What are the the best testing strips out there for measuring pH, ammonia, nitrates, etc.? I would like to find something more accurate (currently I'm using API test kits with droppers in 5 mL). It seems odd to me that the assumed accuracy and tight parameters that one needs to keep to maintain a mixed reef that API's kits are even suggested to anyone from the LFS. I would like to know if someone has better and more accurate results from other testing kits for their aquarium.
My setup is a mixed reef marine aquarium and eventually my next larger tank might be seeded with this 75G (around 280 liters) I have now. That aquarium will have controllers that will have top shelf controllers with industrial grade probes. I don't have that now. What I have is bottom of the barrel test kits though, monitoring my few thousands dollars worth investment.
Again, does anyone know of a more accurate kit?
