Bait Tank Quick Start

Terms | Tank Preparation | Electrical Setup | Filter Setup


The Grayline Oval Bait Tank you have purchased is a result of years of working with a variety of forage fish both in fresh and saltwater. We have seen a need for a "better system" and believe through many hours of design and redesign, The Grayline Tank Series, both the oval and round series, is one of the most efficient systems available anywhere today. The following directions and suggestions will aid you in keeping your bait alive and healthy for many enjoyable hours of fishing.


  • After washing the charcoal bag place on top of the large hole.
  • Put the 1" black foam pad on top of charcoal
  • Precut the supplied blue white filter material into rectangular pieces slightly larger than the black foam pad. Place all but 3 of these in a plastick storage bag for later use.
  • Prewet the blue white filter material prior to placing it in the filter box. (makes it easier)
  • Place the 3 layers of the blue white filter material blue side up, on top of the black foam pad.
  • During use, when the top layer of the blue white filter material becomes clogged with scales, start at one corner and "jelly roll" the soiled layer up and when you have time wash it out and have it ready before the next layer gets saturated with scales. The next layer will instantly be filtering any secondary debris.
  • NOTE: Should the black foam pad become clogged, shut off the pump momentarily, allow any water above the pad to drain down, then remove the charcoal, pad then rinse it in the lake. Reinstall the charcoal bag, black foam pad, then the blue white filter sheets, blues side up and restart the pump.
    You can reuse the blue white filter material. This material can be purchased from aquarium stores or directly from us.


Fill the tank to the proper level, which is just to the bottom of the filter box. There is a line on the filter box to indicate the proper level. Over filling will flood the filter box and slow the filtering process. If city water is used, be sure to include a de-chlorinating chemical. Sure-Life Dechlor (LCR) is added at one cap per 10 gallons. Be sure to use non-iodized salt which can be obtained at any grocery store.

  • Add the Sure-Life product that supports the specific bait you are retaining per the manufacturer suggestions. When your choice of bait is freshwater shad, non iodized salt should be used one cup per 10 gallons.
  • Foam formed on the surface of the water in a tank can rob the water of extra oxygen it could contain. Foam can be removed by adding Sure-Life Foam-Off one drop at a time. Wait a few seconds after adding 3 or 4 drops if all foam is not gone add a few more drops.


  • Baits should be shaken from the cast net straight into a transfer vessel containing water where culling must be done to eliminate loose scales and unwanted baits. When culling, use a small net instead of your hands to place choice bait into the tank.
  • After you have all the bait you need, pour the contents of the transfer vessel back into the lake and return any unneeded baits to the lake.


  • When adding bait to a tank, always try to keep count. Never over populate your tank with a bushel baset catch dropped directly into the tank. This results in a congested tank and over-contaminated water. Bait usually die quickly because contaminates (scales and debris) enter the bait's mouth while breathing and cross over and lodge on the gills, preventing the bait from receiving the air needed. Never keep small bait fish that you don't intend to use because they steal oxygen needed by more desirable baits.
  • Keep in mind that the larger the bait, the small the numbers that can be kept. The 30 gallon tank will keep approximately 30-36 6" baits and 48-60 4" baits. The larger 50 gallon tank will hold bait in the same proportions.
  • The oval insulated tank is constructed to hold water temperatures down in hot summer months, preferably 70-80 degrees. This will not give the bait thermal shock like taking it from 80-90 degree water and dropping it into 70 degree water. Rapid changes in the temperature can cause shock. A simple thermometer can be used to accurately monitor the water temperature. A good method of reducing the water termperature is to use water frozen in a half-gallon milk type container which can be reused. If using drink containers be sure to have re-sealable tops. Another trick here to put some salt in the container prior to freezing which will cause the ice to freeze somewhat cooler.


  • After releasing all unused baits from the tank back into the lake, remove the plug from the back of the tank and allow the water to drain into the lake. If you are using a separate pump to drain the tank, insert it into the tank and drain the water over the side of the boat.
