Would these systems not be used untill a semi mature tank or

If it aint broken, dont fix it!
If your tank is coming along nicely right now and your parameters are staying relatively in the right range then just keep doing your wc's!
Personally I think it would be better do do 12% every week as opposed to 25% biweekly.
25% bi weekly would technically be changing more water.
But coral like stability for the best growth and coloration. So for 2 weeks your parameters are dropping, dropping, dropping, then spike!
Now with a weekly wc you might need to bump it to say 15% to have the same added value of removing DOC's and other organics and replenishing elements but its pretty close to the same and would be more stable.
There is simply no replacement for water changes!
I can not state strongly enough how good water changes are both for removing everything you dont want, and replenishing every thing you do want.
If anyone has had the pleasure of meeting Anthony Calfo before he will tell you all about his tank he used to have where he did 90% weekly wc's. He would drain the tank the the bottom so the fish could barely swim, then refill with fresh sw.
No skimmer
no additives
nothing
But he will also tell you how he lived very close to the IO plant and would just drive down the street and pick up some in his pickup truck, and how crazy cheap it was for him.
So back to reality as this is not at all viable for us here!
