water changes
 

just wondering .... on average.... what % is your weekly water change?

reply
 

-10-15% a week,shudn't be 2 much with a skimmer on hand, although
many say that a 30% water change is not 2 much at all either.

5g/40g each week which equals ~8%

really catherine that little?

15% weekly sometimes 10% if I'm lazy or need to do a big w/c on my nano

15% weekly on a 29 g tank, skimmerless

15% (40 Gal) on my 300 Gallon system weekly.

I do a 15 gallon water change on about 80 gallon system.

5g/ week on my 45 cube. However, I also only did about 5g per week on my larger tanks but they were running with large becketts and my turf scrubber.

18% (55 gal) on my 300 gal reef with skimmer and moderate fish load.
