what a peice of junk

[organicreefer]

ive been meaning to post about my dolphin dp1200 for the last few weeks.this pump is the noisiest peice of shi* i have ever had the pleasure of owning.ive had a few rios too.

the final straw,why am i posting now? the thing just quit working for no reason . i took it apart cleaned itcant see anything wrong it just stopped
good news is im pretty sure dolphin will be willing to help.but even if they give me a new pump,im selling it.this thing just plain sucks ,imo;; dont waste youre money........................

just swapped it for my skimmer pump,couldnt stand the thought of putting one of my old rio's on this tank;) anyway,its a mag 18, 600gph more and 5w less,cant hear it (well barely), proven.........just a little comparison for ya............please dont waste youre money on the dolphin

this pump will go back on my skimmer im ordering a mag 12 or 9.5 havent decided yet

Ill tell you what I found out about some of the dolphin pumps Organic...there is a ring inside their pumps (all of them except the AM3000 i think) and the ring helps route the water but is NOT needed...My AM2100 is doing the same thing as your pump is doing....so I called Dolphin...and explained...he is sending me out a new ring and told me how to replace it....he said I could leave the ring out but will lose aproximately 10% of the pressure. If I replace this ring and the noise comes back, then im yanking that piece of crap ring out and leaving it out.....Call up dolphin and ask them about it....the ring is a VERY cheap part so even if your out of warranty which i doubt...then it shouldnt cost you much to fix. HTH!

its not a AM itS one of the submersible "sen" type pumps.it was always really loud.i was planning on replacing it just for that reason.its so loud its not only annoying its embaresing i think a couple people looked at me funny for having this loud aquarium exhibit in my living room its so much quieter now there is no way im using a dolphin submersible sen ripoff again i LOVE my ampmaster though,best pump ive ever had thats for sure;;

Nothing wrong w/ Mag pumps either(IMO). I've been running Mags exclusively since I've been in this hobby. Not one failure yet, and very quiet.
