rio 32 hf

hi folks would a rio 32 hf split into two return lines at 5ft be enough flow for a 125 gal fowlr with a 45 gal sump. the chart on box shows 1300 gph at 5ft ran it with a sicce 4.0 and overflows were fine but got a ton a micro bubbles in sump/tank even running thru 100 micron filter socks and a sponge. turned of the sicce and micro bubbles seemed to go away

Based on the numbers (if you believe the OEM numbers) it should work fine. The reviews all seem to point to the noise that pump makes. I've never had one so can't comment on the noise, but that seems to be the common complaint. I have two Eheims that are very quiet but twice the price of the Rio. The small Rio's I have owned have been workhorses.

I think the pump is actually quieter then the sicce the water level In the tank did drop about 1/4" with just the one pump. Just not good at looking at the ripples in the sump and judging flow. Right now it is the Rio is reduced to 3/4 from the 1"output then to a single return line with a dual nozzle. If I just use the single pump I will run 1" into a Y then goto 3/4 into the bulkhead that should keep the flow higher I would think
