The reason I said it will save you money is because most of us hobby breeders are not going to use a 32oz bottle of RGCOMPLETE in 6mths before it expires whereas a bag of rotigrow plus has a shelf life of 4x as long. To battle the ammonia issue all you need is small 5lb container of ClorAm-X($40) which you will need anyway to control the ammonia in your larvae tanks. Normal water changes in the rotifer buckets will maintain steady PH levels. Everyone has their own methods, but this is what works for me. Good Luck!!
