I want to pick up a Refractometer on eBay......! What brand of refractometer do you use.....and NO I don't want to use my plastic-salto-meter anymore ! ! ! And I want to get an instrument that measures the Calcium level !

Who makes a trustworthy Calcium monitor..???

I asked the same thing not too long ago. Went with the Premium Aquatics Blue for like $45. Works great, would buy it again.

So what does everyone do to test their calcium other than take it to a LFS and let them do it.....?

Marine depot has their own brand refractometer on sale this week for $34.99 if I'm not mistaken. It's a great deal.

UH_OH_5_OH, Salifert calcium test kit is the best according to most people. Easy to use and very accurate. It's a bit more expensive than other brands, but it's a good investment.

I got my refracto from PA ( www.premiumaquatics.com ) great unit and overnight ground shipping if you are in IL.
I got the cheapest one they had there.

Yes, the Marine Depot refractometer (what I use) is on sale right now. I'm not sure if this link works:


As far as Ca measurements, the Ca meter aparently stinks. Kits are supposedly the way to go. I've used both salifert and seachem and prefer seachem because it is a little easier. Either would be fine:
