not totally silent but very quite low humm. Powerful up to 42 inches with 2 - 90 degree elbows. does cut off at 50 inches of height. Good for short run or to run like my nano 20 high with 10 gallon sump under tank

I am using one of these in a 5 gallon bucket and half filled 32G brutes to mix salt. It has more than enough power in the 5 gallon and adequate power in the 32G. It is pretty quiet for the money, but not silent

I have this running my uv and it seems to be doing just fine and it is nice and quiete

Great little pump. It runs Quiet and cool. Never had an issue with these pumps over the years.

The 1200 works well and it seems to be the cheapest pump I could find that could be run externally. It's been working well for my mixing station for the last few weeks.

Believe it or not I've used this pump as a return on a 40b system for about 5 years now. I got a good deal on it and though it was supposed to only be temporary I liked it enough to keep it as my return pump (have circulation pumps and such in the display obviously). Overall a great pump. It's been very reliable and it's still very quiet.

it doesn't pump to much water but is not the pump fault, i should bought a stronger one

This pump is a good little pump. I don't think I would expect it to power a dual reactor as well it it should be, single yes. I just use it to get water into the tank from a 5gal water change bucket. It works amazingly for that! It's extremely quiet too (submerged in water, you'd never know it's on).

The pump works just fine. It does not move enough water to work well with the dual reactor. The water coming out of the reactor is just barely a trickle. This is not the pumps fault, I should have bought a stronger one.

I bought this pump one, because it said the outlet was a 1" MPT(male pipe thread) two, because it was cheaper than other brands. However I had already purchased the rest of the return line plumbing to work with a 1" pump outlet. When I received the package the pump wasn't a 1" MPT it was a 3/4" MPT so now I have to go and get all my return plumbing to work with the 3/4" outlet. I also contacted BRS before I purchased this pump and asked them about the outlet because the picture they where advertising showed it as a slip outlet not a MPT, while there quick overview said it was a 1'' MPT . I got a response saying they where going to change the picture to correctly match the quick overview specifications. I haven't used the pump yet so it would be unfair to judge the product.
