700 gph pump

[spawn]

I had a rio 2100 that was giving me 690 gph @ 1' & the impeller seems to have gone on it. Contrary to popular belief this pump worked awesome for me, it was quiet & contributed sfa for heat. I can't find one in town right now & am using a spare rsm thats only giving me about 600, not enough. Just wondering if anyone can recommend a good comparable. Thx.
