What to add to pure RODI?

[Chris Romano]

I use pure RODI in my aquariums - tap water is hard as a rock, and I like to have some degree of control over the hardness parameters without too much tinkering.

Right now I'm adding:

KNO3/KH2PO4
CSM+B for traces
...all in quantities/weekly dosage in line with EI.

I also reconstitute with GH Booster (Seachem Equilibrium equivalent) to 3 dGH,
Baking Soda to 4 dKH
About .2-.3 ppm extra iron via Iron Chelate a few times a week.

Starting with RODI, do I have all of my bases covered with the above? Is there anything anyone recommends to increase my plant growth? (I've seen people using things like MnSO4 or K2SO4 to enhance growth).

Thanks in advance!

A Kh of 1 is just fine and dandy.
No need to go to 4 degrees.

I would just simply mix with that wonder crap out of the Colorado River or the well water which is even worse in most cases.
Depends on the tap really.

I mixed the Davis tap with RO at 2/3rds with 1/3 tap or 1/2 and 1/2 often times and could grow anything.

Gh will also be higher as a result, which is not bad either.
CMS+B and then some DTPA will help.
