Water changes still need to be done on a regular basis while using products like these. The product you are speaking of is a carbon source. So I would research carbon dosing or atleast understand it before using.
Another thing I would look into is why you feel you need to use this product. If 20% weekly changes are maintaining nitrates and phosphates and you are not overstocked or overfeeding then you should not need to use this product.
Also all those supplements are not required if you are maintaining there levels with water changes. Only heavily stocked coral reef tanks will require these forms of supplementation on a regular basis.
A link explaining water changes.
