Quick assessment to evaluate the nitrite levels in both freshwater and marine aquariums and ponds

  • Nitrite is a harmful nitrogen compound that arises when the bacterial ecosystem is disrupted or during the establishment of a new aquarium. This test provides precise measurements of the nitrite levels in your water.
  • Utilizes a laboratory-grade comparator system to adjust for the natural color of the water: simply fill glass vials with your sample, add reagents to one vial, position the vials in the holder, and compare the results against the color chart.
  • Application: when initializing a new freshwater aquarium, conduct tests daily for three weeks. For marine water setups, test once a week. Also recommended when dealing with fish illnesses or fatalities.
  • For thorough instructions and troubleshooting advice regarding water testing, visit the JBL website under Essentials/Aquarium or Pond.
  • Included in the package: 1 nitrite test kit providing approximately 50 measurements, complete with 2 reagents, 2 glass vials with screw tops, a syringe, a comparator block, and a color scale. Reagent refills are available for purchase separately.

Too narrow at the toes, even for narrow feet

Too narrow at the toe. I have narrow feet, but I could feel my toes being squished as soon as I stood up in these.. Bummer.

Size: 7, Color: Brown Patent
very cute shoes i love them, the quality is great these are my first pairs of Steve Maddens and they did not disappoint. i wear size 7 but could’ve gone maybe a half size up if it was available, they run a little smaller but maybe i jus have huge feet lol, the color is so cute dark brown matches my purse. i haven’t wore them out yet so im not sure about comfort yet but not all heels are comfortable so who knows, pretty hurts !!!

so uncomfortable
Size: 9, Color: Champagne
These shoes are cute but UNCOMFORTABLE. The toe thong makes them impossible to wear. I wore them for 5 minutes just trying them on and my feet hurt as I’m writing this. Couldn’t recommend less. Plus, the holes that the strap fits through aren’t lined up properly and are difficult to poke through. Felt like I got the made in china version.
