yea the other mags are heavy on saltwater,but it's a great way to learn.i'm still weary of aquarium fish because it's so thin,in need a lot to read.tfh is the largest, but i can read the whole thing in 2 hours.one of you said that there are too many ads in most mags,but you know what thats where i learned that there are so many diffrent ways to maintain a tank.why i would probably still have no clue what power compacts are.those ads can be a window to the perfect product for your tank.where i live fish technolgy is fairly low.the shop where i bought my first tank sells only hagen products,not bad but not the best when you have a special needs.i scearched the whole town untill i broke down and bought a copy of tfh. lo and behold here was everything i was looking for.thankfully more shops have become avalabile to me so i dont have to mail order evrey time i want something for my tank.so ads can suck but they can be cool too.
