storms once bubbled...
The tanks were 195 and a gift from my wife. I pick my battle's very carefully and so fully intend to love the tanks in front of her. I just did not know what kind of hazard was involved in overfilling tanks. I will probably end up just purchasing steel or aluminum 100's or maybe a bit larger steels. The LDS wants 400 for PST new E series 100's a bit much in my opinion. I have seen the destruction of an exploding tank and feel just not worth it. Thanks for everyone's input.
That was awfully nice of her.
I prefer LP steels for many reasons. However, the biggest one is that they are more negatively bouyant than HP steels or aluminum. That means less weight on the belt.
I haven't used LP 80's. However, if what I said above holds true for them, you may find the LP80's to be quite functional and pleasant to dive.
If the tanks hold 80 cu. ft. at 2400 psi, then you'll need to overfill them to 3,000 psi to get 100 cu. ft. If they hold 80 cu. ft. at 2640, then you'll need to jack them up to 3300 to get 100 cu. ft. in the tank.
I'm not advising, advocating or suggesting that you exceed the manufacturer's rated pressure. However, I've been jacking my LP 104's to between 3,000 - 3,300 for some time with no problem.
Regardless, enjoy the tanks. Your wife did a nice thing.
