My tank overflows to my basement sump and I keep all of my equipment downstairs including my doser which I have not been using very long. Today I noticed a large ball in my coralbox 3 compartment dosing container. I think this is mostly due to my cold basement but also due to not stirring enough (my fault). I was wondering if the DC Micro Pump would hold up to the Alkalinity Supplement (Seachem Reef Fusion 2) or is there a stirrer/mixer I could run off the USB/Plug on my Hydros Power Strip? Thanks

I would say to use a stirplate since it would be pretty harsh on a pump. Amazon has a few cheaper plates available like this one (INTLLAB Magnetic Stirrer Stainless Steel Magnetic Mixer with stir bar (No Heating) Max Stirring Capacity: 3000ml INTLLAB Magnetic Stirrer Stainless Steel Magnetic Mixer with stir bar (No Heating) Max Stirring Capacity: 3000ml: Amazon.com: Industrial & Scientific) but none I could find that are 5V/USB. But you could easily plug this into any 120V plug on your WiFi strip.

Here is another option too:
JOANLAB Mini Stir Plate Magnetic Lab Stirrer with Stir Bar,Magnetic Mixer 3000ml JOANLAB Mini Stir Plate Magnetic Lab Stirrer with Stir Bar, Magnetic Mixer 3000ml: Amazon.com: Industrial & Scientific
 
It is hard to tell from the description but is
the stir plate a simple off/on where the 120v outlet would make it controllable?
Also,My wife said she used magnetic stirrers in lab (chem engineer) and they frequently needed a jump start to start spinning. Anyone using these?

I'm going to buy a stir plate and try to wire one into a drive plug.
 
I bought the Intllab Jeff recommended. The control under Generic Output plugged in to wifi strip is working well early on. A bit noisy at times but it is in the basement. Also, a little concerned about ceramic coating on magnet in Seachem Part 2.

What’s the power supply info on that stir play? What voltage and current does the supply that come with it have written on it?

@JeffB418 Is that 2A rating with or without heat sink, do you know?

@kl3377 can you get an actual current draw reading from the stirrer under normal operation?

I don’t think it requires a heat sink. It’s high eff (only 5% loss) plus the entire thing is potted with epoxy which doesn’t conduct heat well anyways. The 2A rating is only a max rating, the power supply on the stir plate is rated at 1A which I would assume is much higher than what a small fan/motor would draw. If you connected it up to a hydros with this step down converter you should be able to see the power draw in the hydros app as well. Overall nothing stands out to me that would be a risk.

Never gave it much thought before, but I assume a mag stirrer has no Stall Current, or very little increased stall current?
 
I only have this Amp/Watt meter.IMG_4958.jpg
Stirrer set on Max (Normally run it at 1/2) - 1 Watt - 0 Amps Register

For Comparison I plugged my skimmer in.
Vertex Omega 180
22 Watts - 2 Amps
