Yes I can do the math to figure out how much that is for my volume of water, but that does not tell me what level to start out with to not shock the corals by dropping PO4 too fast.

Sorry if you feel that I was being straight forward, I did not mean to insult you in anyway. But the instruction does clearly state that 100g for 100g of salt-water. If your phosphate levels are high you got to find out the source of the problem such as using tap water, live rocks leaching phosphate into the water or over feeding. Using GFO is only a temporarily solution and will not solve your problem, plus in order to starve out your algae it will take time.

According to the description it does indicate that if your tank has high phosphate you should be using 2-4 times less the amount they recommend. Since GFO needs a slight tumble, the flow to push 30 grams of rowaphos is very low so it's not going to cycle all your water volume so fast in a short period of time. Like Xenon said you could always turn off your reactor if you feel it's dropping down too fast but IMO with that much return rate your corals woudln't come into a shock plus lps/softies are hardy corals.

Another tip is maybe you should use HC GFO, it is much cheaper since rowaphos is over priced for the amount they give you plus rowa is damped so the weight is slightly heavier than indicated. If you use HC GFO you can use BRS GFO calculator to calculate how much volume you need to use for the size of your tank.

Good luck with your tank and let us know if you have any problems!
