I've kept a 75 gal for over a year now. It holds mostly small species

told me that I was changing too much water too often.

Should I curb the amount I'm changing?


All the fish appear fine, with a loss of a couple of cardinal tetras and
a swordtail over the course.

Water changes are important, so is how you perform them. Getting out
organic waste via vacuuming is important (carefull with vacuuming
around plant roots), this way you lower your nitrate levels (which over
time will stunt growth and lower disease resistance).
To me it sounds like you are doing fine, but check your nitrates, ph,
and KH before and after.
For further information there are some good articles about this he
