Rowa phosphate-How much do I use?

[LeanneP]

I just got Rowa phosphate to add to my tank and I a little confused on how much to add. The container is 500 ml but they are saying to add 100 g for up to 100 gallons. What is the conversion to mls or table spoons as I know it depends on density of a material when it comes to conversion.

i just went through this.... if your running it in the phosban 150 reactor you need to put more than you need to in so that it will work right, then just run it slow....

but it will work.

Don't let the title fool you - this is a good read

Looks like you need to know your PO4 level, then go from there

If you can't convert the mls to grams, use a measuring cup and measure mls

What is your PO4 reading right now ?
500ml removes 3ppm in 500g - so do some math based on that

If you missed the read, start with a smaller amount and bump it up over time
Stripping PO4 from your system too fast can cause unwanted results :surprise:
