API Test Kit and Salifert Test Kits Need Help

I'm going to be buying the API Reef Master Test Kit Aquarium Pharmaceuticals Reef Master Test Kit

and plan on buying some Salifert test kits. I remember people say they don't use two of the test kits from the API so instead they use two of the Salifert. Do you know which ones they are.

 

I rarely used the Phosphate kit but you may if you have an issue. It just doesn't measure low enough.
Salifert I like the magnesium kit.

 

ok, so just the magneisum for salifert, i'll be needing a phosphate test kit since i don't have one, i need all new test kits because i'm out of mine

 

also whats a good refractometer,i can't have anything to expensive

 

is this Marine Depot Aquarium Refractometer a good refractometer

 

I got this one on ebay which works well . The PH meter isn't bad but I wouldn't trust it too much. hehe
SALINITY REFRACTOMETER + DIGITAL pH METER AQUARIUM - eBay (item 330373642917 end time Dec-02-09 04:41:05 PST)

 

would you buy that one over the one from marinedepot

 

ohh, shipping is expensive, i think i would rather get the one from marine depot

 

I bought the API reefmaster because I needed a phosphate testand was hoping the calcium test would be easier to use than the salifert kit I already had.Though the calsium test really isnt any easier or quicker to use and the phosphate test is hard to results at low levels, I think its a good kit for the money since your getting all four tests ror about the same cost as one salifert kit.If your doing sps I would go with salifert for better accuracy.

 

i'll eventually be getting sps but for for a while it's softies and lps. I just need something because i'm out. I'll be ordering the stuff tomorrow

And one more thing. Since i really need a test kit and will be concentrating on softies/lps for a while, would it be ok if i hold off on the salifrt, as right now with tight money i'm only getting the things i really need right now
