Thanks for your help !

Hi!
Okey! Sounds good. I think you will find a sand filter useful for your type of tank. Yes, we mixed that dose with RO water and then just let a slow dosing pump dose until it was finished. I think it took about three or four hours.
But try to measure before and the day after with a phosphate test like Hanna Checker Low range. If you start with a small dose you can see how much effect one gram have and then you can calculate after that.
So our routine was, dose for 3-4 hours and then bashwash the filter.
Hope the information helps!
