i like Coral Magazine,
some LFS carry it, if not you can order it on line.
TFM is not bad, ( tropical fish monthly)
there are a few online one too.
like reef keeping
here is a not too bad list of many places to find online mags or journals
one if not the best i have seen on line so far is the
advanced aquarist.
you can also lok at the archives here to find many threas on tons of differant things
and if you are looking for something a little more in depth to read adn like scientific journals, a few of us have a bunch on many subjects..
also a god book is always a must, take a look at the book list
