regular water changes thing of the past?? who doesnt do them who does????

[MMAX]

Used to do 20% bi-weekly on my 100 gallon and really noticed a difference in my SPS. Started dosing Prodibio and switched to 10% bi-weekly changes with the same results. I have been doing this faithfully for almost a year and the growth rates of my corals have been awesome. Before hand, I was a real lazy water changer--the only changes I did was topping up fresh water from evaporation.
