So it is suggested to do a water change of about 20-25% every few weeks (3-4
weeks). Is this 25% of the tank? or 25% of water in the tank after
evaporation?
So I have a 50 gallon tank, is that a water change of 12.5 gallons? Or from
the 40 gallons (after 10 gallons have evaporated) a 20% water change (10
gallons evaporate + 10-12% of tank)?
Thanks

You should be topping up on a regular basis so that your water volume is at
or
at least near capacity (or wherever you normally keep it).
You need to keep in mind that as the water evaporates it leaves the salt
behind causing
an increased salinity. Keeping your tank topped off with make for a more
constant
and stable salinity which, of course is important to the health of your
critters.
That being said, i think i was doing about 10-12% on my 50 every other week
or so...

Although I don't know any Best that applies to all tanks regardless of
the specific set-up, I have noticed what appears to me to be a striking
difference between my 29 gallon tank that I dismantled and the 55 to
which I transferred the rocks, corals, and fish and to which I added a
couple fish. The smaller tank had a *needier* appearance, so I changed 5
gallons every week; after 2 weeks the larger tank only seemed to need a
little vacuuming in one corner, so I changed only the same 5 gallons.
That's one fourth of what I was doing. The corner looked like a little
cesspool and I think it may be the Kole Tang that has trained himself to
sort of sleep in one area and poop in another. Each of the five fish
and three shrimps definitely has a favorite sheltered spot, but I'm
surprised at the sort of toilet training. Bottom line, if the tank
looks unclean in any way or tests indicate a need for change, I change
the amount of water that vaguely appears to do the job. Science, this
is definitely not.

You may find that the accumulation of detritus in one area is not due to the
tangs excellent toiletry habits! It is more likely to be a dead spot in your
water flow, i.e. an area that is unreached by the power heads (or whatever
means you have of generating currents). You may need to re-direct the flow
or add power heads to cater for this.

I did think of that and redirected the flow, but I rather liked the
thought of my tidy tang scurrying over to his little outhouse in the
deep. There are other clues that you are correct, however.
