my 131g FOWLR

I don't quite follow the W/C bypass, are you planning water changes by dumping there and overflowing into the sump?

connecting the sumps will be fine with a 2", even 1 1/2 will be OK.

Ya, that's exactly what I had in mind for the WC tank. The FOWLR would drain into the water change tank during normal operations and then overflow into a the second sump. Then when it comes time for a water change, I cut off the line going from the FOWLR into the WC tank and turn on the line that bypasses the WC tank and goes straight to the sump. Mix new salt water in the WC tank then turn valves back to normal positions.

So you use persay dirty water to force clean water into the system?

Yup! :-) Is there something wrong with that?

yeah because your going to get a mix of dirty / clean water thus wasting half of the "clean" water.

Hmm.. not really following. Now sure how that's different than doing a water change? Take old water out, put new water in, dirty water in the display mixes with new water. Same principal or am I missing something?

If you take out 50% of the water in your system and then top off you did a 50% water change, if you added 50% new water and drained the rest you just did a 25% water change.

nope i was missing something, just messed me up because in my normal operations 1) I mix the water 2) then take out the water 3) then add fresh.

you are doing 2,1,3. For some reason I read it as you were mixing the water then draining the tank into the fresh water and then removing excess.

Wow. im sure this tank will look great.

Just out of curiosity, How do you keep your wife happy enough to have three sizable tanks? A few people on here have their spouses nagging them over a small nano tank.

Some men have all the luck

i get what you saying about the water change station. I think where people are getting mixed up on is that fact that your actually closing the line and draining the w/c tank before filling it with the new water. then opening it back up to the system

I only do 10-15% water changes a week
