Aeration will be required both summer and winter. In the hot summer weather refrigeration will be necessary to keep the fish alive.

You will also need chemicals to remove the poison that municipal water supplies contain. Sure Life has a complete line here.

As a minimum you will need Better Bait.

You have no idea what you are letting yourself in for. The tank will have to be cleaned once a week. Under the best of conditions a few minnows will die each night. If the jokers at the local water plant suddenly increase the chlorine or add an unknown chemical you will lose the whole tank.

I fought the minnow tanks for five years as the assistant manager of the local marina. It is no picnic.

If you have good aeration and do about 25% water change a week, probably ok 'till mid-April.

Here's a tip for a red neck chiller...drill a hole in the door of one of those small refridge's preferably an older one that still cools. Through that hole run as much flexible small hose/tubing you can get inside the fridge. Hook it up to a small low volume pond pump and circuate the water through the cooler into the pond...presto you have an effective chiller.

If you are only talking the spring you will have no problem with heat. If you get hot days just add ice. Be sure to neutralize the ice.

Good luck with the minnows.

pm TxPacker4 on here, i know he has a simple set up for minnows that works, and he can keep them for a week or so that way

I've been thinking about doing the same thing lately.
