Is it OK to dose dry?

[[email protected]]

I was curious if it would work to dose dry ferts directly into the aquarium? I was wondering because if it was then it would be very easy to automate dosing using a relatively inexpensive fish feeder. A unit like the "Rondomatic" would work particularly well because the portions are all individually separated like in a weekly pill dispenser.

I dose KNO3 and KH2PO4 dry, as I know many do. Traces are hard to dose dry, since the dose amount would be too small to measure accurately. I have yet to see any problem from dosing dry, and the stuff dissolves almost before reaching the bottom of the tank.

Some forms of Potassium Suplphate do not disolve as well as others. If you get it in the powder form it should be fine to dose dry however.
