Tell us the tank once — size, gear, what lives in it. Then photograph any water test, strips or vials, and get exact next steps sized to your gallons and your livestock. A shop charges $8 to read a test at the counter. Here it takes thirty seconds and costs nothing.
Rough numbers are fine. Everything can be changed later.
Tap everything running on the tank right now.
Tap to add. Type anything we missed — spelling doesn't matter.
Last one. This is where most problems start, so be honest.
Photograph the test next to its color chart — strips, vials or a meter screen all work. Good light, no glare.
Reading the colors against your tank… about half a minute.
Every read is saved, so trends show up before trouble does.
