i havent kept salt in a long time. my last tank was a 25gal with a pair of clowns and a hawkfish. i have some knowledge about keeping sw fish but its been at least 9 years since i had a setup. this time around im converting my 125gal to sw. the filter i just got is a EHEIM Pro 2 Thermofilter. basically i want to set it up since my daughter wants some nemo fish and im down with anything cool and nasty loocking. suggestions please im going to start putting it together this weekend. i plan to run the tank with just water, salt, and a hang on filter with no media to mix it up. then start to add livesand and liverock. i did that in the 25 and had fish in it in 2 weeks. i had one dead a damsel but it was sickly looking to begin with.
