Ron, If the tanks are old they're probably bad. look on top of the tank for the year. They may look good from the top but they go bad on the bottom(corrode). the only way to be sure is to remove them and pressure test. if they are bad I'd get rid of the 2 tanks and go with one large if you can accomodate it. that will give you back your fish well. Mine had a 100 gal tank and with a single 225 I got pretty good economy. Around 1.25 to 1.5 mpg. My best was a 119 KT Mi trip and i burned about 65 gallons at 3500. I turned my bait tank into a fresh water tank for a shower and put in an above floor livewell that worked great. Heres some pics.
