PMDD Stock Solution Question

[eric_kclee]

Some people suggest to keep 4 different kind of stock solution in 4 different bottle, KNO3, K2SO4, MgSO4, KH2PO4.

Just some question.

Can we mix all the 4 solution together into one bottle?
(care has been taken to mix the right proportion)

Will there be any reaction?

Thanks

Keeping separate bottles of stock solutions allow us to dose different levels as needed if tank conditions change. Eg. if you add more fish, you may not need to dose more NO3. Nowadays I only keep a stock solution of PO4. The rest I dose "dry" into the tank.

I don't think there's reaction if mixed together. If so, they would have reacted even when we add them separately to the tank.
