pump for my bait tank

[Sdspeed]

I'm building a small bait tank 3 to 4 gal. Do You guys think this unit will move enough water. I figure I 'd stay with a 12volt unit so I don't have to carry 2 batteries or run a volt drop inline to the water pump to slow it down. Want to build a tank that will fit in the hull in front of me since reaching backwards for bait is a bitch on my body.

DC 12V 6.5L (100GPH) submersible WaterPump

Price:

$21.50

Is it designed for salt water use? Why not a bilge pump?

I would probably stick with an attwood, or rule pump. Is it going to be a through hull bait tank system (probably, by the looks of the pump). Also, if your going to put the bait tank in the hull vs on the deck, make sure you don't take on water and sink.

That would work.

I think a 500GPH at 12V would be too much flow. You would need a really big drain to be able to keep up at 100% duty cycle. Even my rule 360 @ 6V can barely keep up with a 3/4" drain. I'm planning to changeto a 1.5" soon.

That's why this pump at 100 gph on 12v should move enough water and I'll only have to carry 1 battery to operate it and my FF.
It can be submerged in saltwater but doesn't have to be.

This is the one I have used many times with no issues with flow or anything. I think many of the bait tanks use this type of pump. I have seen some using 360GPH but for the most part this one

If you install a spray head that you can control the amount of spray you can cut down the flow, but also think of this. Dines use a lot of Oxygen and the water needs to be circulate well for them to stay alive. Most will use timers to control the inflow so that the pump is not always going. Trust me the 500GPH pump is worth it and at walmart is often only about $20 on it's own.
