I'm a fan of Seachem products anyways, but this really is excellent at making your water safe for your fish. It may seem a lot more $$ than some of the other brands, but its more concentrate so you actually use much much less of it. 1 capful treats 50 gallons, whereas most pet store brands 1 capful only treats 10 gallons. The only thing to keep in mind is that it that prime converts ammonia from free ammonia (the type harmful to your fish) into ionized ammonia which is non toxic - the problem being is that most home test kits will still give you a reading of ammonia because of this. Don't think its not doing its job!

I bought this software after looking around for reviews for a good software pkg. This software received multiple good reviews by various respected web site that deal with computers/software/hardware... so far I've been well served, owned for a few months without any issues/infections.
