Thanks to both of you for your input...I always will be using the Python for WC's...now on the 10 gallon, it is very easy to do a 75-80% change with the gravel substrate, I can get down deep without worrying about sucking up sand...so I always dose for 10 gallons (1 ml)
With the 40B and sand substrate, I'm not sure I can do that much at once, unless it's an emergency and I have no choice...BUT, I will still dose for 40 gallons, just to be sure...our tap water is nasty, it even has a bit of ammonia in it!

My 0pini0n is this; pull water d0wn as far as y0u can with0ut sucking up sand, mark the glass with a marker and figure 0ut (using a v0lume calculat0r) h0w much water y0u have pulled 0ut (why this 0nly just n0w 0ccurred t0 me is a mystery- in which case Crunchy is 0n the mark, l0l) then d0se f0r the am0unt added. add the prime pri0r t0 the water and all sh0uld be well. I guess s0metimes it takes a discussi0n t0 make a pers0n see the validity 0f an0ther pers0ns statements! Thanks, crunchy, f0r making me think 0utside the aquarium!!When in d0ubt read it until it makes sense, then read it again!

And to stay somewhat fish related - thinking of going the python route soon as I added a 55G tank and hauling buckets for it and the 37 and the 20 is getting old fast. So when doing a WC, you syphon, add prime (adding enough for the whole tank volume) and then add water thru the python... all with filters off I assume. How long do you wait till you turn your filters back on? I am paranoid about doing anything to my BB by circulating some chloramine thru them...

I d0n't turn my filters 0ff as l0ng as I d0n't draw d0wn bel0w my intake- then I will. S0 in sight 0f this, I will d0se the dechl0rinat0r f0r the entire v0lume 0f the tank and then wait 10 minutes bef0re adding the water, this way the dechl0rinat0r has circulated th0r0ughly.
F0r clarity (my meth0d).... rem0ve water, add dechl0rinat0r f0r entire v0lume, wait 10 minutes with filters 0n (this will add dechl0rinat0r t0 filter t0 pr0tect BB), add water needed t0 bring aquarium back t0 capacity. D0n't kn0w if this makes sense t0 y0u but it seems l0gical en0ugh t0 me- I'm n0 genius if that helps, L0L.

+1 to Longshot's post. This is how I do my PWCs (although I don't have to use Prime).
I have a small mark on the front glass so I always remove the same amount of water. Because I make my RO/DI water, I don't want to remove more water than I have made.
Volume calculator -
width x length x height (less your sand height, glass thickness & top frame), divided by 231.
For your tank, if you have 2 inches of sand, 1/4 inch thick glass and 1-1/4 inch top frame (I estimated, check your frame height) -
Width = 35.6875
Height= 13.6875 = 37.5 gallons - it is actually less than this due to tank decor taking up room, but this would be a good number to use.
If you change out 50%, that's 18-3/4 gallons. Measure and make a mark halfway between the bottom of the tank frame and the top of your sand. Remove approx 13.75 gal (make a mark for this level if you need to), clean your sand and then remove the rest of your water to the mark you made on the glass. Lowering your water level first will also help those Hatchets to stay in the tank!

My first water change on the 40B went very well, easier than I thought it would be..I changed maybe 70% (?)....I find it AWESOME that draining the tank not only used NO tap water, like I'm used to with the 10 gallon, but I got to water my miniature roses that are on the front porch at the same time!...I was really surprised how well gravity-only suction helped clean up debris from the tank
Now, for some weird news that has be perplexed a little...I did a water test for ammonia, trites, and trates maybe 30 or 40 minutes after the WC
Ammonia = .5
Trites = .25
Trates = maybe 20?
The ONLY result I was expecting here was a lower reading for trates, which were 40 yesterday...what the heck happened?....I am clueless as to why I had ammonia, it has tested 0 for days, as well as the trites
I drew the test water, put the test kit aside for awhile, and went ahead and dosed ammonia to feed the cycled tank...then did the tests...I sure hope I haven't screwed something up
My only guess is that I stirred stuff up during the water change, to affect the results...
I am not going to panic until I test again tomorrow, at the same time I tested today
Any and all theories/comments are greatly appreciated, as usual

This has been a great thread to read along! I don't have any input, but have enjoyed reading the questions I didn't know I had yet and their answers :)

On day three and finally came to page 112 (yea, I should probably up my post count per page too). Thanks for the fun and educational time killer (and for letting me get back to reading Under the Dome)
I, like everyone else, am on the edge of my seat waiting for those fish!!
Your tank looks stellar, BTW

Welcome, and come tag along with us!....we like to cut up and have fun here, but you may actually learn a thing or two about fishkeeping if you are not careful
By this time next week, I should have a 40B full of fishies!
And thanks for the comment on the tank...the DW snot has almost totally dissipated, you can actually see that it is wood now...I'll take a few more fish-free pics before D-Day (or should it be "F-Day"?) hits next week
