I went to my LFS today and got some feeder ghost shrimp. I also wanted to get a water sample so I can get my cycling tank close to what the water is like in my LFS. Then I can slowly adjust it to where I want it. The water samples I wanted were from the community tank with the ottos and corys that I plan on getting. I asked the owner and he said the pH was at just below 7.0, which sounded pretty ideal to me! I planned on getting my home tank to a pH near that, anyways. (I can mix my well water with my tap water for differing pH.......just for info) I asked whether he used RO water, and he said "NO", and that they used some kind of acid buffer pillow.(?)
Anyways, I got the shrimp and water sample home, and started testing, when I got the results, I re-tested with back-up and additional tests. I was a bit distraught with the measurements of their water. I used more than one brand of test kit for a few tests, also. The results follow (and list which kits I used):
pH: 7.6+ (AP liquid), 7.7 (Salifert)
KH: 3.8 (Salifert)
Nitrate: 100+ (Red Sea), 100+ (Salifert), 160+ (AP liquid)
The AP liquid Nitrate test is hard to distinguish between the last three measurements (40ppm, 80ppm, 160ppm), but it got red so quickly (like the other tests) that I'm sure it's well over 100ppm. I can't really say for sure whether the owner lied to me about the pH or if the "acid buffer pillow" just wore out/needs replacing. I did notice that the KH is lower than tap water (which is about 5.4, after 24 hours), but the pH is exactly the same (7.7). I got rid of the rest of the water before testing for ammonia or nitrite......don't think I want to know!
Question that remains is should I let the LFS know what my measurements were? I get along with the people OK and they know my face and have a general knowledge of me, but I'm not sure they care! It's not a great LFS, but it's the only "real" LFS in this city, or anywhere near here (Savannah, GA.). That's a bit scary to be getting fish from a "pro" establishment with water quality like that. I may as well go to PetsMart, you know!
