how much water and how often do you do water changes? i've been doing abot 25% (15 gal in my 55gal tank) a month. would it be better to do smaller changes more frequently?
right now in our 55 we have
17#live rock (getting about 30-50 more in a week)
2 clarkii clowns
1 domino damsel
1 yellow tail damsel
1 mandarin goby
1 condi anemone
1 peppermint shrimp
2 hermit crabs
our filter system is the penguin 300
eventually we want to get maybe 2 or 3 more small to medium fish........not sure what kind yet.
