I stated on another thread I was curious if heating tanks on a drip, from the drip would be possible. I'm also curious about this flexwatt tape. I've seen it mentioned on a few threads, but without any responses from those have actually tried using it. Has anyone used this successfully on tanks larger than 10g? I'm looking to try shaving wattage where I can without breaking the bank. Thanks in advance for any recommendations, whether informative or criticizing...lol
