kg4izw,
AP kits are mediocre, I only use their nitrate tests. Excellent high grade tests are Salifert once you geet more into the hobby.
I would suggest you check the Chem forum here, and try to find some sites which explain the chemistry behind reefing, because alk is not the same as pH, not even close. There is a significant amount of chemistry and biology involved in reefing, the more you know up front the fewer mistakes you will make.
We've all had to deal with this.
Do not get sucked into the newbie habit of buying all sorts of chemicals.
You can be very successful with only the following:
Good RO, RO/DI water source
Good salt mix, IO, Kent, etc.
Arm and Hammer Baking soda, for intermittent alk boosts, not for regular use
Some form of calcium chloride, for intermittent cal boosts, not for regular use
Mrs. Wages Pickling Lime, AKA Kalkwasser, which is a balanced alk/cal for regular use. Balanced means that once you're levels are in the right proportion, you only need to add this product to kep both at the appropriate level.
Also, there are 2 step alk/cal supplements available if you do not want to use kalk, they just are a bit more expensive, but probably better for the beginner.
Rookie mistake we all have made and still may make, using Alk to raise pH. Don't do it.
Randy is the Chemistry forum mod, and has written a number of papers on many aspects of reefing/chemistry. I would suggest you keep this article handy, and refer too it often until its almost second nature

Good luck, happy reefing.
Some form of calcium like Turbo Calcium. Id

I ordered a Aquarium Pharmaceuticals kit from Dr Fosters and Smith for $13.69. It says it has over 550 tests and includes tests for PH, ammonia, nitrite, and nitrate. But it does not have calcium or any other test. I assume that alkalinity is the same as PH right?
