I've been doing some research on these products and am almost thinking about taking a chance on them. I was suggested the bio optim and the bio digest. What is the difference between the regular prodibio and the PRO prodibio? I have a 240 gallon display tank, 125 gallon sump, and a 75 gallon refugium. Total water volume is around 300 gallons after the sand and live rock? I would just like a cleaner looking tank and to lower my nitrates which are between 20-30ppm and my phosphates which are at 3? Any suggestions would be deeply appreciated
