what other test kits do I need?

[3n1]

I currently have the AP master SW kit ( Ammonia, PH, Nitrite, Nitrate and GH ), also a AP Phosphate tester.

I'm told I need a Calcium and ALK ( or KH ) tester. What else?

Planning on just softies and fish.

That should be it.

 

[SaltyDr]

That should do it.

I would get Salifert brand Calcium and Alkalinity kits if you want an accurate, reliable test kit. The GH is not used in saltwater.
