I have both the API Master and API Reef test kits. Actually, I have never heard GOOD things about them, but take them for what they are. Inexpensive tests.
The API Master has pH, which gives a good indication of approximate pH, Ammonia is hard to read at low levels and hard to tell if it's 0 or 0.25ppm, nitrite is fine, but that always reads 0 after the cycle, and Nitrate. Ohh, nitrate! There is also a nitrate test in the Reef kit, and I have used both at times for comparison. Huge different readings on the same test. Exp dates are only 1 month apart too. Junk.
For the Reef, I have yet to compare with a higher quality test, but my new SeaChem tests should be here by the end of the week and I plan on comparing pH, Alk
, Calcium. I gave up on the Phosphate test as it always read 0 or .25 and I would do 2 tests back to back with different results. Opened a new Hanna checker for phosphate and very happy with that.
I will continue to use the Master kit for Ammonia, Nitrite and Nitrates as my system keeps all those at 0 (confirmed by LFS
) and I only need to watch for changes from that.
I will NOT use the Reef kit and will be using the SeaChem tests for things that MATTER, including pH and Alk
(1 test), Calcium as well as less critical tests like Silicate and Iodine. My magnesium test is a seperate test, but I can't remember the brand.
