Water Change??

[ray28576]

Will a 5gl a week water change be enough for my 75gl? I have a little order 150lbs lr and a 1.5 inch sand bed. I'm guessing this is goin to be about a 7-8% water change each week.

I do 5g on my 29. If I were you I'd try to do 10g.

10-15% recommended. 10 gal change.

10 gallons would be better but it will also depend on how heavily stocked your tank is.

You should really try to figure out what specifically works for your tank. If you have coral you may need to do more, unless you're dosing with trace elements (which you should always test for to know how much to use). Also make sure what you change out affects your nitrate levels as needed. If you change out 5 gallons a week and your nitrates don't go below 10ppm, but you want to keep SPS coral, you need to change out more each time to get that down to 0ppm....
