water change

[baldomero]

just curious can i do a 50% water change once a month instead of 10 every week.

That would be a bad move. The key to success is stability. Small changes are best. The ultimate would be 1-2% each and every day! Large changes would only be used in the event of a catastrophy.

the more frequent the better with maintaining a minimum of 10% a week.
