setups is a fairly common practice, therefore id say its pretty effective. as for replacing the macro every 2 weeks or so, thats unnecessary. all someone has to do is trim the macro back every few weeks. thats it.
if the phosphates and nitrates are that far off the charts
macro's are basically useless as they can only do so much ,they would take forever just to catch up and ex-orb all the excess nitrates and phosphates , remember they are not a miracle worker
macro's yes act like a sponge but with readings that high they would need to be changed out constantly as they are only able to ex-orb so much , macro's in no way are a quick fix they will help keep the nitrates and phosphates stable and under control , waiting till it gets to the point where it gets out of control macro's wont help much, this is where big water changes are needed to bring them down to a safe level , now once the tank is stable again yes macro's will help keep things in check , but it's up to you to change and replace them every so often , remember not all macro's will act like a sponge and some will ex-orb more than others , just like some macro's are good for certain things others can be harmful
I've been playing with macro's almost 2 years now and learned a lot about the benefits of macro's and also the down falls of macro's ,
