Adding circulation pump for IM 14 gallon

[mooputingtong]

i currently have sicce 0.5 with about 30% closed cap for lower gph. I feel like detritus is settling on lower side of tank and im adding hydor koralia 240 for better water movement. Will adding extra pump be too much flow?

Evening,

I’m not familiar with the tank dimensions, maybe someone around tonight is that can help.
