Hi Roger can you help me with my 9004. Main thing though is I bought it not really realizing it wasn't made for a sump, I have it in 9.5 inches water but it's sitting on the sump floor. Will it still work properly since water comes out the bottom. I don't want it in dt and I doubt I can return it since I already placed in the tank..waiting to here from brs for that. Any other tips for using it in sump? I love how quiet it is compared to my old one and with my sump being on the small side most won't fit. I would love to keep it IF it will work properly. I'm starting to get some dark tea skim (installed yesterday afternoon). Sorry for the rambling!
