Osmolator pump questions

[au01st]

I'm DIYing an ATO for my 24g Aquapod (would love to purchase the whole Osmolator setup but as a new college grad without a permanent job yet, I have to save where I can) and I plan to use the Osmolator pump from Tunze for a few reasons: 1) it fits through the lid of the 5g container I'm using where a MJ or other wont fit, 2) it can handle the head pressure of 4ft where an Aqualifter won't, and 3) the low voltage vs using a 110v pump.

At approximately 4ft, what GPH will the Osmolator pump push at either 9v or 12v? (I have both in the appropriate amp ratings just sitting around)

Is there a min or max amount of time the pump should be on per cycle?

Is there a max recommended number of cycles per day?

I evaporate a little over a gallon per day, and I would like to set it up to turn the pump on every 2-3 hours, I just don't want to burn up the pump prematurely.


Thanks!

Our controller won't let the pump run more than 10 minutes. The pump doesn't really have a GPH rating, at 4ft it pumps about 1.5 gallons in 10 minutes at 9V and about 2 at 12V. This is only a casual observation of how much it can drop a reservoir before the time out occurs and not something I have a definite measurement on. It pumps roughly 1qt per minute though.

The number of cycles isn't a big issue.

Awesome, can't wait for its arrival.

So I finally got this thing hooked up after converting the output to 1/4" poly line, and man, that pump is a beast, especially for its size and price! I actually had to put a valve inline because it was so powerful it was causing splashing where it enters the back chamber of my Aquapod. The pump is just loud enough to be audible to know it's working, but not so loud that it's annoying. Best of all, it fit perfectly in my container's opening with .37mm to spare (I pulled out the micrometer b/c I was curious how close I came to ordering yet another reef-related paperweight).

To think I was actually trying to compare this against a MJ-1200 is just unfair. Kudos to Tunze for making a great product!

Thank you!
