We thought about it, researched it, talked to friends about it, tried it and did NOT like it!
This may work for some, but didn't work for our farm... I haven't seen a video or heard a review yet from anyone who didn't like them (though I'm sure they are out there), so thought I'd share ours since we just didn't!
It worked GREAT for the mosquitoes, just not to the algae and cleanliness of the tank... so take from this what you will and have fun with yours!
