Phosphate removing granules work! Iron and aluminum phosphates are simply very insoluble. So, these products will remove phosphates from the water. The use of phosphate-removing granules are indicated where a phosphate test indicates high phosphates are causing an algae bloom. “Blue-green algae” blooms are very commonly caused by high phosphate in the water.
So if a 95% water change doesn’t remove the phosphate, phosphate-removing granules are a very good option.

The author, David Bogert, is a certified chemist, something that is only useful in the sections on chemicals such as conditioners and fertilizers. He has about 43 patents, mostly in the medical device field, which only helps with some DIY designs. But he also spent much of his life as a scientific researcher working on literature research, data analysis, statistics, and a little-understood field called “experimental design.” This experience is very applicable to ALL fishkeeping science. The author has been keeping all kinds of aquariums and all kinds of fish for over 54 years. He currently has ten large and many small aquariums. But note that he is not an “expert” in all aspects of aquarium keeping. The ecology of an aquarium is far too complex for anyone to be a true “expert” in all the different aspects. One can only search the journals and books for relevant research in each individual subject.
