’m also not sure baby shrimp wouldn’t get caught in it. Will it hurt my dude? He likes to hang out in the plants beside the filter and sometimes squeezes himself in. Could i use the other half of the hygger filter to cover the optimizer?
