To obtain the best results from RowaPhos and to keep your tank at zero phosphate levels it is important when starting up a new tank or on an existing tank with phosphate levels to use RowaPhos on a permanent basis.
RowaPhos will absorb phosphate, silicates and arsenic. It is entirely safe in both fresh and saltwater systems. It does not release, when exhausted, any chemicals back into the water. ie phosphate, silicates or arsenic.
It has been used continuously on David Saxby's tank for many years at five times the recommended requirement and it is only changed when phosphate levels coming out of the reactor, where it is placed, begin to rise after approximately six to seven months.
How to use:
We recommended that you maintain your phosphate levels as follows:
In saltwater aquariums below 0.015ppm (P) (0.05ppm (PO4))
In freshwater aquariums and ponds below 0.03ppm (P) (0.1ppm (PO4))
Use of large quantities may cause a temporary drop in pH which will return to normal after a number of hours.
