Do you have a link to the item?I found this interesting solar powered air pump on ebay that is relatively cheap considering the cost of a battery powered one. I was wondering if anyone here has one.
I would want to buy one, can someone ask him what is the air pump rated (Wts)? - I don't have my secure ID on me today... :grumpy:Here you go: http://cgi.ebay.com/Solar-Fish-Aquarium-Pond-Pool-Water-Pump-Oxygenator_W0QQitemZ290240446412QQihZ019QQcategoryZ20507QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
I don't know how many people keep their tanks near a window so I doubt this is useful. If your tank happens to be near sunlight you can run this during the day and save your battery powered one for when the sun goes down.
