magnetic stirer and dosing pump

I know a few people use BRS dosing pumps and I just bought two for the feeder I am building. Plus they are not too expensive.

Waiting to hear about the magnetic stirrer though...
 
any magnetic stirrer will be fine for the most part. If you buy a name brand like Hanna you'll spend more and not achieve much more, if at all, then what you'd get from a non name brand. I use an old Thermolyne and it's worked flawless for 5+ years
 
The last time I searched Hanna seemed to have the cheapest magnetic stirrers. There are some fairly cheap used Thermolyne, but new looks like about $275. With used... what was it used for? Pesticides? Drug lab? Or something that couldn't harm a reef tank?(or me!)
Hanna new on amazon is about $80.

I am looking for the same thing the original poster is looking for, but it's been years since I've been in a lab and I've never purchased a stirrer before.

For the electrical section of the stirrer I wouldnt worry much what it was used for in the past. Now the glass ware and the stirrer that is going in it, that has to be new...no choice there.

Pardon my ignorance, but is there a reason why food can't be dripped in from a container with an airline as opposed to using stirrers and pumps? I'm considering starting a NPS tank and want to know what equipment is a "must have" in order to be successful.

You need a fridge to slow the rate at which the food spoils.
 
A fridge/freezer I have for fish food, phyto, etc.

Would the NPS food mix do okay if dripped into the tank over a period of 10 hours or so? I figure I could switch containers once so there'd be a steady supply of food for most of the day.
 
It wouldn't stay mixed. All the solid stuff settles to the bottom and would either clog the tube or, you would dose all the solids in the first part of the day, and then only dose the green water the rest of the day.

Also, how would you slow the drip? If its a valve, that will most definitely get clogged.
