You want FC to be 5 or higher at all times. CC should be 0.5 or lower. PH between 7.2 and 7.8 and if practical between 7.4 and 7.6. ALK is probably not crucial, I would aim for 70-90, but there probably isn't any reason to work on changing it unless your PH is drifting up anoyingly. Similarly, for CYA I would aim for 30-50 unless you have a SWG or really high amounts of direct sunlight, but again there is no strong reason to work on changing it. You might want to test your CH and make sure it is 400 or under.
