Review on 🐠 Brightwell Aquatics Phosphat-E - Efficient Phosphate Remover for Marine Fish and Reef Tank by Alexis Henderson

DO NOT OVERDOSE! If you follow the directions, keep an eye on the water displacement, and don't overdo the dosage, it's amazing. My PO4 was over 1ppm, since my kit only reads 1, 2 or 10 it was difficult to get an exact number. Therefore, I dosed a maximum of 2.5 ml per 20 gallons for my aquarium. The next day it measures at 0.77 ppm, I dosed the maximum value for my aquarium again and as described in the bottle it fell exactly 0.25, I know that because I have a Hanna ULP tester, the new one was mine Reading now 0.52ppm, I have not seen any shock in coral, inversions, fish or macroalgae in my tank. So moral of the story, follow the direction and it will work as advertised.
