I have my own api sw
test kit and the only reason I still have LFS
test my water sometimes is just double check because I know they are pretty horrible at testing. The other day when I tank just finished cycling, I tested my water around 11PM and had like 40-60 nitrate. The next day, I took a bottle of water to the LFS
to test it and they said 0-5PPM of nitrate. I tested the water again that same night and found my nitrate at about 20ppm. They did not shake the bottle like the instructions + they did not use a lid, but used their fingers. That just proves how careless they can be sometimes.
You might as why I still go to this LFS
, the reason is they have the cleanest tanks and cheapest prices around. LFS
will tell you to do something to make money even though it might hurt you.
