I was looking into the 4800 series flows 3800gph @ 5' head and 250 watts. Seems like pretty good flow and wattage doesn't seem that bad. Couldn't find anyreviews on them
I use two Hy-Drive 4000's,one which also is split and goes into my bioreactor. I have this setup on my 535 gal. ray tank,and yes for the GPH you get...can't beat 200 watts! Oh Yea! these pumps keep the water right at the temp. that i need it to be,pretty sure my heaters have never come on-that will save you a lot on your power bill.
