had to switch to RO/DI water
after testing and retesting i just have to use RO water
i let some tap water sit for 2 days and another for 1 day. tested each one and they were the same(using lamotte kits).
PH = 8.5
kh = 7.8 (140 ppm)
no3 = 0
po4 = 3ppm
i always used rodi for my reef but i thought i could get by with just using tap and declor, but it looks like i cant.
will potassium magnesium sulfate(mgso4) rase my KH ? i have tons of calcium hydroxide. i know i can bring up the kh with that and also use baking soda.
as for trace stuff i know i will need to be adding po4 and no3 back into the water, but how much csm+b should i add ?(i am mixing it 1 tablespoon to 250ml rodi water)(i do about 40gal water change at a time) and i need to go out and get some chelated iorn and an iorn test kit(its on order), i know the csm+g has too much CU in it to just be dosed to keep the iorn where it needs to be.
