Looking for stability with hobby grade test kits

[reef’r]

So I ordered tropic Marin a- and k+ supplements and I will start dosing maybe at .5ml a day for a week or so and then reevaluate and see if the 1ml a day will be okay. Watching the BRS video on it they seem to recommend waiting until your tank is higher demand than mine currently is, but I’m following recommendations here. Also with that order I will be getting some KZ flatworm stop I don’t have AEFW but I’ve seen where a lot of people dose it just for overall SPS health. Also, I did a full panel test last night and compared both my Hannah DKH and Phos checkers to my salifert kits and I was almost identical between the two, so I think maybe the new lfs I’ve been stopping by weekly should actually reevaluate their own test kits instead of telling me to check mine and watch YouTube vids to “learn” proper testing procedures lol
