I am going to get a new 75 gallon tank, hopefully this weekend. I want to do saltwater but probably won't at this time because of the start up costs. If I do freshwater, I would like to have african ciclids but my KH is 1 and my pH runs about 6.8. How many problems would I run into in trying to get the KH and pH high enough for them? I don't want to be in a constant battle to keep their water stable.
