Nitrate test kit?

[theyangman]

What do you guys use for nitrate testing? I am fairly confident that mine are low with my water change schedule, but I wanted to here what you guys are using for testing.

Here is what I have:

Calcium: Salifert & Hanna Checker
ALK/KH: Salifert & Hanna Checker
MG: Elos

Anything else I should be checking for on a weekly basis?

Phosphates are a biggie to test for.  High phosphates inhibit coral calcification.  I use a Hanna checker.  Am looking into getting a Red Sea kit for my nitrates and Ca.

I love my redsea kits. I seriously need to test my other parameters, but keep forgetting about picking them up when I have spare cash

I use
Algae Management multi test kit (NO3,PO4)

and

Alkalinity Pro Test Kit

API is all you need for nitrates

Phosphates are a must to monitor if housing acros IMO....
Other possibly would be par, mag, nitrate, potassium.....

And actually come to think of it, watching my po4 levels has helped me house lps, zoos, and chalice.
