Water change question

[scubagirl]

I do fresh water top offs when necessary so I haven't actually "changed" the water. Do I need to actually take water out of the tank and add new water or are the top-off's enough? Thanks!

this is a debatable subject however....in my opinion i would reccomend doing regular (weekly, bi weekly, monthy) water changes where you remove some water (no more than %40) and replace it with new saltwater.
this will benefit all of you tank livestock. in my opinion.

I do biweekly @ 10%
I do this amount because it doesnt seem to traumatize any animals and while cleaning/adding new salt/minerals/etc to the tank it doesnt runt he chance of shocking anyone. 40% would be a pretty drastic change and unless ur very confident in your skills to match salinity and temp I would be very cautious.

Thanks a lot of your input. I think I will give it a try starting at 10%-15%.

In my experience it works best if you really mix the salt in good as you're pouring the salt into the water bucket. Then mix & aerate for at least 24 hours before actually using the water.
