I have strantum and calcium and iodide and another but the test kits are just soo experience. Anyway I can get away without doing the testing?

You can get away without dosing any strontium or iodine as, IMO, they are not useful for most reefers, regardless of what a kit says.

As to calcium, no. The only way to know if and how much calcium you need is somehow to test, or through long years of effort, determine what your tank needs and always add that.

More important than a calcium kit, however, is an alkalinity kit. It will be the first thing you need to dose.
