Which phosphate test kit do you use?
Apologizing in advance if this topic has been beaten to death already... yes, I did a search, and also read all of the suggested posts when I typed in the title of this thread, but still was not satisfied with the results.
I would like to know which phosphate test kit you have used and found to be reliable and accurate?
We purchased the API phosphate test kit. Well that was a mistake to say the least. I found the readings from both aquariums to be darker than even the highest reading on the card, so I tested the tap water. That showed less than what was in the aquariums, but still high. I tested distilled water and still got a reading of 2.0.
I cannot afford 60something dollars for the LaMotte Phosphate kit so that is not an option. Any other less expensive (say under $20) kits that will give me an accurate reading?
