That's 40% monthly...plenty in my view unless it's a really small system.

Well considering i do 30% every second day its not alot to me but then i have FW malawis and salties are much more sensitive to changes in water chemistry.

Its not really 40%. Probably an average of a little more than 10% per month after considering dilution for every 10% water change.

Explain dilution and how you came up with 10% monthly water change. What formula are you using?

Because the 10% new water mixes with the 90% old water, and then when you pull 10% more out, you are taking some of last week's change along with some of the oldest water...and on, and on...
To the OP- you do not need to be adding iodine to your tank. It's already in your salt mix.

Edit: to sound nicer
What you are saying is doing a 10% weekly water change is the same as doing 10% monthly. We shouldn't ignore the fact that more water volume goes in per month doing weekly water changes.
