Reverse Osmosis Water Parameters

What kind of buffers/ chemicals do i need to add to RO water to get the ph, gh, kh right?

ph= 6.0 (as low as test kit goes)

i want to use seachem stuff and phosphate free and im aiming to ~7.0

i was told by lfs that i should use the alkaline and acid buffer using the 1:2 ratio.

any sujestions?

also does flurish add phosphates to the water? my phospahates are off the charts high and i have a minor algae problem

I used Baking soda for KH, epsoms and calcium chloride for the GH.

I believe the acid buffer contains phosphates, and the alkaline buffer is mostly (if not all) baking soda.

Flourish has phosphates in it, but it's negligable. Flourish is used to add trace elements.

Lets see....

I believe I added 1/4 tsp. of epsoms, 3/4 tsp of calcium chloride, and a half tsp. of baking soda. I only added that much calcium chloride to keep a 3/1 ratio. I'm a newbie too lol.

I upgraded my tank and now I don't feel like adding RO water. I got a hot magnum and it removes any crap in my well water anyway so I don't care anymore. Just some clay stains. maybe that's iron lol.
