Thanks, really appreciate all the help. Current plan is rams, geo suri's, congos, and a severum.
One more issue that may ruin this whole idea. Got my test kit in the mail today and tested the tap water. It's showing 8.4 pH, 4dKH, and 89 ppm GH/KH. Obviously, that PH is going to have to come down a looong way; I was planning on adding some peat moss pellets to the filtration system and using some PH down solution to bring it to the desired level (around 6.5). Will that be enough, and will the water be stable after that much interference? I'm considering using a product like API Proper PH 6.5, but have no experience with products like these.
Also having trouble understanding the hardness test results. AqAdvisor.com recommends a dH of 5-12 for these fish, is that the same as dKH?

For my 75 gal, I use 100% RO/DI water and adjust my hardness in the middle of the recommended levels (5-15) - for me it's 10 dGH. Proper dGH is very important to the health of your fish.

Makes sense, I may have to go that route. Is the RO/DI water neutral, or does it maintain its ph? And what do you use to adjust hardness?

RO/DI is neutral, with a GH and KH of zero. It will impact both hardness and pH, and using 0 dGH water is really the only way to lower hardness. 4 dKH is not all that high to begin with, so any additives you use (other than RO/DI water) to adjust pH could cause a severe swing in pH.5g: Nneocaridina heteropoda.

I use 100% RO/DI water. To buffer the pH I use Seachem Acid Buffer and Seachem Alkaline Buffer. To adjust the hardness I use Seachem Replenish. The advantage of RO/DI water is that you can adjust the water to exactly what you need for your fish.
This is the RO/DI unit I recommend - http://spectrapure.com/AQUARIUM/RO-D...D-RO-DI-System
I have the same unit, but rated for 90 GPD. I adjust the water temp from the faucet to 77 deg (my tank temp) and at 70 psi it takes me about 6 hrs to make 35 gal. I'm going to get the extra 90 GPD RO membrane to add to my unit to convert it to 180 GPD, which cuts the time to make my water in half.
No matter what brand you look at, there are specific units to use for aquariums - not all RO or RO/DI units are okay to use for making aquarium water. The less expensive units are generally not able to make water for aquarium use.
