Well Water
Lana, I regret that you were offended by my reply. It, of course, was not intended to do so as I was only going with what I understood from your message. Although you did memtion a 10 gallon tank, it did not appear clear to me that you housed the Bettas in it, especially since you mentioned “bettaS” (pleural). As such, with your not expressly stating anywhere in that post that you kept Bettas in the 10 gallon, coupled with the common knowledge that not more than one Betta can be kept in one tank (unless they’re females), I did not understand it to read that you were keeping Bettas (pleural) in the 10 gallon tank. If you have female Bettas, that was not clearly stated (at all) either.
Understanding your post as it was presented, I had no reason to research the history of this thread. Since it seems now, from your reaction, that these wwere not the facts, it appears as though this was just a case of mis-communication resulting in a mis- understanding. BTW, atmospheric oxygen sealed in fish bags will not go “stale” anytime soon, so there was no cause for the “caution” taken with using cups (with perforated lids) for the fish to transport them.
As for your numbers, with one ounce of water per day (for 8 days) to replace the water in an 8 ounce cup, I’d just like to point out a major factor which you are missing. With each succeeding 1 ounce water change of the 8 ounce cup, as each day goes by, you will be increasingly changing out (removing) more and more of the fresh water that you’ve been adding the previous days as part of the exchanged water. As I stated, the end result of your water changing method will result in your still having a remainder of 34.88% of the old water remaining in the cup, although I this figure is a result of carrying water changes out for 9 days. For changing water for 8 days it results in still having 43.06% of old water — and it goes like this:
One ounce water change per day, of an 8 ounce cup, for 8 days = a 10% by volume of the water being changed daily (old and/or new).
First day — Changing out 10% of the 100% of old water leaves 90% of the old water remaining (now with 10% of new water).
Second day — Changing out 10% of the 90% of old water remaining leaves 81% of the old water remaining (you’ve removed a portion of the new water you’ve previously put in).
Third day — Changing out 10% of the 81% of old water remaining leaves 72.9% of the old water remaining (you’ve removed a yet larger portion of the new water previously added).
Fourth day — Changing out 10% of the 72.9% of the old water remaining leaves 65.61% of the old water remaining (tou’ve removed an even larger portion with this, of the new water previously added).
Fifth day — Changing out 10% of the 65.61% of the old water remaining leaves 59.05% of the old water remaing (with even more new water removed).
Sixth day — Changing out 10% of the 59.05% of the old water remaining leaves 53.15% of the old water remaining.
Seventh day — Changing out 10% of the 53.15% of the old water now remaining leaves 47.84% of the iold water remaining.
Eighth day — Changing out 10% of this 47.84% of the old water now remaining leaves 43.06% of the old water still remaining (with a greater portion of the new water being removed each time, as the previous amount of it is increased each previous time). Ray
