Anyone know anything about these pumps? Just as bad as the other RIO pumps or are they better?

TIA

I was told they were better, so I bought one. Man! Does that thing ever put out some current! 8O

I just got one. Either I am missing something or there is not allot of current. I have the 820 model and the current barely reached the other side of my 3 ft tank.

Is there a setting I am missing?

I can't remember which model number I have, but it causes a sand storm on the other side of my 4" tank. (48x32x24) I had to put a layer of heavier grade sand on the other end to keep in it place. That is with the little flat diffuser installed. Without it, it would be impossible to use in that tank.

People are saying the new RIOs are good pumps.

If you ask me a reputation as bad as RIO has cannot be fixed overnight as some people want to belive. Time will tell, but you won't see one in any of my tanks for a few years.

I removed the directional output of the pump and placed the pump horizontaly and now I can see some flow.

Not exactly enough of what I wanted to achieve but its ok. I was hoping to get enough current low in the tank to get the detritus to be blown back up so the overflows can can dump it to the sump to the skimmer.

Next on the drawing board........

Ive been running the 620 in a 3 foot tank for a while. Its a good pump so far. I have it blowng directly on some Montipora colonies on the opposite side of the tank. Polyp extension and growth HAVE increased.
