Testing question

I get it at 48ml which is 4 tablespoons. , that would get you down to 0.03, not sure why you are aiming for 0.003 or was that a typo?

I would first try a lower dose than suggested to see how your tank reacts to it, you can always add more.

I was told 0.03 is where you wanna be for phosphate

0.03 being the lowest .
0.03-0.1

From the calculator I use it doesn’t scale, for a 200g tank it only recommends 4 table spoons, what calculator are you going off?

RowaPhos calculator

I used a Hanna phosphorus and the reading was 30 so I went to the chart from phosphorus to phosphate so 30ppb to 0.092 ppm. So I didn’t know if I had to lower my phosphate I thought 0.092 was high

0.09 is a little high but not that bad .

So I should bring it down correct?

I wouldn’t ….,

do you have a refuge ? Cheato will slowly lower it over time .
Those levels don’t warrant dosing

Sand and rock will absorb po4, you won’t know the actual amount of po4 in the tank, you want to keep a close eye on the lvl, you could try adding a little rowaphos, if the lvl goes down but then raises faster than what seems the norm, then you could have a lot of po4 in the sand and rock, so it wouldn’t be a bad idea to remove some, algae could spring up from seemingly no where.
It’s not just a case of using the amount of rowaphos the calculator suggests, as more will be leased from the rocks and sand as you remove some of the po4 from the water.
