Always a good one too!pgordemer said:Then there is the how much water and how often to change debate.
Though the most common heard is 10-15% a week, I have always had better luck (Read as stability) with 25% every two weeks. Its also easier to do overall.
I posted the salt manufactures recommendations a few posts up. But who is to say that is not even to often and they are just trying to push more salt? Maybe it should be done more but from complaints from stupid people mixing wrong or not temp adjusting they limit the recommended change to 10-20% a time so people can't screw up to bad at one time.
10% a week/20% biweekly is probably a good starting measure with bigger systems getting by with lesser amounts and Nanos needing more often changes. Then you just gauge the tank and parameters, if nutrients are low, space out the changes more. If nutrients are high, do water changes more often.
That to me seems like a common sense approach and gives everyone a starting point to work from.
Phyl, I can understand the easier part since you only do 1/2 the work biweekly. Do you find the tank changes a little to much when you do weekly changes? Harder to keep constant? Things like Alk/Calcium all over the board? This might tie into what was talked about earlier.
