Whats the easiest way to do a water change with a sump - Aquarium Advice

Squado · 11-25-2006, 02:43 PM

I was just about to do my first water change after installing a sump and was wondering if it is easier to pull the water from the main tank or just right out of the sump. Also I have a refuge in the sump, so will taking the water out of their and replacing it in such a small area affect the macro? TIA.....

In my opinion it is easier to just syphon off the water from the display tank and to replace it there as well. You can do a little light vacuum job to the substrate at the same time if you wanted to.

Assuming that your fuge is at floor level, that makes it rather difficult to syphon from. It would also be a rather large water change for the fuge.

I do the same thing. I syphon from the main and slowly add to the main.

I also syphon from the main but add back into my sump.

My sump is a 75 gal tub so maybe it is easier but I drain my sump and part of my frag tank that is in the basement when I do a water change. I have a ball valve in line that takes drain water and I just turn it on. You could easily do this with the return pump. I have done both ways. I have also dropped a mag7 in the sump to drain it as well. Keeps my carpet upstairs from getting wet
