I do 20% of my 70 gallons once a month. My zoanthids are a good indication when it is needed...they shrivel and if I don't do the water change they melt away.
Even if we dose for this and that, there are trace elements that can only be replinished by water change.
Once a month is not too bad though, as I used to do 30% each day for my discus or my nitrates would be off the chart. It's less costly for freshwater of couse as I only needed RO water and that's it, but it was a pain.
