filtered water

Hi, just went through the process of evaluating RO, RODI, etc. to determine best route for my new 75g tank. My tap water is GH 8, KH 5, Ph 8.4 and 285 TDS. I bought a double chlorine/chloramine filter (as chloramine was high at 2.5 ppm. So the filtered water is now GH 6, KH 2-3, Ph 7.4 and 283 TDS. I mixed 1/4 filter to 3/4 tap and got a KH of 3-4 (Ph still 84). Does this make sense to go with this as my water (for angels, apistos) and use some wood to steady/raise KH a bit. Do I still use Prime just in case there is chlorine or ammonia? Oops, maybe I should post this in fish? PS - GH in mixed water is 6 to 7.

Oh no, just occurred to me that I should mix the water to get the GH for my fish (not KH), which should be about 2 to 6 GH? Then try to keep the KH steady? I am getting lost again, help!!

1) Make a blend (RO + tap) that sets the GH correct for the fish.
2) Then make the KH about the same, and lower is OK. For these fish, I would not raise it, even if the blend makes it about 1 degree.
3) If these are black water fish (I think they are) then filter the water through peat moss.

The pH ought to be at least somewhere in the ballpark, but it is not so important.

mixing water for ideal parameters

Hi, fish mix:
cichlid - cockatoo 5 to 19 dGH
tetra (blue or green fire) up to 15 dGH
cory (schwarts or emerald green) 8 to 10dGH
otto 6 to 15 dGH
angels (koi or marble veil) 5 to 12 dGH

Here is what I can find, but part of the issue is that info is inconsistent. I understand many fish are typically captive bred and more adaptable, but don't know which parameters I should aim for. Diana, you were helpful in past and said I should match GH to my fish, keep KH steady and not worry much about pH.

I read that KH should be 2 to 4 in order to buffer my high pH (8.4) and use peat, wood, and SC acid buffer.

So....which is a better starting point/easier to maintain: a mix with RO:
1. my chloramine filtered water at 6 dGH, 2-3 dKH, 7.4 pH or
2. tap 8 dGH, 5 dKH, 8.4 pH

It's hard to lower pH so maybe the filtered water is better and raise dKH with SC Replenish as needed to get my mix and use this for the first fill (75g) and top offs?

Sorry for so many questions, but I am hoping to get this off to as best a start as I can. It seems I think I get it and then read something else and get confused again!

I would use 1. and not bother altering the KH. 2-3 degrees is fine.

Oh sorry, another thought! I could just use the filtered water and then top off with RO?
