Large tank water changes

Water goes into the sewer through a clean-out just outside the fish room.
These short videos show the process for a 60G dry hands water change:

i think not doing water changes would end up being a bad idia. I cant imagine investing is a large and expensive setup, only to neglect doing water changes on a regular basis. I have a 200 with a 110 sump that holds perhaps 50 gallons. because of the volume of rock that I have, I am not exactly sure of my total volume... I would have to drain the system dry to know for sure, and that might not be one of my best idias...
.... I simple drain two tubs of water from my display tank (siphon), right up to one of the lines made into the tubs. This leaves just enough water in my sump to be able to leave my pumps running. I then simple drag my rubbermaid can, that is filled to the line that is made in that container with my premade water, to my tank (just around the corner). I pump back into the sump with a powerhead, and the level in the DP never even drops. I think its about 30 gallons, but im not positive. A bit more than 10 percent, but i do it this way because one trash can full is exactly the same as 2 tubs full for me... Just convienient.
The first time i dump the trashcan full of saltwater on my living room carpet, I might have to modify my routine, but I guess that would be another thread

i use a two outlet timer from lowes.
it turns on for 5mins per day.
one outlet drives a pump from teh water return part of teh sump
and it's output goes to the waste water bin (which goes into the
normal drain).
the other outlet drives a pump in the pre-mixed salt water bin;
its output is in the refugium part of the sump.

overall, this yields about a ~1.5% change daily (i have a 200gal DT).

Re: Large tank water changes

Mine are very low tech. I have a 110 gallon tank with a 66 gallon frag tank. Both drain separately to a common 29 gallon sump. I turn off both return pumps to start. I siphon 20 gallons from the display into 5 gallon buckets cleaning detritus from the display the overflows and the sump as I go. The corals are exposed a little when I do this. I then fill the display back up pouring water straight into the diaplay and turn on its pump. Next I remove 20 gallons from the frag tank siphoning off the bare bottom of it as I go as well. I also fill it back up with 5 gallon buckets. I guess it is time to use the mag 9 mixing pump in the 44 gallon brute to pump the water back into tanks. They are very close to the brute.

I also have a 210 with a 40 gallon fuge and a 30 gallon sump. I siphon the sump water straight into the yard from this tank and fill it manually by dumping buckets into the display. It is on a different floor from my mixing trash can so it would take a lot of plumbing to fill it with a pump.

I get a lot of exercise when I change my water but I actually like that part.
