Review on YADICO Aquarium Killer Filter 200GPH by Mindi Gefroh

I have been using this product for less than 6 weeks for 2-3 hours a day. The 'faint green' light (which cannot be seen when the machine is in my 50 gallon tank) is now out. To test this I had to take the top wooden box above the tank, then the jar directly above the tank, then place the machine in a bucket of water to see if the faint green light came on. return this product if I have not used it within six weeks.
