Hey everyone I was just curious what the best test kits are? The one I have right now can just 100-300, 10-30, etc. Deppending on which test. Could I get a little help?
For Alk, PO4 and NO3 I like the Red Sea Pro. Red Sea for Ammonia and Salifert for everything else. I've heard good things and would like to try the Hanna Alk, low range PO4 and copper.
I like Red Sea Pro, lots of folk like Hanna checkers. One thing I am doing from now on however is baselining any new kit or refill against my existing kit. The first Red Sea Phosphate Pro kit I got told me I had 0.08 ppm Phosphates when I had 0.00. The next one I got (which was their new model with different reagents) was accurate.
When I change kits or reagents in future I will baseline against my current ones for a few tests to ensure if there is a seeming variation in accuracy that I can then try to account for it. At least within the margins of precision that we can expect at a hobby grade.
