Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
If you give me about 30-40 thousand dollars I might be able to find a used laser and then test it out!
With enough energy, the laser would vaporize the miscreants in your tank. Would most definitely work, albeit considerably cheaper to tear down your entire tank and start new!
Maybe we can talk the BOD into buying one for the club.
