Hard well water out the tap.

My well water out of the tap is 7.5 pH and high KH/GH. Apparently suitable for a cichlid tank, but not so much for the densely planted, community tank I'm wanting to establish. From what I've read CO2 should reduce the pH some, but would it affect alkalinity. What about peat moss in the filter? Most fish/plants will adapt (stable) hard water condiftions? How true is this? Maybe doing too much research lately and these numbers arent as bad as they seem. Have been reading so many posts lately bringing me in different directions. I have seen posts of tanks where people dont even test water perameters at all, and they look OK and healthy.

There are a lot of fauna and plants u can keep in hard water conditions. Discus for example, baby discus in tap r more desirable as easy to do for buyer.
Cardinals, so acclimated be fine. Will not breed.

Any livebearer will be totally fine in that pH for sure. I'm currently keeping honey gouramis, endlers and ember tetras all in my tap water that's harder than yours! All of them are doing great, but I do agree, the tetras won't breed for me.

If you want to add some driftwood or indian almond leaves, you could lower the pH if you're very worried.

Peat moss helps for sure,I used peat moss and bred angelfish in hard well water with a ph over 8.0 out of the tap,using a bag of peat in the filter.White clouds are another possibility.Tank-bred cardinals are said to do well,I just got some from a seller,and the tds of their shipping water was around 300.I should have checked the ph and kh too.

MTS? no,I just need one more tank...
