I looked at the site, they mention 257 ppm hardness, which is fairly hard water. And the pH above 8 would suggest this is the case.

This means that without any "adjustment" you will be good with livebearers and rift lake cichlids, plus a few various egg layers that prefer harder water. If you check our fish profiles here, you'll find hardness and pH preferences for each species mentioned. Some species are relatively adaptable, some are not.

Many others will concur with me in saying it is easier to select fish for your water than to adjust water for sensitive fish. But in case you may wonder if this is possible...the best way to soften and acidify water is with RO (reverse osmosis). Peat also works, but with water this hard it would take a fair bit and need regular replacement as it gives out. Those chemical pH adjusters will not work with hard water because the hardness acts as a buffer to prevent pH fluctuation, and the end result will be fluctuating pH which is stressful on all fish.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
