Recommendations for alkaline hard water

[magunn]

I have hard water and it has a pH of around 8, a fully cycled tank with zero ammonia/nitrite. It currently houses some pearl gouramis, a few cardinal tetra and an ancistrus. What other species might enjoy the water chemistry and the tank mates

[famman]

Most fish will adjust to that range. Only the most sensitive like Apistogramma or Discus would have any problem at all.

good luck
