Water changes

[marie]

It's interesting that nobody is speaking up for the small water changes.

It was comments like this

Well I had done a 50 % water change a few days ago(risky I thought myself )

and this

Really what I would do is (here come the flames) a 80 or 90% water change

that got me curious.

It's not just canreef but on every reef forum I visit, there is a group of people who will tell you to never change out more then 10-20% of the water. I think that a lot of tank crashes could of been saved over the years if people were more willing to trust the lone person who says "Do a 90% water change"
