Calcium Or Phos Test Kit?

[logan15]

if you could only buy one test kit for your tank and you just got a Umbrella/Toadstool Leather Coral Which Would You Buy First A Calcium Or A Phosphate Test Kit?

You really need both but if I have to choose I would go with the calcium test kit. Calcium levels are important in coral growth.
