Vortech MP40W

The feed mode doesn't turn 'em completely off, they just go reeeeeally slow...

Feed mode on the Gen 1 is 1000 rpm, if you have Gen 2 the feed mode is 500 rpm.

The big issue the guys down here were having with the battery backups during the power outage is that when the battery backup comes on, your pumps automatically go to half of your current setting speed (similar to Night Mode) and hey were not getting enough surface agitation for oxygen exchange for their fish. The guys who also had battery powered airstones did much better.

The big gripe was that the selling point of the battery backup was to protect you during power outages, but it turned out to be a false sense of security.

(I have a MP40W on my 90g and love it! but don't have the battery backup)

I have a MP40W on my 40 breeder and its awesome. Complete overkill but who cares!!!

Guess its time to upgrade the tank.

i like your style wwarriner!

For those MP40W owners, how do you select the wave modes? Is it via a input selection on the driver? Also, if the power goes out, does the wave mode you select get saved or do they go back to a default setting?

There are 2 buttons and a potentiometer on the driver. The potentiometer controls the speed of the vortech and the buttons are to cycles through the wave programs and set the wave profile.

I don't have a battery backup but I believe when the power goes out and it's running on battery, it is the same as night mode. It is a constant flow that is 50% of the max set flow.

If you cycle power and don't have a battery backup, the vortech comes back up, runs through it's boot up sequence and then resumes the previous wave profile. The preset Sleep Mode start time is not remembered. Since the driver doesn't have a power button, you have to unplug to turn the vortech off. I haven't tested for an extended period of time to see if it remembers the wave profile (usually a minute or less to move the pump around).

Thanks. That helps he out on if I either want to use the pump with its built in feed mode or the feed mode built into my controller. With the Profilux controller you can program a socket to 'filter' and then it will turn off the power for a set period of time allowing you to stop the flow for feeding. If the night mode settings do not save after the power goes out, looks like the feed mode option will only work well through the Vortech's driver.
