I once had a switch that every six minutes redirected the 120 volt power between pump A to pump B. It broke and was discarded, and now I want to build another one as a DIY project. Radio Shack parts?

AquariPure Nitrate Filter, miracle product?

I read so testimonials on this product, then read their sales pitch on their website. The claim is that all other biological filters, sumps, refugiums, DSBs, etc should be discarded because their product takes waste (ammonia) and converts it all the way through the cycle to harmless nitrogen gas.

Seems too good to be true.

Thoughts?
